d56999890f Make PCM->driver interface about as simple as it will get. Registered callback, zero data, alignment and stops are handled entirely inside pcm.c; driver merely calls fixed pcm.c callback. Remove pcm_record_more and do it just like playback; the original reason behind it isn't very practical in general. Everything checks out on supported targets. There wer some compat changes I can't check out on many unsupoorted but if there's a problem it will be a minor oops. Plugins become incompatible due to recording tweak-- full update. Sorted API.

20e9d56ba5 S#10387 - Rework pluginlib actions 
It changes pluginlib actions to contain only a single and simple context (and
other one for remote directional buttons),
consisting of 7(9) buttons: up/down/left/right, select OR short select and long
select, exit and cancel (plus 2 for scrollwheel targets).
This ensures contexts don't clash with other contexts and simplifies them, at
the expense of reduced versatility. However, the versatility made it largely unusable
due to the great number of targets.
This should allow for using pluginlib actions safely for the most simple plugins (e.g. almost all demos).

7250405c70 pitch_detector: Use continuous recording, even if the algorithm is too slow for that and record a whole buffer even if the min frequency is higher. Use the minimum samplerate that allows C-4186 to be detected (usually 11.025kHz, which can reduce computational load to 1/16 compared to 44.1kHz). Get rid of 64-bit multiplies when calculating input RMS value. Stop audio playback when entering plugin. Better backlight and CPU frequency handling. audio_sample_type->int16_t. simpler buffer size rounding.

c61e89c0ed Make creat() posix compliant API-wise. Shouldn't affect the core as it's wrapped via a static inline.
