timer_process_alarm function of esp_timer holds a spinlock for the
entire duration of its operation, except for the time when timer
callback function is called. It is possible that when
timer_process_alarm releases the spinlock, a higher priority task may
run and delete the timer. Then the execution will return to
timer_process_alarm, and this will either cause a crash, or undesired
execution of callback after the timer has been stopped or deleted.
To solve this problem, add a mutex which will prevent deletion of timers
while callbacks are being dispatched.

1. Change bus reset to handle interrupted READ sequences.
2. Slow down I2C to 100khz during reset
3. If a SLAVE device was in a read operation when the bus was interrupted, the SLAVE device is controlling SDA.The only bit during the 9 clock cycles of a byte READ the MASTER(ESP32) is guaranteed control over, is during the ACK bit period.
If the SLAVE is sending a stream of ZERO bytes, it will only release SDA during the ACK bit period. The master(ESP32) cannot generate a STOP unless SDA is HIGH. So, this reset code synchronizes the bit stream with, Either, the ACK bit, Or a 1 bit.
I am stealing this delay coding from @jeremyherbert #2493 pr.
2. Change Bus Reset to handle interrupted READ sequences.
The current code does not handle interrupted READ cycles.
If a SLAVE device was in a read operation when the bus was interrupted, the SLAVE device is controlling SDA.
The only bit during the 9 clock cycles of a byte READ the MASTER(ESP32) is guaranteed control over, is during the ACK bit period.
If the SLAVE is sending a stream of ZERO bytes, it will only release SDA during the ACK bit period. The master(ESP32) cannot generate a STOP unless SDA is HIGH.
So, this reset code synchronizes the bit stream with, Either, the ACK bit, Or a 1 bit.
3. fix typo
correct `sda_id` to `sda_io` in `i2c_master_clear_bus()` @ryan-ma found it. This typo was generated when I manually edited this patch on GitHub, I should have done a Copy/Paste operation!
1. Use BIT[7:5] of EID to determine psram size
2. Add ID support for 16Mbit psram
3. Remove module reset on SPI1
4. Confirmed with the vendor that only the old 32Mbit psram need special clock timing. For other psram chips, we should use standard QPI mode.
1. add network channel switch function.
- users can obtain the new channel through the event MESH_EVENT_CHANNEL_SWITCH.
- the entire network will be moved to the same channel as the router without user intervention.
- if no router is in the network, users can call esp_mesh_switch_channel() on the root side to
move the entire network to their desired channel.
2. support not configuring the network channel.
3. support not configuring the router BSSID even if the router is hidden.
4. add allow_channel_switch to mesh configuration.
- if the channel is not specified, this value will be ignored.
- if the channel is specified and this value is set, when "fail" (mesh_attempts_t) times of parent selection
or look for networks are reached, device will change to perform a full channel scan for networks that could join.
- if the channel is specified and this value is set to 0, when a root is not elected, channel switch is not allowed.
but when a root appears, the root performs a full channel scan during the process of connecting to the router,
so even allow_channel_switch is set to 0, the root may still switch channel and eventually the entire network
changes channel.
5. add allow_router_switch to mesh router configuration.
- if the BSSID of router is not specified, this value will be ignored.
- if the BSSID of router is specified and this value is set, when the router of this specified BSSID fails to be found
after "fail" (mesh_attempts_t) times, the entire network is allowed to switch to another router with the same SSID.
6. modify the root to perform a full channel scan when esp_wifi_connect().
7. support handling beacon without DS Paramter Set.
The DMA cannot receive data correctly when the buffer address is not
WORD aligned. Currently we only check whether the buffer is in the DRAM
region.
The DMA always write in WORDs, so the length arguments should also be
multiples of 32 bits.
A check is added to see whether the buffer is WORD aligned and has valid
length.
The driver decide whether use MOSI/MISO phases according to the buffer
address together with the SPI_TRANS_USE_*DATA. However someone may assue
that these phases will be skipped when the ``length``/``rxlength`` is
set to 0. In fact it is a feature that ``rxlength`` is allowed to be
set to 0 when tx and rx have the same length, and the driver fill the
``rxlength`` to ``length``.
An error check is added when the rxlength is 0 but there is data to be
sent.
It has been observed that, in case of underflow (data unavailability) in
I2S transmission, previously filled up tx descriptors continue to get
transmitted on line, causing noise in case of audio use case.
This change adds optional `tx_desc_auto_clear` field during I2S driver intialization
than can zero initialize tx descriptor in case of underflow situation in
interrupt handler itself.

