As I said, I don't know whether its needed, but judging by James'
response, its going to be needed for a regular FC installation.

Its not needed today of course, so the attached patch changes it
to depend on NETFILTER_ADVANCED and removes the default.

I think I'll just change all the help texts for options having
different defaults with NETFILTER_ADVANCED=n to say "If unsure,
choose the default" to remove the contradictions we'd otherwise
always have.
