CVE-2013-1431: respect tls-required flag on legacy Jabber servers
CVE-2013-1431: respect tls-required flag on legacy Jabber servers

It's checked elsewhere for XMPP 1.0 servers, which can either
use "old SSL" or perform STARTTLS. Legacy Jabber can only use
"old SSL", which is similar to https - connect to a separate port,
typically 5223, and start speaking SSL - so if the connection was
ever going to be encrypted, by this point it already would be.
