79acfc497b - Add the new sched_pctcpu() function to the sched_* api.
- Provide a routine in sched_4bsd to add this functionality.
 - Use sched_pctcpu() in kern_proc, which is the one place outside of
   sched_4bsd where the old pctcpu value was accessed directly.

- Create a new callout for lbolt and move it out of schedcpu().  This is not
