jeff be190686fa - Introduce kseq_runq_{add,rem}() which are used to insert and remove ...

kses from the run queues.  Also, on SMP, we track the transferable
   count here.  Threads are transferable only as long as they are on the
   run queue.
 - Previously, we adjusted our load balancing based on the transferable count
   minus the number of actual cpus.  This was done to account for the threads
   which were likely to be running.  All of this logic is simpler now that
   transferable accounts for only those threads which can actually be taken.
   Updated various places in sched_add() and kseq_balance() to account for
   this.
 - Rename kseq_{add,rem} to kseq_load_{add,rem} to reflect what they're
   really doing.  The load is accounted for seperately from the runq because
   the load is accounted for even as the thread is running.
 - Fix a bug in sched_class() where we weren't properly using the PRI_BASE()
   version of the kg_pri_class.
 - Add a large comment that describes the impact of a seemingly simple
   conditional in sched_add().
 - Also in sched_add() check the transferable count and KSE_CAN_MIGRATE()
   prior to checking kseq_idle.  This reduces the frequency of access for
   kseq_idle which is a shared resource.
