John Baldwin d30d1cdee6 - Autogenerate a menu containing a list of countries and keymaps supported
by syscons.
- If we are running as init, popup the country menu before the main menu.
  If a non-default country is chosen, then a second menu is brought up
  to let the user choose a keymap.  By default the default keymap for
  the country that was selected is highlighted.  If the user chooses the
  default country, then the default keymap is just assumed and the user
  is not presented with the keymap menu.  Currently the default country
  is set to "United States" except for PC98 which assumes "Japan".
