Pull up following revision(s) (requested by maya in ticket #1418):

        distrib/sets/lists/modules/mi: revision 1.127
        sys/modules/Makefile: revision 1.230
        sys/modules/filemon/Makefile: revision 1.4 (manually adjusted)
        sys/modules/Makefile: revision 1.229

Disable filemon.

It isn't suited for general use (that is, it poses security risks),
but the existence of the module means it is auto-loaded when /dev/filemon
is opened, which can be done by any user.

Thanks Ilja van Sprundel for the heads up.

 -

Continue to build the filemon module, but don't install it.  Hopefully
this will help us detect any additional bit-rot that might occur.

XXX It might be a good idea to modify the file permissions on /dev/filemon
XXX to prevent auto-loading of the driver module by non-privileged users.
