xdg-shell/toplevel: Chain multiple parent-child relationships
Change the semantics of xdg_toplevel.set_parent to allow chaining
multiple parent-child relationships together, while allowing
arbitrarily unmapping parents, while keeping what is left over of the
chain intact.
This makes things easier to manage when parent-child relationships
cross client borders, for example when using xdg_foreign.
