Modified Files:
        src/sys/kern: kern_event.c

Log Message:
- Rename kqueue_misc_lock -> kqueue_timer_lock, since EVFILT_TIMER is
  now its only user.  Also initialize it as IPL_SOFTCLOCK; there is no
  practical difference in how it operates (it is still an adaptive lock),
  but this serves as a visual reminder that we are interlocking against
  a callout.
- Add some comments that describe why we don't need to hold kqueue_timer_lock
  when detaching an EVFILT_TIMER due to guarantees made by callout_halt().
- Mark timer_filtops as MPSAFE.
