Jeff Roberson 765b2891e8 Commit 7/14 of sched_lock decomposition. 
- Use thread_lock() rather than sched_lock for per-thread scheduling
   sychronization.
 - Use the per-process spinlock rather than the sched_lock for per-process
   scheduling synchronization.
 - Use a global kse spinlock to protect upcall and thread assignment.  The
   per-process spinlock can not be used because this lock must be acquired
   via mi_switch() where we already hold a thread lock.  The kse spinlock
   is a leaf lock ordered after the process and thread spinlocks.

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)
