 - Fix a long standing problem where an ithread would not honor sched_pin().
 - Remove the sched_add wrapper that used sched_add_internal() as a backend.
   Its only purpose was to interpret one flag and turn it into an int.  Do
   the right thing and interpret the flag in sched_add() instead.
 - Pass the flag argument to sched_add() to kseq_runq_add() so that we can
   get the SRQ_PREEMPT optimization too.
 - Add a KEF_INTERNAL flag.  If KEF_INTERNAL is set we don't adjust the SLOT
   counts, otherwise the slot counts are adjusted as soon as we enter
   sched_add() or sched_rem() rather than when the thread is actually placed
   on the run queue.  This greatly simplifies the handling of slots.
 - Remove the explicit prevention of migration for ithreads on non-x86
   platforms.  This was never shown to have any real benefit.
 - Remove the unused class argument to KSE_CAN_MIGRATE().
 - Add ktr points for thread migration events.
 - Fix a long standing bug on platforms which don't initialize the cpu
   topology.  The ksg_maxid variable was never correctly set on these
   platforms which caused the long term load balancer to never inspect
   more than the first group or processor.
 - Fix another bug which prevented the long term load balancer from working
   properly.  If stathz != hz we can't expect sched_clock() to be called
   on the exact tick count that we're anticipating.
 - Rearrange sched_switch() a bit to reduce indentation levels.
