  Modified files:
    sys/kern             kern_fork.c 
  Log:
  Commit 6/14 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.
   - Replace the tail-end of fork_exit() with a scheduler specific routine
     which can do the appropriate lock manipulations.
