[NETFILTER]: nf_conntrack: automatic helper assignment for expectations
Some helpers (namely H.323) manually assign further helpers to expected connections. This is not possible with nf_conntrack anymore since we need to know whether a helper is used at allocation time. Handle the helper assignment centrally, which allows to perform the correct allocation and as a nice side effect eliminates the need for the H.323 helper to fiddle with nf_conntrack_lock. Mid term the allocation scheme really needs to be redesigned since we do both the helper and expectation lookup _twice_ for every new connection.
