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.

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.

Enforce that codecs wait for their metadata in a proper-ish and consistent manner. Sort of a halfway patch; best would be to give them an internal copy of the current track information which lasts unaltered by playback until a track switch or unload.

2010-03-22T10:02:05+00:00

Not only WAV but also Sun audio, SMAF, vox and WAV64 can resume.

corrects the smaf parser the following.

2010-03-13T05:53:54+00:00

- It is normally retrieved even if the position of wave data is not in given position from the head.
- The problem that artist/title/composer cannot be given normally when the character code != iso8859-1, utf-8.
- The problem that the position of chunk does not given correctly some mmf files.
- artist/title/composer stored in not id3v1buf but id3v2buf.
