Jeff Roberson e4b5aee3a8 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.
