Do a bandaid fix for the moment to address FS#12250 : Playback freezes when using speed or pitch change. Task should remain open for now since this is just a brute force buffer increase rather than (re)endowing the DSP with the expected behavior.

Commit work started in FS#12153 to put timing/position information in PCM
...
buffer chunks.
* Samples and position indication is closely associated with audio data
instead of compensating by a latency constant. Alleviates problems with
using the elapsed as a track indicator where it could be off by several
steps.
* Timing is accurate throughout track even if resampling for pitch shift,
whereas before it updated during transition latency at the normal 1:1 rate.
* Simpler PCM buffer with a constant chunk size, no linked lists.
In converting crossfade, a minor change was made to not change the WPS until
the fade-in of the incoming track, whereas before it would change upon the
start of the fade-out of the outgoing track possibly having the WPS change
with far too much lead time.
Codec changes are to set elapsed times *before* writing next PCM frame because
time and position data last set are saved in the next committed PCM chunk.

Fix FS#12238 - WPS delay on pause introduced by r30097 which was the excuse I wanted anyway to do a better PCM fade on stop/pause implementation. New fade is asynchronous tick-based. Restores skin update points in the WPS that were removed when fading mechanism was changed.

The voice PCM buffer has nothing to do with the playback PCM buffer any longer. Allocate it independently from the playback engine's PCM buffer and only when voice is required. Additionally, allocate actual space for the crossfade buffer only when using crossfade. Will save 18.3KB when neither is needed (10.3KB for voice and 8.0KB for crossfade).

Commit FS#12150 - Fully-functional audio mixer - and finally whip old limitations about playback of voice and other sounds when paused. Channels are independent in state and amplitude. Fade on stop/pause is handled by the channel's volume control rather than global volume which means it now works from anywhere. Opens up the possibility of plugin sounds during music playback by merely adding an additional channel enum. If any PCM drivers were not properly modified, see one of the last comments in the task for a description of the simple change that is expected. Some params are tunable in firmware/export/pcm-mixer.h as well.

Commit FS#12069 - Playback rework - first stages. Gives as thorough as possible a treatment of codec management, track change and metadata logic as possible while maintaining fairly narrow focus and not rewriting everything all at once. Please see the rockbox-dev mail archive on 2011-04-25 (Playback engine rework) for a more thorough manifest of what was addressed. Plugins and codecs become incompatible.

Give playback engine better control over the codec. Codec simply follows commands and doesn't concern itself with audio state. Get track change notification in on the actual last buffer insert of the track because now audio simply waits for a track change notify from PCM on the last track and it must be sent reliably. This is still at an intermediate stage but works. Codecs and plugins become incompatible.

Redo raising the priority of the codec (and voice) thread to fix audio dropouts under heavy UI load, such as during kinetic scrolling or pictureflow.
...
Now it'll raise the priority gradually when under 70% and gradually decrease again in the same way.
Previously it raised gradually when under 17% (way too late) and went straight back to default priority above 17% again.

Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with #if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently).
...
The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR).
The new define is to (de-)select code to compile on hosted platforms generally.
Should be no functional change to targets or the simulator.
