* 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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8612 a1c6a512-1295-4272-9138-f99709370657
