PK stack checking
This commit adds a thread stack check when a thread is preempted. Another
check is done to the kernel stack when back-to-back interrupts are processesed.
These checks are done at a time and location in the code where it is
inexpensive to do the check, and in the case of the thread stack, a likely
place for an stack overflow to occurr. A trap will happen if stack overflow is
detected.
Two new macros have been made available
that can be used to do stack checking at any point in code. These are more
expensive so their use needs to be limited. They are currently not yet used.
