netfilter: nfnetlink_queue: allow to attach expectations to conntracks

Browse source

This patch adds the capability to attach expectations via nfnetlink_queue.
This is required by conntrack helpers that trigger expectations based on
the first packet seen like the TFTP and the DHCPv6 user-space helpers.
