GtkTreeStore doesn't fully release

[Emmanuel Briot <briot act-europe fr>]

While running my application with "GOBJECTS_DEBUG=objects", I saw the following
problem in GtkTreeStore:

It seems that the GtkTreeStore widget doesn't properly release its contents on
finalize.

Only the root node is currently freed, whereas with the following patch the
whole tree is freed:

- static void
+ static gint
  node_free (GNode *node, gpointer data)
  {
    _gtk_tree_data_list_free (node->data, (GType*)data);
+  return FALSE;
  }

  static void
  gtk_tree_store_finalize (GObject *object)
  {
    GtkTreeStore *tree_store = GTK_TREE_STORE (object);

-  g_node_children_foreach (tree_store->root, G_TRAVERSE_ALL, node_free, tree_store->column_headers);
+  g_node_traverse (tree_store->root, G_POST_ORDER, G_TRAVERSE_ALL, -1, node_free, tree_store->column_headers);
