  Modified files:
    sys/sys              systm.h condvar.h 
    sys/kern             kern_synch.c kern_condvar.c 
  Log:
  Implement mwakeup, mwakeup_one, cv_signal_drop and cv_broadcast_drop.
  These take an additional mutex argument, which is dropped before any
  processes are made runnable.  This can avoid contention on the mutex
  if the processes would immediately acquire it, and is done in such a
  way that wakeups will not be lost.
