Migrate from :sys:started events to dbus owner signals.

Migrate from :sys:started events to dbus owner signals.

[Dimitri John Ledkov (xnox)]

When system upstart goes away, :sys:started/stopped/starting/stopping events will go away.

One option is to introduce a user session event bridge which will relay similar events from systemd. I have a working prototype for that, however incomplete information is exposed by systemd at the moment.

Another option is to key onto approximately equivalent events which are already available.

This is a master bug to track all users and port them.
