Asynchronously 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 gobject.object.ObjectG.unref on it.
If observer is not null it may be used to control the
authentication process.

When the operation is finished, callback will be invoked. You can then call gio.dbus_connection.DBusConnection.newFinish to get the result of the operation.
This is an asynchronous failable constructor. See gio.dbus_connection.DBusConnection.newSync for the synchronous version.
