Samuel Thibault 459a707ecc curses: support wide input
This makes use of wide curses functions instead of 8bit functions. This
allows to type e.g. accented letters.

Unfortunately, key codes are then returned with values that could be
confused with wide characters by ncurses, so we need to add a maybe_keycode
variable to know whether the returned value is a key code or a character
(curses with wide support), or possibly both (curses without wide support).

The translation tables thus also need to be separated into key code
translation and character translation.  The curses2foo helper makes it easier
to use them.
