buffet: Add correct handling of XMPP IQ stanzas

Implemented a more intelligent handling of IQ requests and responses.

Each time an IQ request is sent, a new unique request ID is generated
and then a response with the same ID is expected. If no reponse is
received within a timeout interval (of 30 seconds) a timeout callback
is called allowing the caller to handle this event correctly.

Changed the XMPP connection handshake implementation which used some
of IQ stanza exchange with the server to use the new IqStanzaHandler
class.
