Support mDns Multipacket Known-Answer Suppression

When a query packet is truncated, the responder should defer
the generation of a response until all packets have been received
and processed. If an answer present in the query packet's answer
section also appears in the responder's response, and the
known-answer's TTL exceeds half of the original TTL, suppress
the corresponding response.
