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 several 'variable set but not used' warnings reported from GCC 4.6.0.

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.

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.

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.

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.

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.
