ab1861a3c2 iRiver/iAudio: Added audio_set_recording gain and sound_default to plugin API. Simplified plugin recording by target/-ing some audio functions. UDA1380 records with WSPLL as a result.

fbac4f8444 Audio bugfixes. Should wait for voice codec to reload before returning buffer when stealing voice. Certain variables that get or may get used during an IRQ should be declared 'volatile'.

0f5cb94aa4 Big Patch adds primarily: Samplerate and format selection to recording for SWCODEC. Supprort for samplerates changing in playback (just goes with the recording part inseparably). Samplerates to all encoders. Encoders can be configured individually on a menu specific to the encoder in the recording menu. File creation is delayed until flush time to reduce spinups when splitting. Misc: statusbar icons for numbers are individual digits to display any number. Audio buffer was rearranged to maximize memory available to recording and properly reinitialized when trashed. ColdFire PCM stuff moved to target tree to avoid a complicated mess when adding samplerate switching. Some needed API changes and to neaten up growing gap between hardware and software codecs.

33a62e8a8e More work on swcodec. No significant pcmbuf functions are called from the audio thread now. Do not be surprised if seek or skip behavior gets weird after this, but it Works for Me (TM), and is a significant step in the right direction.

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.
