input: allow unicode keys and reassign internal key codes

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.
