Matthias Clasen dd1c0c0b22 treelistmodel: Make constructor transfer full
Make gtk_tree_list_model_new() take the root model
as first argument, and make it transfer full, for
consistency with other wrapping list constructors.

Update all callers.

Still missing here: Make the model property writable,
and allow passing NULL in the constructor.
