* generator/ReturnValue.cs: use new ListPtrToArray marshaler for lists with known element types. * glib/Marshaller.cs: new ListPtrToArray marshaller with more aggressive list disposal. * gtk/Container.custom: remove manual Children impl. Use Children in GetEnumerator instead of pinvoking directly. * gtk/Gtk.metadata: remove hidden attr and add element type and owned for Container.GetChildren to generate it properly. svn path=/trunk/gtk-sharp/; revision=111173
