how to be notified when an application with dbus service lauchs or quits?

[Kaustubh Atrawalkar]

If the target application is acquiring a dbus service then at least you can
connect to NameOwnerChanged Signal and keep a track of the service name
registered from which at least u can find the executable name by some hacks.
(i can provide u those if needed)
