Synchronously sets up a D-Bus connection for exchanging D-Bus messages with the end represented by stream. If stream is a GSocketConnection, then the corresponding GSocket will be put into non-blocking mode. The D-Bus connection will interact with stream from a worker thread. As a result, the caller should not interact with stream after this method has been called, except by calling g_object_unref() on it. If observer is not NULL it may be used to control the authentication process. This is a synchronous failable constructor. See g_dbus_connection_new() for the asynchronous version. Since 2.26
