netfilter: ctnetlink: dump conntrack ID in event messages
Conntrack ID is not put (anymore ?) in event messages. This causes current ulogd2 code to fail because it uses the ID to build a hash in userspace. This hash is used to be able to output the starting time of a connection. Conntrack ID can be used in userspace application to maintain an easy match between kernel connections list and userspace one. It may worth to add it if there is no performance related issue.
