413da2a3d9 Rework PCM buffer 
* Linked list instead of static array buffer pointers
* Variable sized chunks
* Improved mix handling
* Reduction in duplicated code
* Reduced IRAM usage w/o sacrificing performance
* Converted to almost entirely unsigned math
* Add pause function to reduce pcm_* exposure to playback.

This WILL break playback on the iPod until linuxstb makes a followup commit.

c52f7f1b5e iRiver: Fixed broken items skipping on playlist: Now skipping and 
marking them as bad instead of deleting the entries from playlist.
Faster buffered track skipping and preventing glitches from previous
tracks (still something might occur though, please report them).

90161c92dd It's now possible to select the crossfading mode: "Off, Crossfade, 
Mix". If set to mix, no fading is applied but tracks are mixed up.