Introduced in 9c23b8e5 and 4f87a62f. To get higher speed, menuconfig
options are added to put ISR and other functions into the IRAM. The
interrupt flag ESP_INTR_FLAG_IRAM is also mistakenly set when the ISR is
put into the IRAM. However callbacks, which are wrote by the user, are
called in the master and slave ISR. The user may not be aware of that
these callbacks are not disabled during flash operations. Any cache miss
during flash operation will cause panic.
Essentially IRAM functions and intrrupt flag ESP_INTR_FLAG_IRAM are
different, the latter means not disabling the ISR during flash
operations. New bus_config flag intr_flags is offered to help set the
interrupt attribute, including priority level, SHARED, IRAM (not
disabled during flash operations). It introduced a small BREAK to
IDFv3.1 (but the same as IDFv3.0) that the user has to manually set IRAM
flag now (therefore he's aware of the IRAM thing) to void the ISR being
disabled during flash operations.
If zero-overhead loop buffer is enabled, under certain rare conditions
when executing a zero-overhead loop, the CPU may attempt to execute an invalid instruction. Work around by disabling the buffer.
New unity component can be used for testing other applications.
Upstream version of Unity is included as a submodule.
Utilities specific to ESP-IDF unit tests (partitions, leak checking
setup/teardown functions, etc) are kept only in unit-test-app.
Kconfig options are added to allow disabling certain Unity features.
transport_mode accepts enum httpd_ssl_transport_t instead of true/false.
This will allow for extension to dual mode (server running on both secure and insecure ports) in the future.
* http_sess_set_*_override APIs are now the only ones available to set custom recv/send/pending functions
* Fixed side effects to using http_sess_set/get_context inside URI handlers
Changes:
- renamed `httpd_free_sess_ctx_fn_t` to `httpd_free_ctx_fn_t`
- added a `httpd_handle_t` argument to `httpd_send_func_t` and `httpd_recv_func_t`
- internal function `httpd_sess_get()` is no longer static, as it's used in other
files besides httpd_sess.c
Bug fixes:
- removed a trailing semicolon from `HTTPD_DEFAULT_CONFIG()`
- fixed issue with failed `select()`, now it automatically closes invalid sockets
instead of shutting down the entire server
New features:
- `httpd_resp_send()` and `httpd_resp_send_chunk()` now accept -1 as length to use
`strlen()` internally
- added `httpd_sess_set_ctx()` to accompany `httpd_sess_get_ctx()`
- added a "transport context" to the session structure (next to user context)
- added `httpd_sess_{get,set}_transport_ctx()` to work with this transport context
- added "global user context" and "global transport context" stored in the server
config (and then the handle); supports a user-provided free_fn
- added a "pending func" to e.g. check for data in the transport layer receive
buffer
- added functions `httpd_set_sess_{send,recv,pending}_override()` that target
a session by ID (i.e. not using a request object)
- added `httpd_set_pending_override()`
- added a "open_fn" and "close_fn" - functions called when creating and closing
a session. These may be used to set up transport layer encryption or some other
session-wide feature
Background
Softap will send connected event after receive assoc request as before, however, STA didn't connect to softAP if need security. As our mesh design, it will send data packet after receive connected event, so change the current behavior, softAP will send connected event if have encryption

It is an ESP specific FreeRTOS feature that the ISR is always executed
on the core which calls the interrupt register function. In the SPI
driver, the function is always called in the bus initialization
function.
Hence, the ISR will be executed on the core which initialize the driver.
If the core is starved due to higher priority ISRs, or the interrupt is
disabled on the core (spinlock called, etc.), the ISR will not get
executed and SPI transactions will not be handled.
(MINOR CHANGE)
Resolves https://github.com/espressif/esp-idf/issues/2432.
The MISO signal will be delayed if the GPIO matrix is enabled.
However, delay also comes from the slave.
Previous code only considers the former case, and assume the frequency
limitations is only violated when GPIO matrix is used.
Now we are able to calculate the freq limit when extenal MISO delay is
given (feature introduced in 9c6c6ec34ab0641ace89aeb9b1a133eb6fae1a18).
The frequency limit is lower when the external MISO delay is large, and
the limit is likely to be violated even with IOMUX.

