 - When executing the 'tryself' branch in sched_pickcpu() look at the
   lowest priority on the queue for the current cpu vs curthread's
   priority.  In the case that curthread is waking up many threads of a
   lower priority as would happen with a turnstile_broadcast() or wakeup()
   of many threads this prevents them from all ending up on the current cpu.
 - In sched_add() make the relationship between a scheduled ithread and
   the current cpu advisory rather than strict.  Only give the ithread
   affinity for the current cpu if it's actually being scheduled from
   a hardware interrupt.  This prevents it from migrating when it simply
   blocks on a lock.
