Add support for line drawing characters and the alternate character set.
This enables using the ACS_ curses macros with libpayload. The translation from ACS_ macros (or characters with attribute A_ALTCHARSET) is done using one acs map for the video console, one for serial console (xterm/vt100/vt220), and one fallback, from which an ASCII substitute is taken if the device specific map doesn't contain an entry (ie NUL).
