notify: protect notify->pending with the mutex
There was a known deadlocking bug in the notify library: when the other thread set notify->pending after the according check in notify_wait(), the latter thread was deadlocked. Resolve this by synchronizing all accesses to notify->pending with the notify object's mutex. Since notify_signal_sync() was never used, we can remove it. As a consequence, we don't need notify_enter() and notify_leave() anymore; eliminate them, too.
