/** 
 * @brief Allows to start a MQTT server on the provided local host
 * address and port running MQTT over WebSocket protocol.
 *
 * <b>Important note:</b> you must call to \ref myqtt_storage_set_path
 * to define the path first before creating any listener. This is
 * because creating a listener activates all server side code which
 * among other things includes the storage loading (client
 * subscriptions, offline publishing, etc). In the case direction,
 * once the storage path is loaded it cannot be changed after
 * restarting the particular context used in this operation (\ref
 * MyQttCtx).
 *
 * @param ctx The context where the operation takes place.
 *
 * @param listener The webSocket listener connection created on top of which MQTT over WebSocket is expected.
 *
 * @param opts Optional connection options to modify default behaviour.
 *
 * @param on_ready Optional on ready notification handler that gets
 * called when the listener is created or a failure was
 * found. Providing this handler makes this function to not block the
 * caller.
 *
 * @param user_data Optional user defined pointer that is passed into
 * the on_ready function (in the case the former is defined too).
 *
 * See \ref myqtt_listener_new for more information.
 *
 * @return A newly created connection listener reference (\ref
 * MyQttConn). Use \ref myqtt_conn_is_ok to check listener was created
 * without errors.
