  Modified files:
    sys/kern             sched_ule.c 
  Log:
   - Allow static_boost to specify no boost with '0', traditional kernel
     fixed pri boost with '1' or any priority less than the current thread's
     priority with a value greater than two.  Default the boost to
     PRI_MIN_TIMESHARE to prevent regular user-space threads from starving
     threads in the kernel.  This prevents these user-threads from also
     being scheduled as if they are high fixed-priority kernel threads.
   - Restore the setting of lowpri in tdq_choose().  It has to be either here
     or in sched_switch().  I accidentally removed it from both places.
