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 (KEY_ENTER is 13, carriage return). 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.

Parts of the bstr functions taken from libavutil's GET_UTF8 and
slightly modified.
