- Merge the pgrpsess_lock and proctree_lock sx locks into one proctree_lock
  sx lock.  Trying to get the lock order between these locks was getting
  too complicated as the locking in wait1() was being fixed.
- leavepgrp() now requires an exclusive lock of proctree_lock to be held
  when it is called.
- fixjobc() no longer gets a shared lock of proctree_lock now that it
  requires an xlock be held by the caller.
- Locking notes in sys/proc.h are adjusted to note that everything that
  used to be protected by the pgrpsess_lock is now protected by the
  proctree_lock.
