I don't really know. There is only one entry point to the functionallity
(dbus_connection_setup_with_g_main), so as long as you get *one* of the
linked in implementations it should work. And there is no way to mix the
version in different calls, since there is only one call.

But there might still be some issue with symbol conflicts.

At the very least we don't want to export the symbols from the
library .so file.
