Unify PCM interface just above the hardware driver level for all targets including the sims. Perform lockout of audio callback when changing states. Weird new playback or recording trouble? Check before and after this revision first though things seem quite sound.

Remove the PCMREC_PARANOID support since the issues have been identified and fixed however detecting an encoder writing too many samples to a chunk will remain and be enabled in a DEBUG build as an aid for adding encoders. Do some cleanup on the filename queue. Loosen up the control interface where synchronous thread blocking isn't required for pause/stop/resume.

Use bitmasks to define which inputs are available. Makes it easier to remove old assumptions of which are available. Inspired by e200 being unique in having FM Radio and Mic but no Line. Doesn't remove the assumption that Mic is available or that one of Mic and/or Line is available just to avoid excessive #ifdef'ing until needed.

Make recording complain about every little file I/O problem (error on close() failure and fsync() failure). Why? I guess we will find out the disk is full about 1/2 sector sooner on average when the file APIs actually detect this correctly. :/

Place all recording functionality on pcmrec thread to serialize all recording operations. Button mash problems should be ruled out of pcm_record.c. Add additional lightweight checks by default and display any warnings that occurred during recording in first line of recording screen when they occur by blinking back and forth from warning display to normal line (Warning: <hex bitmask>). Warnings are cleared when beginning a new recording so write the number down if you see it and file a report. Add heavier checks when PCMREC_PARANOID is defined in the player config header (encoders and pcm_record must be aware of the define since it changes the chunk header format). These checks are mainly concerned with things that may cause skipping but also add unwanted overhead for normal operation. Best used with logf enabled.

Small change to PCM recording API for low latency effects. Latency can be as low as 14 samples from input to output including the FIFOs (ColdFire) but 16 is more reasonable an expectation if only tranferring one sample per interrupt (\!). May convert PCM playback to use the same method as it can still be used in the old manner with some slight mods but has the potential to enable new features since it is more flexible.

PCM: A few tiny changes. 1) Recording a) Flush all pending files if filename queue is full or else perpetual flushing of 1 will occur at low bitrates and short split times. b) #ifdef out currently unused bits and save little less than 1/2K 2) Cleanup some declarations.

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.
