FreeRTOS: Update to r2536.

Browse source 
* Introduce sbBYTES_TO_STORE_MESSAGE_LENGTH

* Fix bug in ucStreamBufferGetStreamBufferType() - which is only used by the
  Percepio trace tool.

* Update the line within vTaskStartScheduler() that was setting xTickCount to 0
  to instead set it to configINITIAL_TICK_COUNT.

* Introduce xMessageBufferNextLengthBytes() and tests for the same.

* Add call to traceTASK_SWITCHED_IN() in vTaskStartScheduler() so trace tools
  can see the first task to run.

* Correct definition of StaticTask_t in the case that portUSE_MPU_WRAPPERS is
  set to 1.

* prvTaskCheckFreeStackSpace() now returns configSTACK_DEPTH_TYPE to allow
  return values greater than max uint16_t value if required.

* xStreamBufferSend() and xStreamBufferReceive() no longer clear task
  notification bits - clearing was unnecessary as only the task notification
  state is used.

* Correct out of date comment in tasks.c.

* Fix typo in comment in queue.h.
