  Modified files:
    sys/kern             sched_ule.c 
   - Get rid of the unused DIDRUN flag.  This was really only present to
     support sched_4bsd.
   - Rename the KTR level for non schedgraph parsed events.  They take event
     space from things we'd like to graph.
   - Reset our slice value after we sleep.  The slice is simply there to
     prevent starvation among equal priorities.  A thread which had almost
     exhausted it's slice and then slept doesn't need to be rescheduled a
     tick after it wakes up.
   - Set the maximum slice value to a more conservative 100ms now that it is
     more accurately enforced.
