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.

99a0598c28 Major peakmeter rework: * Changed set/get functions for dbfs mode to bool type. * Removed performance setting, leaving (slightly adapted) high performance mode only. * Refresh rate is always 20 Hz now. * Readout doesn't do an extra (hidden) peek, should allow for slightly better clip detection. * Brought back high performance peakmeter for recording. Peakmeter stops hogging the CPU when the disk is spinning; this is enough to avoid the performance problem when saving data. * Optimisations, code cleanup and code policeing. * (iriver) Reduced CPU load of peakmeter by not calculating excessive overlaps. ** Bumped config block version, so save your settings before upgrading.

27c83252e2 The peak meter on iRiver didn't look right to me and the code seemed to be 
making it a lot more complicated that it needed to be, so I threw in some new
code. This should be easy to adjust for different CPU loads, and I set it up
to use a little less than what was there. If this causes any trouble, please
roll it back.
