a5cc24440b The devices that supported EVFILT_NETDEV kqueue filters were removed in
r195175.  Remove all definitions, documentation, and usage.

fifo_misc.c:
	Remove all kqueue tests as fifo_io.c performs all those that
	would have remained.

95d4e7d075 Add EV_RECEIPT to kevents.
EV_RECEIPT is useful to disambiguating error conditions when multiple
events structures are passed to kevent(2).  The error code is returned
in the data field and EV_ERROR is set.

a386443e51 Add the EV_DISPATCH flag to kevents.
When the EV_DISPATCH flag is used the event source will be disabled
immediately after the delivery of an event.   This is similar to the
EV_ONESHOT flag but it doesn't delete the event.

7cb0718a03 Add EVFILT_USER to kevents.
Add user events support to kernel events which are not associated with any
kernel mechanism but are triggered by user level code.  This is useful for
adding user level events to an event handler that may also be monitoring
kernel events.

369cab6800 Eliminate the original method of requesting notification of aio_read(2) and
aio_write(2) completion through kevent(2).  This method does not work on
64-bit architectures.  It was deprecated in FreeBSD 4.4.  See revisions
1.87 and 1.70.2.7.

Change aio_physwakeup() to call psignal(9) directly rather than indirectly
through a timeout(9).  Discussed with: bde

Correct a bug introduced in revision 1.65 that could result in premature
delivery of a signal if an lio_listio(2) consisted of a mixture of
direct/raw and queued I/O operations.  Observed by: tegge

Eliminate a field from struct kaioinfo that is now unused.
