ff81dc16e0 freertos: cleanup tick/idle hook functionality 
If CONFIG_FREERTOS_LEGACY_HOOKS is kept enabled then defining
idle/tick hooks will be applications responsibility as was the
case earlier.

dc3fa14a26 CAN: Add pm_lock, fix gpio bug, update docs 
This commit does the following

- Add power management lock to CAN driver so that APB frequency does not change
whilst CAN driver is in use
- Fix incorrect flag in can_transmit()
- Refactor can_driver_install() and can_driver_uninstall() so that critical sections
are shorter
- Fix CAN gpio configuration bug on RX pin. Closes #2302
- Add docs about multiple ID configuration and fix example links

10c2cddddf sleep: fix flushing UARTs when entering deep sleep 
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.

4bfa30967f freeRTOS/Re-factor ring buffers 
This fixes multiple bugs with ring buffers and re-factors the code. The public
API has not changed, however the underlying implementation have various private
functions have been changed. The following behavioral changes have been made

-   Size of ring buffers for No-Split/Allow-Split buffers will not be rounded
    up to the nearest 32-bit aligned size. This was done to simplify the
    implementation

-   Item size for No-Split/Allow-Split buffers will also be rounded up to the
    nearest 32-bit aligned size.

The following bugs have been fixed

-   In copyItemToRingbufAllowSplit(), when copying an item where the aligned
    size is smaller than the remaining length, the function does not consider
    the case where the true size of the item is less than 4 bytes.

-   The copy functions will automatically wrap around the write pointers when
    the remaining length of the buffer is not large enough to fit a header, but
    does not consider if wrapping around will cause an overlap with the read
    pointer. This will make a full buffer be mistaken for an empty buffer

closes #1711
-   xRingbufferSend() can get stuck in a infinite loop when the size of the
    free memory is larger than the needed_size, but too small to fit in the ring
    buffer due to alignment and extra overhead of wrapping around.

closes #1846
-   Fixed documentation with ring buffer queue set API

-   Adding and removing from queue set does not consider the case where the
    read/write semaphores actually hold a value.

The following functions have been deprecated
    - xRingbufferIsNextItemWrapped() due to lack of thread safety
    - xRingbufferAddToQueueSetWrite() and xRingbufferRemoveFromQueueSetWrite()
    as adding the queue sets only work under receive operations.

The following functions have been added
    - xRingbufferReceiveSplit() and xRingbufferReceiveSplitFromISR() as a thread
    safe way to receive from allow-split buffers
    - vRingbufferGetInfo()

Documentation for ring buffers has also been added.

7a0cab0a5b pthread: Allow configuration of priority and stacksize 
The expected usage is:
  esp_pthread_set_cfg(cfg);
  pthread_create()

If the inherit flag is set, then all subsequent threads forked by this
thread will also inherit this configuration. This avoids having to
change/prefix this for each and every pthread_create() call.
