xPendingReadyList[1] was never initialised correctly, so if a task is added to this list (ie by xSemaphoreGiveFromISR()
or similar) while scheduler is disabled, then it causes a null pointer dereference.
Bug produces stack traces similar to:

Writing values longer than half of the page size (with header taken into
account) causes fragmentation issues. Previously it was suggested on the
forum that using long values may cause issues, but this wasn’t checked
in the library itself, and wasn’t documented. This change adds necessary
checks and introduces the new error code.
Documentation is also fixed to reflect the fact that the maximum length
of the key is 15 characters, not 16.

To increase the chances that the examples work out of the box, this
change is raising the default deep sleep wakeup delay to 1ms.
If GPIO15 is low at startup, ROM code takes less time to execute
(because no logging is performed), so more time may be needed to allow
flash chip to become ready.
Triggered on make 3.81, happens sometimes on Linux and always(?) on macOS. May depend on the order the OS' filesystem
resolves wildcards in.
Includes a revert to the LWIP component to verify this is properly fixed.

Fix Dport access in interrupts
Dport accesses would re-enable interrupts unconditionally, breaking things when called in an ISR. This saves and restores the interrupt status, fixing this.
This fixes a crash in the SPI slave driver, and possibly other things.

CI: auto generate configs for test jobs
Currently CI test jobs are static configured by several pre-generated config files.
This approach have several disadvantages:
1. not flexible to select test cases to run, which is important feature of @bot
2. difficult to update test as we need to pre-generate quite a lot files
3. need to maintain extra config files in IDF
4. not flexible to support new test apps or chips, can't use some new features of test bench
Therefore we'll add assign_test stage between build and test, to generate configs for test jobs.

Make internal stack size variables in FreeRTOS 32-bit instead of 16-bit

nvs: remove search cache at page level
Since read cache was introduced at page level, search cache became
useless in terms of reducing the number of flash read operations.
In addition to that, search cache used an assumption that if pointers to
keys are identical, the keys are also identical, which was proven wrong
by applications which generate key names dynamically.
This change removes CachedFindInfo, and all its uses. This is done at
expense of a small extra number of CPU operations (looking up a value in
the read cache is slightly more expensive) but no extra flash read
operations.

FATFS fixes and tests
This MR includes a set of fixes related to FATFS, SDMMC, and wear levelling:
- `esp_vfs_fat_spiflash_mount` uses `FM_SFD` flag when creating the partition. The volume layout (given in `VolToPart` variable) was not compatible with SFD mode, so mkfs was failing. This fixes the volume layout to use "autodetect" for both volumes. Merges https://github.com/espressif/esp-idf/pull/559.
- fix `prepend_drive_to_path`function, which didn't prepend drive to path (while consuming 2k of stack space)
- fix stack overflow in vfs_fat_link function which allocated two 4kbyte `FIL` structures on the stack
- fix support for having two FATFS instances (in flash and SD) mounted at the same time
- unit tests written for FATFS on SDMMC are made common between SDMMC and WL implementations; FATFS unit tests on WL will run during CI
- fix inconsistent definition of PATH_MAX and ARG_MAX (TW12207, TW12104, https://github.com/espressif/esp-idf/issues/289)

