The struct thread td_estcpu member is only used by the 4BSD scheduler.
Move it to the struct td_sched for 4BSD, removing always present
field, otherwise unused for ULE.
New scheduler method sched_estcpu() returns the estimation for
kinfo_proc consumption. As before, it always returns 0 for ULE.
Remove sched_tick() scheduler method, unused both by 4BSD and ULE.
Update locking comment for the 4BSD struct td_sched, copying it from
the same comment for ULE.
Spell MAXPRI as PRI_MAX_TIMESHARE in the 4BSD comment.
