Modified Files:
	basesrc/lib/libpthread [nathanw_sa]: pthread_mutex.c

Log Message:
Speed up pthread_mutex_unlock() similarly to what was done to
pthread_mutex_lock(): heavily optimize for the case of a mutex with no
waiters, and defer the waiter case to a separate function.

Uncontested mutexes now no longer use library spin locks.
