  Modified files:
    sys/kern             sched_ule.c 
  Log:
   - Add an implementation of sched_preempt() that avoids excessive IPIs.
   - Normalize the preemption/ipi setting code by introducing sched_shouldpreempt()
     so the logical is identical and not repeated between tdq_notify() and
     sched_setpreempt().
   - In tdq_notify() don't set NEEDRESCHED as we may not actually own the thread lock
     this could have caused us to lose td_flags settings.
   - Garbage collect some tunables that are no longer relevant.
