af395f4db6 Do core interrupt masking in a less general fashion and save some instructions to decrease size and speed things up a little bit. Small fix to a few places where interrupts would get enabled again where they shouldn't have been (context switching calls when disabled).

2d48d0ffa6 Straighten out some audio path APIs and misc. audio stuff. Having recording is not a prerequisite to having input/output source selection which is probably most useful when adding a audio input features like FM to a new port without forcing recording to be implemented first.

633f388002 Coldfire targets: Shuffle IRQ levels around to have all interaction between low level audio function calls and DMA be atomic. Make recording and playback independently startable and stoppable so one can be running and not interfere with the other. All tests I can do at the moment check out ok (play, record, play+record, FM radio on iRivers, S/PDIF on H120 (w/running optical on/off), and on-the-fly samplerate changes). Recording tested for well over an hour run and no problems.

198772a6b2 iRiver H100 series: Catching up on old work. Use a better way to keep playback going when switching optical output. Doesn't mess with the DMA peripheral requests to do it like before but just writes a sample to the FIFO. Would really like to reformulate interrupt scheme on Coldfire to allow DMA interrupts to be blocked specifically but not normally.

81484e4b75 H1x0: Enable optical output to be switched on or off during playback and recording. Fixes FS#6414 - H120 opto out toggle freezes codec. Really DMA just needed a kickstart after setting the optical TXSRC if the peripheral requests were currently enabled (the method of detection).
