Require the address and port information for the target (non initiating) side to be populated when a flow enters TGT state. Implement that for TCP and ICMP. For now this leaves some information redundantly recorded in both generic and type specific fields. We'll fix that in later patches. For TCP we now use the information from the flow to construct the destination socket address in both tcp_conn_from_tap() and tcp_splice_connect().
