Modified Files:
        src/lib/libpthread: pthread.c pthread_barrier.c pthread_cond.c
            pthread_int.h pthread_mutex.c pthread_rwlock.c

Log Message:
- Try to eliminate a hang in "parked" I've been seeing while stress testing.
  Centralise wakeup of deferred waiters in pthread__clear_waiters() and use
  throughout libpthread.  Make fewer assumptions.  Be more conservative in
  pthread_mutex when dealing with pending waiters.

- Remove the "hint" argument everywhere since the kernel doesn't use it any
  more.
