It's just a matter of fixing the vapis so that valac knows that
ownership is transferred and so no need to unref. You only need to add
owned to the declaration : public void add (owned Stk.Widget w);
If you're generating the vapi using vala-gen-introspect/vapigen, you
need to add a "transfer-ownership" annotation (not sure about the
spelling, check other metadata) to the .metadata file.
