Add ip6tables support for IPv6 filtering

Browse Source 
This patch adds IPv6 filtering support for the following protocols:
- tcp-ipv6
- udp-ipv6
- udplite-ipv6
- esp-ipv6
- ah-ipv6
- sctp-ipv6
- all-ipv6
- icmpv6

Many of the IPv4 data structure could be re-used for IPv6 support.
Since ip6tables also supports pretty much the same command line parameters
as iptables does, also much of the code could be re-used and now
command lines are invoked with the ip(6)tables tool parameter passed
through the functions as a parameter.
