HEADS UP: rc.firewall and rc.firewall6 were unified

[Hajimu UMEMOTO]

Hi,

It was hard to co-exist an IPv4 firewall rule and an IPv6 firewall
rule in the past.  By revision 206382, The rc.firewall and
rc.firewall6 were unified, and rc.firewall6 and rc.d/ip6fw were
removed.
According to the removal of rc.d/ip6fw, ipv6_firewall_* rc variables
are obsoleted.  Instead, the following new rc variables are added to
rc.d/ipfw:

	firewall_client_net_ipv6, firewall_simple_iif_ipv6,
	firewall_simple_inet_ipv6, firewall_simple_oif_ipv6,
	firewall_simple_onet_ipv6, firewall_trusted_ipv6

The meanings correspond to the relevant IPv4 variables.

Sincerely,
