  Log:
  - Protect the callout wheel with a separate spin mutex, callout_lock.
  - Use the mutex in hardclock to ensure no races between it and
    softclock.
  - Make softclock be INTR_MPSAFE and provide a flag,
    CALLOUT_MPSAFE, which specifies that a callout handler does not
    need giant.  There is still no way to set this flag when
    regstering a callout.
