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.

.Sh BUGS
The
.Dv EVFILT_NETDEV
filter is currently only implemented for devices that use the
.Xr miibus 4
driver for LINKUP and LINKDOWN operations.
Therefore, it will not work with many non-ethernet devices.
.Pp
The
.Fa timeout
value is limited to 24 hours; longer timeouts will be silently
reinterpreted as 24 hours.
