netfilter: conntrack: move event caching to conntrack extension infrastructure
This patch reworks the per-cpu event caching to use the conntrack extension infrastructure. The main drawback is that we consume more memory per conntrack if event delivery is enabled. This patch is required by the reliable event delivery that follows to this patch. BTW, this patch allows you to enable/disable event delivery via /proc/sys/net/netfilter/nf_conntrack_events in runtime, although you can still disable event caching as compilation option.
