Commit 10/14 of sched_lock decomposition.
 - Use sched_throw() rather than replicating the same cpu_throw() code for
   each architecture.  This also allows the scheduler to use any locking it
   may want to.
 - Use the thread_lock() rather than sched_lock when preempting.
 - The scheduler lock is not required to synchronize release_aps.

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)
