Patch to implement a CAF parser

CAF is Apple's core audio format.
https://developer.apple.com/library/mac/#documentation/MusicAudio/Reference/CAFSpec/CAF_overview/CAF_overview.html#//apple_ref/doc/uid/TP40001862-CH209-TPXREF101

It is of course very common in the Apple world.
It can be seen as an enhanced WAV format.
Unlike WAV it has for example no limitation to the file length.
It is therefor also useful to use it on other platforms.
