As you pondered in irc, policing the code has the advantage of making it
more portable.

I've already fixed all the obvious problems gcc found (i.e. testing if a
var of type "char" was < 0), but I think I would prefer to avoid adding
-fsigned-char unless we run into problems in the future.

Most of the codecs use the int8_t and uint8_t types - which are now
explicitly defined to be signed or unsigned char respectively.

For people who haven't been following this, the C specification says
that plain "char" is either signed or unsigned depending on the
platform. Up to now, all Rockbox platforms (including x86 for the sims)
have had signed chars - but chars are unsigned on ARM.

Dave.
