Remove or rework assumptions in queue proofs (#603) 
This commit is paired with another to queue.c in the kernel.  To
accomodate changes in newer versions of CBMC, the
--pointer-overflow-check is removed.

Assuming the bound specified in the harness and abstracting the task pool and concurrency functions, this harness proves the memory safety of QueueSemaphoreTake. Some of the task pool functions are used to model concurrent behavior required to trigger all branches during the model creation.

This proof is a work-in-progress. Proof assumptions are described in the harness. The proof also assumes the following functions are memory safe and have no side effects relevant to the memory safety of this function:

  • pvTaskIncrementMutexHeldCount
  • vPortEnterCritical
  • vPortExitCritical
  • vPortGenerateSimulatedInterrupt
  • vTaskMissedYield
  • vTaskPlaceOnEventList
  • vTaskPriorityDisinheritAfterTimeout
  • vTaskSuspendAll
  • xTaskPriorityDisinherit
  • xTaskPriorityInherit
  • xTaskRemoveFromEventList
  • xTaskResumeAll
