Menus are composed of items. Each item has a key used to identify it in
the menu, and an opaque pointer to data controlled by the consumer.
If you want to show a menu, instead starting the shell, define
CONFIG_MENU_SHOW. You have to code the int menu_show(int bootdelay)
function, which handle your menu. This function returns the remaining
bootdelay.
