(requested by christos in ticket #716).

- initialize kn_id
- in close, invalidate f_data and f_type early to prevent accidental re-use
- add a DIAGNOSTIC for when we use unsupported fd's and a KASSERT for f_event
  being NULL.

Return EOPNOTSUPP for fnullop_kqfilter to prevent registration of unsupported
fds. XXX: We should really fix the fd's to be supported in the future.
Unsupported fd's have a NULL f_event, so registering crashes the kernel with
a NULL function dereference of f_event.

mention that kevent returns now EOPNOTSUPP.

Move the references to PRs from code comments to the test description. Once
ATF has the ability to output the metadata in the HTML reports, it should be
easy to traverse between releng and gnats -reports via links.

Add a (skipped for now) test case for PR 46463

adapt to new reality

Add a test for adding an event to an unsupported fd.