This commit resolves a blocking in esp_aes_block function.
Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.
Fix some related issue with shared using of AES SHA RSA accelerators.
Closes: https://github.com/espressif/esp-idf/issues/2295#issuecomment-432898137
When light sleep is finished on one CPU, it is possible that the other
CPU will enter light sleep again very soon, before interrupts on the
first CPU get a chance to run. To avoid such situation, set a flag
for the other CPU to skip light sleep attempt.
Tickless idle/light sleep procedure had a bug in single core mode.
Consider the flow of events:
1. Idle task runs and calls vApplicationIdleHook
2. This calls esp_vApplicationIdleHook, which calls esp_pm_impl_idle_hook, and pm lock for RTOS on the current core is released.
3. Then esp_vApplicationIdleHook calls esp_pm_impl_waiti, which checks that s_entered_light_sleep[core_id]==false and goes into waiti state.
4. Some interrupt happens, calls esp_pm_impl_isr_hook, which takes pm lock for RTOS. PM state goes back to CPU_FREQ_MAX.
5. Once the interrupt is over, vApplicationIdleHook returns, and Idle task continues to run, finally reaching the call to vApplicationSleep.
6. vApplicationSleep does not enter light sleep, because esp_pm_impl_isr_hook has already changed PM state from IDLE to CPU_FREQ_MAX.
This didn’t happen in dual core mode, because waiti state of one CPU was interrupted by CCOMPARE update interrupt from the other CPU, in which case PM lock for FreeRTOS was not taken.
Fix by inverting the meaning of the flag (for convenience) and only setting it to true when vApplicationSleep actually fails to enter light sleep.
Having two different spinlocks is problematic due to possibly
different order in which the locks will be taken. Changing the order
would require significant restructuring of kernel code which is
undesirable.
An additional place where taking xTickCountMutex was needed was in
vApplicationSleep function. Not taking xTickCountMutex resulted in
other CPU sometimes possibly advancing tick count while light sleep
entry/exit was happening. Taking xTickCountMutex in addition to
xTaskQueueMutex has shown a problem that in different code paths,
these two spinlocks could be taken in different order, leading to
(unlikely, but possible) deadlocks.
1. When WIFI task or other high priority task blocks the Bluetooth task, ACL RX buffer will use up, ACL RX buffer ptr will point to null and will never point to a valid adress. Causing errors in Bluetooth.
2. hcimsgs.h used whether flow control is on or off
Introduced in 97e3542947.
The previous commit frees the IRAM part when single core, but doesn't
change the memory layout functions. The unit test mallocs IRAM memory
from the heap, accidently into the new-released region, which doesn't
match the memory layout function.
This commit update the memory layout function to fix this.
Problem Decribe
The problem happenned when do wps with a mikrotik router
1. router always want to do connect with 32 without EAP-WSC step
2. after 4 way timeour, 32 crash
Root Cause
The reason why can not start EAP-WSC step is router's check method is RSN > WPA > WPS, when it found there include RSN and WPS in assoc, it will choice do 4 way rather than WPS
The reason of second problem is 32's EAPOL start timer didn't stop and send EAPOL start to a null pointer
Soultion
1. remove RSN and WPA ie when do WPS step
2. check mac address's pointer before send EAPOL start

Routine `spi_flash_cache2phys` sometimes return incorrect value,
resulting in failure in getting currently running ota partition.

In some cases, when data was just written into UART FIFO, transmitter
state could be still zero while the FIFO did contain some data.
This resulted in uart_tx_wait_idle occasionally returning before all
the data was sent out.
Fix by checking both UART transmitter state and TX FIFO count.
ROM definition of `abort` was removed in 9240bbb. The old definition
resulted in a panic due to a jump to a null pointer (abort member in
ROM stub table was zero). The new definition triggers a debug
exception if JTAG is connected, or goes into an infinite loop to be
reset by the WDT.
Some logging done in soc component may happen before logging via
stdout is possible. Use _EARLY version of log calls to make sure that
output is visible. The downside is that application does not have a
way to silence these logs. However since the soc component doesn’t

not impact the application.

