Michael Bridgen cb05e886a8 Removed duplicate check for rDNS domain 
There's no need to check whether the queried address is a subdomain of
in-addr.arpa, since this handler is registered with the muxer under
that domain anyway.

(Also, remove a magic number)

Michael Bridgen 156314a802 Complete multicast requests on first response 
This is the simplest thing that works, is consistent with what happens
if there's a local answer, and avoids having all multicast requests
last 250ms or more.

Since we're no longer waiting *at least* the timeout period, I've
bumped the multicast response timeout up to half a second.

There was also a bug whereby the query would be entered into the
inflight map even if the socket write had failed (and the channel had
been closed).

Michael Bridgen 0615d122e9 Made zone return errors and http idempotent 
The Zone DB tells you if you have a duplicate or missing record, but
the HTTP server smoothes these over.

Michael Bridgen d3d07deec6 Changed local domain handling 
1. The local domain is now ".weave.local", which is safer from TLD

 ignore it
