[NETFILTER]: Add iptables CONNMARK match+target
This is the first patch, adding something similar like nfmark, but on a per-conntrack (as opposed to per-skb) level. Very useful especially for asymmatric routing in combination with MASQUERADE, as often found on home DSL setups with dymamic IP address that also have e.g. a tunnel device with static IP.
