Cloning the source file is a bad idea. If it's not possible to implement
it all inside GSocket (or if it would add a ton of kdbus-specific
stuff), then it should be done as a subclass of GSocket.

You don't want to do anything with GSocketClient; that's just a helper
for creating TCP connections.

Depending on exactly what you need (I'm not really familiar with kdbus),
it might be that GSocketConnection isn't a good match, and so making a
new "GKdbusConnection" or something might make sense. There is also a
bug open about adding control message support to the existing
GSocketConnection (https://bugzilla.gnome.org/show_bug.cgi?id=618556,
although the source code link from there is long-dead).
