[NETFILTER]: nf_conntrack_expect: support inactive expectations
This is useful for the SIP helper and signalling expectations. We don't want to create a full-blown expectation with a wildcard as source based on a single UDP packet, but need to know the final port anyways. With inactive expectations we can register the expectation and reserve the tuple, but wait for confirmation from the registrar before activating it.
