Reviewed by Chris Dumez.

Store the registered mdns names in a HashSet.
In case of a mDNS resolution, we check the hashset and if there is a match, we use the current local address directly.
This ensures that mDNS resolution with Safari works even if mDNS registration fails.
We add a mechanism to remove the mdns names from the HashSet whenever the document goes away, to keep the same mDNS lifetime as before.
