    kernel - Make filters able to be marked MPSAFE
    
    * Change struct filterops f_isfd field to f_flags, taking FILTEROP_ISFD and/or
      FILTEROP_MPSAFE.
    
    * Convert all existing filter definitions to use new flags.
    
    * Create filter_attach/detach/event wrapper functions for calling through the
      struct filterops vector that grab the MPLOCK as necessary.
    
    * kern_event() uses kq->kq_count to determine whether or not to sleep,
      kqueue_scan() removes events from the TAILQ and can possibly sleep, releasing
      the global kq token, before updating kq->kq_count.