- fix null pointer dereference in VFS when VFS implementations are added
and removed in different order
- vfs_fat_sdmmc, vfs_fat_spiflash: pass correct drive to mkfs
(previously it would always do mkfs in the first drive)
- add test case
This change moves actual test code into test_fatfs_common.c and
refactors setup/teardown code to be contained within separate functions.
For each SDMMC FATFS test, identical test is added which can run with
WL partition in flash.
vfs_fat_link opened two files to perform copy operation. File structures
were allocated on the stack. When _MAX_SS setting was increased in
ffconf.h due to wear levelling feature, the size of these structures
increased to ~4k each (~8k total). This exceeds stack size allocated for
tasks in most typical cases.
This change makes file structures dynamically allocated.
Originally, prepend_drive_to_path was designed to be a macro, and it
modified local path variables to point to a temporary buffers.
When it was converted into a function, modification to path variables
were no longer visible outside of this function.
In addition to that, prepend_drive_to_path allocated 2k bytes on the
stack for temporary path buffers. This is replaced with path buffers
allocated as part of vfs_fat context object. Locking is added around
parts of code which use these temporary buffers.
Additionally, _lock member of vfs_fat_ctx_t was placed after the
variable-sized files array, which caused the first entry in the
array to be never used. This change fixes the order of members
and adds comments.
1. fix some bugs in bluetooth sniff mode in controller
2. export some symbols to esp32.rom.ld including functions and global variables in ROM code
3. update libbtdm.a which includes "IRAM_ATTR" addition or removal for some functions

esp32: select 8M clock as RTC_FAST_CLK on startup
Even though RTC_CLK_CONFIG_DEFAULT correctly had RTC_FAST_FREQ_8M as the
fast clock, the bootloader modified fast_freq field to the currently
selected RTC_FAST_CLK (so that the clock choice is not affected by the
bootloader). The application startup code never switched to 8M clock,
which caused the default (XTAL/4) to be used as RTC_FAST_CLK. This had
caused a number of issues, such as touch pads not working in deep sleep.

Assert when a new task is started on a nonexisting CPU
Previously, starting a task on a CPU ID higher than the amount of CPUs FreeRTOS is configured with would not start the task and possibly have unintended side effects due to some out-of-bounds array writes. Assert on this so the app aborts cleanly.

optimize scan before station connecting to AP
1. Store the information of AP(ssid, password, bssid, channel, etc)
into nvs when station connects to AP successfully. If station
connects to the same AP next time, it will scan the stored channel of the AP
first.
2. Add a parameter of channel for scanning before connecting to AP.
If the channel is set to 0, station will scan full channels. If it
is set to 1~13, station will only scan the channel.

Split common SPI stuff out of master driver; add slave driver; add workaround for DMA issue.
This merge req mainly adds a slave device. In order to do this, the original master driver is refactored into common code shared by master and slave modes, and a slave driver is added.
The other things added are:
- Added a workaround for a 'feature' of the ESP32 silicon that can lock up the receive DMA channel in some situations. This can only be fixed by resetting *both* DMA channels. The workaround implemented makes sure that the reset only happens when both channels are idle
- Got rid of the automatic choice between register- and DMA-based transfers. The master (and slave) code will now always go for a DMA transfer if a DMA channel is given, and always go for register-based transfers if no DMA channel is given.
- Add in a bunch of fixes for outstanding Github issues.

add support for 32k XTAL as RTC_SLOW_CLK source
- RTC_CNTL_SLOWCLK_FREQ define is removed; rtc_clk_slow_freq_get_hz
function can be used instead to get an approximate RTC_SLOW_CLK
frequency
- Clock calibration is performed at startup. The value is saved and used
for timekeeping and when entering deep sleep.
- When using the 32k XTAL, startup code will wait for the oscillator to
start up. This can be possibly optimized by starting a separate task
to wait for oscillator startup, and performing clock switch in that
task.
- Fix a bug that 32k XTAL would be disabled in rtc_clk_init.
- Fix a rounding error in rtc_clk_cal, which caused systematic frequency
error.
- Fix an overflow bug which caused rtc_clk_cal to timeout early if the
slow_clk_cycles argument would exceed certain value
- Improve 32k XTAL oscillator startup time by introducing bootstrapping
code, which uses internal pullup/pulldown resistors on 32K_N/32K_P
pins to set better initial conditions for the oscillator.

wear levelling
This MR adds wear levelling component. It presents an interface similar to the interface of spi_flash and esp_partition. Inside, it stores data inside a partition to in a way that reduces worst case number of erase cycles for any given sector.
Also included are APIs similar to the ones provided for SDMMC to mount FAT filesystem on top of the wear levelling partition. A simple example shows how this API can be used.
