	* dbus/dbus-glib-lowlevel.h, glib/dbus-gobject.c: Patch from Rob
	Taylor to add two methods, dbus_g_method_return_get_reply and
	dbus_g_method_return_send_reply, to allow you to get the reply
	message from a DBusGMethodInvocation, append arbitrary stuff to it,
	and send it. The GLib bindings can't marshal a return value of
	something like a(s) if the array is empty - ultimately they should be
	made to heed the signature of the out arguments as the Python bindings
	now can, but this is a workable interim solution which might have
	other applications.
