  Commit 13/14 of sched_lock decomposition.
   - Add a new parameter to cpu_switch() that is used to release the lock on
     the outgoing thread and properly acquire the lock on the incoming
     thread.  This parameter is not required for schedulers that don't do
     per-cpu locking and architectures which do not support it may continue
     to use the 4BSD scheduler.  This feature is presently not supported
     on ia64
  Tested by:      kris, current@
  Tested on:      i386, amd64, ULE, 4BSD, libthr, libkse, PREEMPTION, etc.
  Discussed with: kris, attilio, kmacy, jhb, julian, bde (small parts each)