tcp_transport component used public header files such as 'transport.h', etc. which are too generic and might collide with user or user libraries headers
This change closes#2417
In some cases, linker could choose to use ROM functions instead of the
ones defined in IDF.
For functions used in ROM stub table, this would lead to infinite
recursion when the corresponding function was called from ROM.
For crypto functions, some of these were modified in IDF, and
incompatible with ROM counterparts.
Problem Description
The reporduce steps are as follows:
1. put more than one same ssid AP in the environment;
2. set the STA mac address in one of the APs blacklist, and make sure the AP is closest to STA;
3. set the scan method in station config as all channel scan;
4. try to connect the AP which set STA in blacklist
Phenmenon
STA fail to connect after send auth or assoc with a wrong status code, but no disconnect event report and can not connect the next one in the envrionment
Root Cause
Because there are some same ssid APs in the evnrionment, when do all channel scan, it will collect all the matched AP in rc list, because rc list is not empty, so it would send disconnect event, however, we didn't do other step such as connect to other one

When CONFIG_ESP32_RTCDATA_IN_FAST_MEM is enabled, RTC data is placed
into RTC_FAST memory region, viewed from the data bus. However the
bootloader was missing a check that this region should not be

transmitted from cellphone. But for most dual frequency routers
whose SSIDs of 5G and 2.4G are the same, broadcast packets are
forwarded from 5G interface to 2.4G interface while multicast
packets are not. In order to make esp-touch work when cellphone
connects to 5G interface of these routers, esp-touch is improved
to support both multicast and broadcast packets. Meanwhile, new
APP which is compiled with Andriod or IOS library(>= v0.3.6.2)
must be used in this situation. Note that for some routers,
broadcast and multicast packets are forwarded from 5G interface
to 2.4G interface only when another WiFi device is connected to
2.4G interface of the router. Old APP which is compiled with
Android or IOS library(< v0.3.6.2) also works with this improvement
when cellphone connects to 2.4G interface of the router.
The Android and IOS library of new esp-touch APP is now available
on Github.

Four internal APIs `esp_http_client_connect()`, `http_client_prepare_first_line()`, `esp_http_client_request_send()` and
`esp_http_client_send_post_data()` API have been added for perfoming connection establishment (sync as well as async),
preparing first line, sending request and sending post data respectively.
In `transport_ssl`, `ssl_connect_async()` API has been added for establishing asynchronous connection.

Problem Description
set some of routers as the same ssid in the same channel, when 32 in the fast scan connect mode, there may no disconnect event report in that two sceanrio:
1. set the correct password and connect, if target router didn't report 32's auth req before timeout, the state machine change to init but no disconnect event report
2. set a wrong password, if router send disassoc or deauth after run, rather than wait 4 way handshake timeout, the state machine change to init but no disconnect event report
Root Cause
Because the routers are in the same channel, all of them are matched the ssid, so all of them can be instore in the rc list wait for connect, when the first one want to connect fail at auth or receive
disassoc or deauth when password wrong, the rc list is not empty, it can not send disconnect event because rc is not empty
Solution
1. put the fail the router in the blacklist
2. Judge whether there is another router can be connect, if it has, try to connect with the next one
VNC MR 561
gen_esp_err_to_name.py includes files like
components/lwip/include/apps/esp_ping.h as "apps/esp_ping.h" because all
subdirectories of "include" are used. If "components/lwip/include/apps"
is in the path of the compiler instead of "components/lwip/include" then
include "apps/esp_ping.h" will fail. This fix allows to process lines
like:
'// gen_esp_err_to_name.py: some text "esp_ping.h" some text'
in header files for overwriting the include.
Before LwIP was moved into a submodule, sntp and esp_ping were
available as the following includes:
#include "apps/sntp/sntp.h"
#include "esp_ping.h"
This commit makes header files available at the old location, and adds
a deprecation warning for sntp.h.

Problem:
The new API esp_bt_mem_release() that was added freed BTDM data to heap from esp_bt_controller_mem_release().
Now with the BT memory optimization commit ee787085f9,
the BTDM data is optimized and reduced to only 32 bytes which is not sufficient amount to be added to heap.
So, using the API leads to assert saying that the region is too small.
Solution:
Modify heap_caps_add_region_with_caps to return ESP_ERR_INVALID_SIZE in case the range is too small to create a new heap.
Do not assert if return value is ESP_ERR_INVALID_SIZE
This also fixes using API esp_bt_controller_mem_release() with ESP_BT_MODE_BTDM

