Handle IP address information requests

This adds the last required bit of the KVP interface: providing
IP address info back to the Host on request.  Normally the Host
is not specifying the address family and in this case we prefer
to report back the first IPv4 address we can find and resort to
IPv6 only when no IPv4 addresses are configured.

It also appears that the 5th version of the message format is
not publicly documented yet and IP address information request
messages differ from the 4th version so we have to take the
negotiated protocol version down a notch.
