- Adjust sched hooks for fork and exec to take processes as arguments instead

   of ksegs since they primarily operation on processes.
 - KSEs take ticks so pass the kse through sched_clock().
 - Add a sched_class() routine that adjusts a ksegrp pri class.
 - Define a sched_fork_{kse,thread,ksegrp} and sched_exit_{kse,thread,ksegrp}
   that will be used to tell the scheduler about new instances of these
   structures within the same process.  These will be used by THR and KSE.
 - Change sched_4bsd to reflect this API update.
