pulse-server: implement stream-restore EVENT

Browse source 
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
