audiolib: Introduce support for PlayStation CD-XA audio, a simple ADPCM format.

Browse source 
It's functional, but due to the odd 37.8 KHz nature of the format, I will need to add a resampler to the audiolib to prevent the aliasing artifacts that occur at present. I also hear clicks/pops every so often, but I do not know if a resampler would fix these as well or if they are a separate problem.

Note that you cannot directly use the four XA files on the Total Meltdown disc because they each contain eight songs. They would need to be split using a utility I wrote that is outside the scope of this SVN.
