[PATCH] Add serdisplib driver

This patch adds a serdisplib driver for the serdisplib library
(http://serdisplib.sf.net) that is used for low-level accessing of dot-matrix
devices (i.e. such displays that are drived by pixel and not by characters
unlike HD44780, for example).

I know there's already glcdlib. But that approach has several disadvantages:

  o Unnecessary library dependencies.
  o Complicated installation, i.e. you have to edit two configuration files.
  o Too much redraws. In fact, that was the reason for me to write this
    driver because my ctinclud display (http://www.ct-maeusekino.de) was quite
    unusable with the glcdlib driver. The problem is simply that lcdproc
    redraws the whole screen each second and it's the task of the driver
    to not to redraw it in reality. The problem is now that the glcdproc
    driver only has the view of characters, and cannot decide which pixels it
    actually has to redraw. And graphlcd which has the per-pixel view doesn't
    do that "caching" and simply redraws all. Of course, that _can_
    be changed in graphlcd, but I'm sure that leads to endless discussions and
    because I didn't like the glcdlib -> graphlcd -> serdisplib approach
    anyway, I decided to write that driver.

Some important design decisions:

 o The driver is split into lcdgraphic.c and serdisplib.c. All function that
   do the character -> pixel "rendering" are split out into lcdgraphic.c,
   so it would be possible to write another low-level driver that uses that
   function. However, in normal cases it makes more sense to add that part to
   serdisplib.
 o It only requires FreeType (http://freetype.sf.net) for font rendering.
   That's no new real dependency because in almost all cases, graphlcd was
   compiled with FreeType support.
 o Only mono space fonts are supported.
 o The driver implements symbols (arrow, etc.) using Unicode characters of the
   font. (The recommended font is Andale Mono which is available for free
   from http://corefonts.sf.net)
 o Works on i686 and x86_64.

Please review. The patch is against 0.5.2. If you consider to add this into
CVS, I'll provide documentation. And this time, I'll provide the documentation
in time unlike with the ula200 driver. ;-)
