We did this once for GtkFileSystemIface and its is_finished_loading
method.  The implementation of gtk_file_folder_is_finished_loading has
this:

  if (!GTK_FILE_FOLDER_GET_IFACE (folder)->is_finished_loading)
    return TRUE;
  else
    return GTK_FILE_FOLDER_GET_IFACE (folder)->is_finished_loading (folder);

We can do the same thing for new methods.

So, we have these issues:

1. Comparing paths in a filesystem-specific way.

2. Getting special folders (Desktop, etc.).

(1) is easy, as we just need to add a vmethod to the Iface.

For (2) we already have a little bunch of g_get_foo_dir() functions in
Glib, and perhaps we don't want to just pile in more functions to get
the Desktop, Documents, etc.  This also ties in with the discussion in
desktop-devel-list about how to translate directory names in Unix.
