Extend kqueue interface with EVFILT_EXCEPT filter.
This filter, already implemented in macOS and Dragonfly BSD, returns
exceptional conditions like the reception of out-of-band data.
The functionnality is similar to poll(2)'s POLLPRI & POLLRDBAND and
it can be used by the kqfilter-based poll & select implementation.
