DNS SRV support

Recently the jabber.org IM service came under attack, and as a
preventive measure we made some changes to our DNS SRV records: the
attacker went after the IP address of our primary hostname so we set
up a secondary hostname at a different IP address; more recently we
have continued to list the A record for jabber.org as the IP address
that came under attack while listing different IP addresses in our SRV
records. One side effect has been that IM clients without proper DNS
SRV support (see section 3.2 of RFC 6120) have been unable to connect
to jabber.org. As I understand it, Pidgin is one such client (the
workaround is to "hardcode" one of the machine hostnames as the
connection address, which works but is more brittle since we might
change those hostnames, e.g. when we set up a new machine in the near
future). Is this a known issue in Pidgin or libpurple? If not, I'll
submit a feature request.

Thanks!

Peter