Previous APIs used to set CPU frequency used CPU frequencies listed in
rtc_cpu_freq_t enumeration. This was problematic for two reasons.
First, supporting many possible frequency values obtained by dividing
XTAL frequency was hard, as every value would have to be listed in
the enumeration. Since different base XTAL frequencies are supported,
this further complicated things, since not all of these divided
frequencies would be valid for any given XTAL frequency. Second,
having to deal with enumeration values often involved switch
statements to convert between enumeration and MHz values, handle
PLL/XTAL frequencies separately, etc.
This change introduces rtc_cpu_freq_config_t structure, which contains
CPU frequency (in MHz) and information on how this frequency has to
be generated: clock source (XTAL/PLL), source frequency, clock
divider value. More fields can be added to this structure in the
future. This structure simplifies many parts of the code, since both
frequency value and frequency generation settings can be accessed in
any place in code without the need for conversions.
Additionally, this change adds setting of REF_TICK dividers to support
frequencies lower then XTAL with DFS.
`esp_http_client_write` API puts a constraint on the maximum length of the data that can be
written, which is equal to client handle buffer size, but the data to be sent can be more
than that, so in this case, this API has to be called multiple times.
In `esp_http_client_open` API, the return value of `transport_write` API, used to send HTTP
request, is not checked, and in rare cases, data written will be less than expected which will
cause a problem. So there are fixes for these minor issues in this MR.

1. when one task do deinit/init/disable/enable, especially different cpu
core, it may cause controller crash in ISR handler
2. fix while BLE is scanning, bluetooth controller is disabled cause BLE
scan is not abort.
1. Modify esp_bt_controller_mem_release() to release BTDM BSS and Data to heap if
ESP_BT_MODE_BTDM mode is passed to it
2. Add a new API esp_bt_mem_release() which internally calls
esp_bt_controller_mem_release() with the provided mode and then if mode
is ESP_BT_MODE_BTDM, releases BT BSS and Data to heap.
Background:
For Wi-Fi and BT/BLE applications, for e.g. the usecase is like when
Bluetooth is used for provisioning and once the device is connected to the Wi-Fi
AP, we can turn off Bluetooth completely. In such scenarios, it should be possible to
reclaim all the memory of Bluetooth. Although, currently this does not
happen.
Experiment:
Made the following modifications to examples/bluetooth/gatt_server :
1. Added support of simple_wifi to it
2. Moved all the bluetooth related code under CONFIG_BT_ENABLED config
option
3. Calculated the free heap in 2 similar scenarios:
i. Disabled BT (CONFIG_BT_ENABLED undefined) and checked the free
heap after STA connected
ii. Kept BT enabled and disabled it after STA connected and checked
the free heap
Ideally, the numbers for i., ii. above should have been similar. But
there was a delta of almost 30-31K. (i. > ii.)
4. Through make size-components checked the common BSS for libbta.a and libbtdm_app.a
and found it to be almost 30K. Data is around 1K
Solution:
1. Modified the linker script to mark the BSS and Data for these libraries and
free it when ESP_BT_MODE_BTDM mode is passed to mem release APIs.
2. Verified that the free heap is comparable for i. and ii. above.
Note: It is known that once this is done, Bluetooth can only be used
again post reboot.

This change removes the earlier limitation of 1984 bytes for storing data-blobs.
Blobs larger than the sector size are split and stored on multiple sectors.
For this purpose, two new datatypes (multi-page index and multi-page data) are
added for entries stored in the sectors. The underlying read, write, erase and find
operations are modified to support these large blobs. The change is transparent
to users of the library and no special APIs need to be used to store these large
blobs.
* Fixes some "noreturn" functions in bootloader utils which did return (causing fatal CPU

* Marks bootloader entry as "noreturn", preventing "user code done" from stalling boot
Partial fix for https://github.com/espressif/esp-idf/issues/1814 TW20016
(Comprehensive fix for this issue will be enabling WDT during bootloader, coming shortly.)
1. Move channel to the first row of the table.
2. Remove the condition of HT20/HT40 for they are determined by
secondary channel.
3. Clean up the CSI table.
Because address space is mapped in 64KB pages, it was possible for unauthenticated data after the
app .bin to become mapped into the flash cache address space.
This problem is solved by 2 changes:
* "esptool elf2image --secure-pad" will pad the image so that the signature block ends close to the
64KB boundary. Due to alignment constraints it will be 12 bytes too short after signing (but
with flash encryption, these 12 bytes are still encrypted as part of the last block and can't be
arbitrarily changed).
* By default, secure boot now requires all app partitions to be a multiple of 64KB in size.
Perviously host send_auto_stop flag would be set for every data
transfer over 1 block long. This caused stop commands to be sent
after CMD53, which shouldn't be done. Fix by adding an explicit list
of commands for which send_auto_stop should be set.
Send the Goodbye packet while removing an mDNS service as an "Authoritative" packet so

