This proof demonstrates the memory safety of the TaskPrioritySet function. The
initialization for the task to be set and pxCurrentTCB is quite similar
(since the task handle may be NULL, and in that case pxCurrentTCB is used).
Task lists are initialized with these tasks and nondet. filled with a few more
items.
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:
- vPortEnterCritical
- vPortExitCritical
- vPortGenerateSimulatedInterrupt
