We should ensure that we send the announce both via IPv6 and IPv4,
and to be safe we also add the "ipv6=" and "ipv4=" parameters, if
we already have them. Our global IPv6 address is computed for the
LTEP handshake, so this comes for free. Our public IPv4 address
may have been returned from a previous announce and stored in the
session.

longer need to compute the global IPv4 and IPv6 addresses.
