* xmenu.c (digest_single_submenu): Set lname and lkey in widget_value

instead of name and key.
(update_submenu_strings): New function.
(set_frame_menubar): Remove call to inhibit_garbage_collection,
call update_submenu_strings.  Call ENCODE_MENU_STRING for top level
menu names.

* gtkutil.h (_widget_value): Added lname and lkey.
