[NETFILTER]: connection tracking event notifiers
This adds a notifier chain based event mechanism for ip_conntrack state
changes. As opposed to the previous implementations in patch-o-matic, we
do no longer need a field in the skb to achieve this.
Thanks to the valuable input from Patrick McHardy and Rusty on the idea
of a per_cpu implementation.
