This will be useful if a webserver is already running and the application
does not want protocomm to start a new instance.

1. esp32-pico use standard spi driver to access psram
2. for esp32-pico, flash and psram share the clock
3. for esp32-pico, psram cs io can be overwrite via menuconfig
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.
Files where stack protector is initialized should not be compiled with
stack protector enabled. This was done for Make but missing for CMake.

* 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
Fix following WiFi bugs:
1. Fix a crash bug which is caused by WiFi static TX buffer alloc/free.
2. Fix the bug that iphone fails to connect to ESP32 AP by enabling AP BAR receiving.
3. Fix the bug that ESP32 station fails to connect some APs, such as Xiaomi hotspot etc,
after reset.
Shortcircuit evaluation may cause skip of _mdns_strdup_check of any further question field, which after clear_rx_packet freed undefined memory.

This commit adds the ability for backtracing to trace from the itnerrupt to the
task stack, and across nested interrupts. Test cases have also been added.

Originally, when doing BLE active scan, Bluedroid will not report adv to
application layer until receive scan response. This option is used to
disable the behavior. When enable this option, Bluedroid will report
adv data or scan response to application layer immediately.
1. fix network channel switch function.
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.
5. add allow_router_switch to mesh router configuration.
6. support handling beacon without IE of DS Parameter Set.
7. fix Wi-Fi RX fails in a specific scenario (update libphy.a).
8. fix STAs can not detect disconnection from AP when encrypt transmission is used.
9. fix can not find hidden APs.
10. for root, modify the active scan time to 120ms.
11. remove all rc when clear parent Wi-Fi configuration.
12. fix memory leak caused by the remove announcement being sent is not released when esp_mesh_stop() is called.
13. fix modify IE encrypt after mesh is started.
14. ignore esp_mesh_connect() if mesh automatic reconnection is enabled.
15. fix reason is cleared before vote is done.
16. fix issues in the example of manual_networking when mesh network is encrypted.
17. detect and fix root conflicts when router BSSID is not set.
18. when root can not connect to the router due to NO_MORE_STAS(reason code:5), root will stop re-connection and perform MESH_NWK_LOOK_FOR_NETWORK.
19. wifi: fix the disconnection caused by receiving a deauth frame from non-parent node during scanning.
20. fix routing table redundant issue due to the remove announcement is not 100% reliable.
21. modify the max routes limitation from 300 to 1000.
22. wifi: fix ap does not deauth the sta which has not yet completed the 4-way handshake but the max replay count is reached.
Previously, hardware SHA engine "locks" were mutex semaphores. This meant that the task which
started a particular SHA session (in hardware) needed to finalise that session, or an invalid
FreeRTOS state was created.
Replace with binary semaphore which can be shared between tasks.
Includes a unit test, but unit test doesn't crash even without this fix
(some other unknown condition is required).
Bootloader used to calculate the number of cache pages assuming that
load address was aligned, while in reality load address for DROM and
IROM was offset by 0x20 bytes from the start of 64kB page. This
caused the bootloader to map one less page if the size of the image
was 0x4..0x1c less than a multiple of 64kB.
Reported in https://esp32.com/viewtopic.php?f=13&t=6952.
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.
Due to a hardware limitation in ESP32, the first four bytes of some
CSI data is invalid, not the last four bytes.
Correct a mistake of CSI sub-carrier index in documentation.

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. fix bug PHY/RTC functions called in ISR (update phy to v4007)
2. add UnitTest to test it
3. fix task watchdog bug when wifi change channel
4. disable/enable agc to mac deinit/init
state and reduce force receiving broadcast data time
1. If receiving beacon which indicates that there is no data buffered,
do not force to receive WiFi data.
2. If receiving beacon which indicates that there is broadcast data
buffered, reduce the time to force receiving broadcast data.
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.
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.
