+ * 12-06-2013	Mark Riddoch		Move mysql_send_ok and MySQLSendHandshake
+ *					to use the new buffer management scheme
+ * 13-06-2013	Massimiliano Pinto	Added mysql_authentication check
+ * 14-06-2013	Massimiliano Pinto	gw_mysql_do_authentication puts user, db, and client_sha1 in the
+					(MYSQL_session *) session->data of client DCB.
+					gw_mysql_connect can now access this session->data for
