Log Message:
Cancellation support.
This includes implementing pthread_cancel() and pthread_testcancel(),
making pthread_join() and pthread_cond_wait() cancellation points,
introducing new states to distinguish waiting on a sleep queue
from waiting in the kernel, and introducing a locking protocol around
changing a thread's run state.
