Originally, when doing BLE active scan, Bluedroid will not report adv to

hwcrypto sha: Allow SHA contexts to be shared between tasks
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: account for load address when mapping cache pages
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.

bootloader, esp32: add workaround for Tensilica erratum 572
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.
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.

esp_timer: do not allow deleting timers while callbacks are dispatched
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.

This change adds optional `tx_desc_auto_clear` field during I2S driver intialization
