Thank you for these comments Neil.
This is a small part of missing pieces of IPv6 support for the server.
It deals with the ip_map caching code part.
It changes the ip_map structure to be able to store INET6 addresses.
It adds also the changes in address hashing, and mapping to test it with INET
addresses.

The code canonicalizes IPv4 addresses in several places. Is there
already a generic function defined somewhere to do this? If not, it
might make sense to add one.
