to TAILQs. Fix places which referenced these for no good reason
that I can see (the references remain, but were fixed to compile
again; they are still questionable).
and fix some bugs..
also fix a bug in aarp.c that didn't take netranges into account.
default routes now work with appletalk, which is a poor-man's
way of being able to access netranges if you only have one network :)
Hopefully the full netranges fix will happen soon.
Kernel Appletalk protocol support
both CAP and netatalk can make use of this..
still needs some owrk but it seemd the right tiime to commit it
so other can experiment.
