- 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.

- Fix bug which cause wrong placement of characters in some specific conditions
- Fix multiple similar entries in cache
- Protect against negative x values passed to drawing function

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.

Move text-drawing code into firmware-drivers/lcd-bitmap-common.c, included by the various driver files.
Add new static function LCDFN(putsxyofs_style) to draw styled text, and use it in both LCDFN(puts_style_offset) and LCDFN(scroll_fn).
Merge lcd_gradient_rect functions, with new function containing simplified code for drawing one line of a multi-line gradient.
