Added infrastructure to support more than 8 bit signed / unsigned RAW

mixers. Porters, beware, the default configuration is now 16 bit
stereo instead of 16 mono as before (I changed X11 and SDL but no
others).

I did not add support for any other format yet, I will let Endy do it
when he needs it :-)
