If the GDBusObjectManagerClient doesn't get a name owner during its lifetime,
`on_control_proxy_g_signal' will never be connected to any signal, so we
shouldn't dump any warning in that case.

Otherwise we might collide with an interface called Connection.

This is for the same reason that GDBusProxy has its properties
prefixed with g-.

This is needed because the proxy may need to update its internal state
which a signal handler connected to the manager may rely on.

To help cross compilation, don't use glib-genmarshal in our
build. This is easy now that we have g_cclosure_marshal_generic().
In gobject/, add gmarshal.[ch] to git (making the existing entry
points stubs).
In gio/, simply switch to using g_cclosure_marshal_generic().
