Implement eventfd_ioctl() and handle FIONBIO so that fcntl(O_NONBLOCK)
works.  While here, also implement FIONREAD and FIONWRITE, and document
why we don't implement FIONSPACE.

Also implement FIONBIO and FIONREAD for in timerfd_ioctl() (for the same
reason).

Fix "restart" semantics -- restart is terminal, so don't clear the
condition when previous waiters have drained.  ("restart" is a bad
name for that this function does, fwiw.)

This should address a kernel assertion failure reported by Chavdar Ivanov
on current-users.

Change the kqueue filterops::f_isfd field to filterops::f_flags, and
define a flag FILTEROP_ISFD that has the meaning of the prior f_isfd.
Field and flag name aligned with OpenBSD.

This does not constitute a functional or ABI change, as the field location
and size, and the value placed in that field, are the same as the previous
code, but we're bumping __NetBSD_Version__ so 3rd-party module source code
can adapt, as needed.
