Changes between FreeRTOS V10.4.3 and FreeRTOS V10.4.4 released May 28 2021

See https://www.FreeRTOS.org/FreeRTOS-V10.4.x.html

    + Minor performance improvements to xTaskIncrementTick() achieved by providing
      macro versions of uxListRemove() and vListInsertEnd().
    + Minor refactor of timers.c that obsoletes the need for the
      tmrCOMMAND_START_DONT_TRACE macro and removes the need for timers.c to
      post to its own event queue.  A consequence of this change is that auto-
      reload timers that miss their intended next execution time will execute
      again immediately rather than executing again the next time the command
      queue is processed.  (thanks Jeff Tenney).
    + Fix a race condition in the message buffer implementation.  The
      underlying cause was that length and data bytes are written and read as
      two distinct operations, which both modify the size of the buffer. If a
      context switch occurs after adding or removing the length bytes, but
      before adding or removing the data bytes, then another task may observe
      the message buffer in an invalid state.
    + The xTaskCreate() and xTaskCreateStatic() functions accept a task priority
      as an input parameter.  The priority has always been silently capped to
      (configMAX_PRIORITIES - 1) should it be set to a value above that priority.
      Now values above that priority will also trigger a configASSERT() failure.
	+ Replace configASSERT( pcQueueName ) in vQueueAddToRegistry with a NULL
      pointer check.
    + Introduce the configSTACK_ALLOCATION_FROM_SEPARATE_HEAP configuration
      constant that enables the stack allocated to tasks to come from a heap other
      than the heap used by other memory allocations.  This enables stacks to be
      placed within special regions, such as fast tightly coupled memory.
    + If there is an attempt to add the same queue or semaphore handle to the
      queue registry more than once then prior versions would create two separate
      entries.  Now if this is done the first entry is overwritten rather than
      duplicated.
    + Update the ESP32 port and TF-M (Trusted Firmware M)code to the latest from
      their respective repositories.
    + Correct a build error in the POSIX port.
    + Additional minor formatting updates, including replacing tabs with spaces
      in more files.
    + Other minor updates include adding additional configASSERT() checks and
      correcting and improving code comments.
    + Go look at the smp branch to see the progress towards the Symetric
      Multiprocessing Kernel. https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/smp
