Support for this is rather simple, and some combinations of modifiers
and keys don't work. For example, Ctrl+Alt+character is not supported,
because Windows doesn't emit a WM_CHAR in this case.
Also add support for the pause and print screen keys. Remove the
pointless KEY_CTRL translation. Remove KEY_CTRL altogether, because it
was not clear what it was actually supposed to mean.
This moves all key codes above the highest valid unicode code point (which
is 0x10FFFF). All key codes below MP_KEY_BASE now directly map to unicode.
Configuration files (input.conf) can contain unicode characters in UTF-8
to map non-ASCII characters/keys.
This shouldn't change anything user visible, except that "direct key codes"
(as used in input.conf) will change their meaning.
Increase the number of supported mouse buttons from 10 to 20. There
really seem to be input devices with at least 12.

Move the definitions of all special key codes (those not passed by
ASCII value) to input/keycodes.h. Before they were spread between
osdep/keycodes.h, input/joystick.h, input/mouse.h and input/ar.h, plus
some special values in input.h. This was especially inconvenient as
the codes had to be coordinated to not conflict between the files.
The change requires a bit of ugliness as appleir.c includes
<linux/input.h> which contains various conflicting KEY_* definitions.
Work around this by adding a special preprocessor variable which can
be used to avoid defining these in keycodes.h.
