* for the component handshake as defined in XEP-0114.
* The domain and port to connect to must be provided in this case as the JID
* provided to the call serves as component identifier to the server and is
* not subject to DNS resolution.
*
* @param conn a Strophe connection object
* @param server a string with domain to use directly as the domain can't be
* extracted from the component name/JID. If this is not set, the call
* will fail.
* @param port an integer port number to use to connect to server expecting
* an external component. If this is 0, the port 5347 will be assumed.
* @param callback a xmpp_conn_handler callback function that will receive
* notifications of connection status
* @param userdata an opaque data pointer that will be passed to the callback
*
* @return XMPP_EOK (0) on success or a number less than 0 on failure
