Subject: Bug 15571: Clean up GUID-less connections correctly (Scott James
 Remnant)

	* dbus/dbus-connection.c (connection_forget_shared_unlocked):
 	Remove shared connections which lack a GUID from the list that
 	caches those, otherwise references to them will remain after
 	they have been freed.
	* test/name-test/test-privserver-client.c: Update test to
	try GUID-less connections too.
