Subject: [PATCH] Changed private data for jabber connection to include SASL
 context

The private hook data for jabber connections, which consisted solely
of the iksemel (XML) parser, now includes GNU SASL context and
client/server sessions. Functions for creating and destroying the data
are provided.
