Add method to update the client routes. Add an event when the client routes changed. Listen for route_changed events on clients that do a subscribe on the stream-restore extension. Emit an EVENT when the routes change. This keeps the system notifications volumes in sync between gnome-control center and pavucontrol and probably in other tools as well. Fixes #3805
