b44c18ea9d Quick fix for crossfeed on iPod. Still needs optimization, but at least no 
more unpleasant surprises!

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.

df37db99ce Added Coldfire ASM optimised crossfeed function. Have not measured speed improvement, but it is faster. Also moved activation check for crossfeed out of function to avoid a function call if it's not activated.

abd9f83e92 Two new sections for IRAM usage: .irodata (selectable with the ICONST_ATTR attribute macro), allowing to put 'const' data into IRAM without causing a section type conflict, and .ibss (selectable with the IBSS_ATTR attribute macro) for uninitialised data. * Rockbox core: Adjusted the linker scripts and init code to not include the .ibss section in the binary, it is cleared instead. Saves ~500 bytes on archos and ~30KB on iriver. Codecs and plugins don't handle .ibss in a special way yet. * The init code properly handles empty sections now (except .stack, which should never be empty). * Unified the init code for SH1 and coldfire a bit.

Note that there is a small delay from leaving a setting until the change
can be heard (due to audio data buffering).
