* dbus/dbus-bus.c
	(internal_bus_get): only weak ref the connection; this means
	_dbus_bus_notify_shared_connection_disconnected_unlocked can be
	called safely in any context
	(_dbus_bus_notify_shared_connection_disconnected_unlocked): don't
	unref

	* dbus/dbus-connection.c
	(_dbus_connection_get_dispatch_status_unlocked): move
	_dbus_bus_notify_shared_connection_disconnected_unlocked here
	when queuing Disconnected instead of when the Disconnected message
	arrives, so dbus_bus_get() won't return closed connections.
