Checking a service without activating it

[Julien PUYDT]

Hi,

I saw there was a thread on getting the _list_ of all services, not only
those running.

But I would like to ask about a more specific question to ask to the
(d)bus: "Is org.example.foo_service available to you?". I thought I
could perhaps do it using some kind of DONT_REALLY_ACTIVATE_IT flag to
dbus_bus_activate_service, but:
1) those flags aren't documented ;
2) looking at the source, they seem to be ignored anyway.

Any idea?