1. Add reading psram EID.
2. Configure different clock mode for different EID.
3. add API to get psram size and voltage.
4. Remove unnecessary VSPI claim.
For 32MBit@1.8V and 64MBit@3.3V psram, there should be 2 extra clock cycles after CS get high level.
For 64MBit@1.8 psram, we can just use standard SPI protocol to drive the psram. We also need to increase the HOLD time for CS in this case.
EID for psram:
32MBit 1.8v: 0x20
64MBit 1.8v: 0x26
64MBit 3.3v: 0x46
When 2nd stage bootloader loads the ROM bootloader, it prints a
message similar to "entry 0x40080xxx", which idf_monitor decodes
(using application ELF file) as one of the reset vectors (xxx is <
400h). This moves the iram_seg of bootloader 1k up to prevent overlap
of bootloader .text and application vectors, making the output look
nicer. There is still a chance that the entry point decodes as some
symbol in application ELF file, but at least it won't have
"Exception" in its name.
Since 94250e42a0, UART output is suspended when entering sleep mode
(deep or light sleep). This makes sense for light sleep, where sleep
normally takes small amount of time, and flushing the UART would add
a lot of latency. But this breaks existing behaviour for deep sleep,
where UART output was previously sent out before entering sleep mode.

INTERRUPT and CCOUNT registers will change outside of program control.
Making the inline assembly used to read these registers volatile
indicates this fact to the compiler.
Fixes https://github.com/espressif/esp-idf/issues/2127
The fix is for the situation when cache disabling mechanism causes
a deadlock with user tasks. Situation is as follows:
1. spi_flash operation is started from low-priority task on CPU0
2. It uses IPC to wake up high-priority IPC1 task on CPU1, preventing
all other tasks on CPU1 from running. This is needed to safely
disable the cache.
3. While the task which started spi_flash operation is waiting for IPC1
task to acknowledge that CPU1 is not using cache anymore, it is
preempted by a higher priority application task ("app0").
4. Task app0 busy-waits for some operation on CPU1 to complete. But
since application tasks are blocked out by IPC1 task, this never
happens. Since app0 is busy-waiting, the task doing spi flash
operation never runs.
The more or less logical soltion to the problem would be to also do
cache disabling on CPU0 and the SPI flash operation itself from IPC0
task. However IPC0 task stack would need to be increased to allow doing
SPI flash operation (and IPC1 stack as well). This would waste some
memory. An alternative approach adopted in this fix is to call FreeRTOS
functions to temporary increase the priority of SPI flash operation task
to the same level as the IPC task.

1. fix BLE connection missing in coex mode
2. modify other parameters to make coex priority more reasonable
3. fix modem sleep procedure trap cause Wifi disable RF when BT is
working. Such cause that BR/EDR is difficult to be connected, BLE
connection stability decrease and so on.
4. modify BR/EDR coexist duration to imrove BR/EDR connect success
ratio.
5. Due to the hardware coexist bug, BLE scan interval/window should
be less than 0x100(about 160ms). Therefore, it will cause BLE cannot
scan any advertising packet while WiFi have higher priority
behaviour(such like RX beacon, scan, TX/RX VO packets and etc.).
1. add APIs to set/get announce interval values.
2. add API to enable/disable the min rate to 6Mbps for data packages.
3. add APIs to set/get RSSI threshold values.
4. fix ap_loss.
Moved useful functions from wrapped assert functions, because option `CONFIG_OPTIMIZATION_ASSERTIONS_DISABLED=y` will remove this functions.

1. esp_ble_remove_bond_device will only remove BLE bond key and disconnect BLE device.
2. esp_bt_gap_remove_bond_device will only remove BT bond key and disconnect BT device.
As reported https://esp32.com/viewtopic.php?f=14&t=6171
event_callback() in sockets.c calls conn->socket-- to register
activity on a netconn which may not have any socket yet,
so any socket value < 0 indicates "no controlling socket"
for the netconn.
