dns: handle multiple replies for single requests
The world is a mess. A single DNS request may yield multiple, subtly different responses; all with the same DNS protocol-level ID. Last response wins in terms of what ends up in the cache. First response wins in terms of the response sent to the client. Hard to do otherwise since we have no clue that more than one answer will be forthcoming.
