        * gtk/gtkfilechooserdefault.c (create_path_bar): new function to
        consolidate creating the path_bar.
        (gtk_file_chooser_default_set_current_folder): no longer need to
        pass in the filesystem.

        * gtk/gtkpathbar.h: Removed unused set_pixbuf functions in favor
        of just setting the filesystem.

        * gtk/gtkpathbar.c (gtk_path_bar_finalize): Free root path and
        home_dir.
        (get_button_image): Add images to path_bar.
        (update_button_appearance): use images
        (make_directory_button): Clasify buttons based upon location.
        (_gtk_path_bar_set_path): no longer need a file-system.  Also, add
        rerooting, #135845, #135914

        * tests/testfilechooser.c: Fix reused error handling.
