Add a way to obtain the DBusConnection* pointer from a QDBusConnection

This is internal API and the behaviour may change without notice. In
the future, I could use a different implementation without libdbus-1,
so this pointer may be something different. The use of DBusConnection
is also entirely implementation-defined, so keeping this connection
around is entirely unsupported.

You have been warned.
