[PATCH 13/15] New config variable CONFIG_MENU

[Pali Rohár]

 * If defined CONFIG_MENU and CONFIG_MENUKEY to 0 run env "menu_cmd" if key any pressed
 * If defined CONFIG_MENU and other CONFIG_MENUKEY run env "menu_cmd" if key pressed is save as CONFIG_MENUKEY
 * If defined CONFIG_MENU and not CONFIG_MENUKEY run env "menu_cmd" always
 * If not defined CONFIG_MENU do nothing
 * CONFIG_MENUKEY working only if defined CONFIG_MENU and CONFIG_BOOTDELAY >= 0
