MFC: We couldn't specify the rule for filtering tunnel traffic since an
IPv6 support was committed:

- Stop treating `ip' and `ipv6' as special in `proto' option as they
  conflict with /etc/protocols.

- Disuse `ipv4' in `proto' option as it is corresponding to `ipv6'.

- When protocol is specified as numeric, treat it as it is even it is
  41 (ipv6).

- Allow zero for protocol as it is valid number of `ip'.

	sbin/ipfw/ipfw.8:	1.180
	src/sbin/ipfw/ipfw2.c:	1.80
