7ad2cad173 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.

5e57edf263 Clean up speex a bit after the playback changes in r29785. Haven't found any idiosyncracies not present before then. Fix it always returning CODEC_ERROR even when exiting codec_run normally.

08bedf8305 Having a default weak codec_main symbol doesn't seem to be working out for compiling the sim under cygwin in at least some cases. Just implement it explicitly in all cases.

c537d5958e 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.

b3bfc09852 r29348 changes can cause certain codecs to jump to code on early track change that assumes initializations have been done. Make sure that track change cleanups are only called if the state is sane to do so. Stops my vorbis data abort issue. Correctness for speex is a guess based on the library calls' source. It appears only speex/vorbis should have been bothered by said revision.

85e40257dc 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.

879070f89e * Clean up speex.c a little. 
* Sync to Speex SVN 12735 which includes some of our warnings fixes.
* Move decoder output to IRAM. Not much perfomance gain though.

97f369a587 SWCODEC: Annoying neatness update. Use intptr_t for codec_configure_callback and dsp_configure and stop all the silly type casting of intergral types to pointers to set dsp configuration and watermarks. Shouldn't have any effect on already compiled codecs at all. Will fix any important patches in the tracker so they compile.

7bf62e8da6 * Sync Speex codec with Speex SVN revision 12449 (roughly Speex 1.2beta1). 
* Redo the changes required to make Speex compile in Rockbox. Should be a bit easier to keep in sync with Speex SVN now.
* Fix name of Speex library in codecs Makefile.
