(command_loop_1): Set FRAME_MENU_BAR_ITEMS here.

Browse source 
(menu_bar_items): Reverse the list when done.

(command_loop_1): Typo calling Qrecompute_lucid_menubar.
(read_key_sequence): Likewise.  Also fix call to Vrun_hooks.

(kbd_buffer_get_event): Handle selection_clear_event
and selection_request_event events.

(read_key_sequence): Support Vcurrent_menubar
and Qactivate_menubar_hook.  Call Qrecompute_lucid_menubar.
(syms_of_keyboard): Set up Vcurrent_menubar, Vprevious_lucid_menubar,
Qactivate_menubar_hook, and Qrecompute_lucid_menubar.
