c2617dc4ed Diacritic display enhancements
- Use the fact that unicode code currently does not support chars above 0xffff
  (see utf8decode()), and change diacritic database's char code type to
  unsigned short from int. Also comment out database entries above unsupported
  range.

- Use const when possible.

- Iterate over buffer using the buffer's pointer, thus avoiding usage of some
  variables, and avoiding multiple access to the same array item.

7682cb5ca8 FS#10720 - Support for displaying diacritic characters
This commit corrects the display of diacritic characters, which exist in many
languages. Hopefully, it will make Rockbox much more usable for users of these
languages.

Diacritic information (which used to decide whether a given character is
diacritic or not) is taken from the Unicode Standard, Version 5.2.

This feature does not affect drawing performance much, as the diacritic
database is cached (simple MRU mechanism).

There may be room for further performance, footprint, and
code-reuse wise improvements, that could be worked on in the future.
