We used 16-bit variables to store the 'character code' everywhere but
this won't let us represent anything beyond U+FFFF.
This patch changes those variables to a custom type that can be 32 or 16
bits depending on the build, and adjusts numerous internal APIs and
datastructures to match. This includes:
* utf8decode() and friends
* font manipulation, caching, rendering, and generation
* on-screen keyboard
* FAT filesystem (parsing and generating utf16 LFNs)
* WIN32 simulator platform code
Note that this patch doesn't _enable_ >16bit unicode support; a followup
patch will turn that on for appropriate targets.
Appears to work on:
* hosted linux, native, linux simulator in both 16/32-bit modes.
Needs testing on:
* windows and macos simulator (16bit+32bit)

Known bugs:
* Native players in 32-bit unicode mode generate mangled filename
entries if they include UTF16 surrogate codepoints. Root cause
is unclear, and may reside in core dircache code.
Needs testing on:
* windows simulator (16bit+32bit)

Note: I left behind lcd_bitmap in features.txt, because removing it
would require considerable work in the manual and the translations.

rb core allows you to load custom keyboard layouts
this patch adds the ability to load a keyboard layout in a buffer
the custom layout is temporary and does not overwrite the current layout
use like so:
unsigned short kbd[64];
unsigned short *kbd_p = kbd;
if (!kbd_create_layout("ABCD1234\n", kbd, sizeof(kbd)))
kbd_p = NULL;
rb->kbd_input(buf,sizeof(buf), kbd_p);
