Commit 799bbdb50
split out the public Fdo notification service, so
that any app with permission to talk to org.freedesktop.Notifications
will in fact be limited to that service.
To a somewhat lesser extent this applies to the org.gnome.ScreenSaver
service as well, which some applications still use instead of the
Inhibit portal.
