e88d24a840 Submit parts of FS#12189 regarding codec API. Replaces access to global settings with a dedicated function to determine if the current track shall be looped. Used by several synthesizer codecs.

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.

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.

12375d1d3a Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them.

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.

21f0c9a282 Make basic cache functions into calls, and get rid of CACHE_FUNCTION_WRAPPERS and CACHE_FUNCTIONS_AS_CALL macros. Rename flush/invalidate_icache to cpucache_flush/invalidate. They're inlined only if an implementation isn't provided by defining HAVE_CPUCACHE_FLUSH/INVALIDATE.

8cfbd3604f Use cookies for thread identification instead of pointers directly which gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats. Everything gets incompatible so a full update is required.

effceea229 Remove the event object in the kernel since it's rather extraneous at the moment. This makes the codecs and the plugins incompatible, so update fully.

05099149f1 Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit).

ef1f7d3bf9 SPC Codec: Ensure no crash occurs on load failure which could cause emulation to be run without a program loaded on dual core (DSP wasn't initialized yet). The load failures come from core buffering not having the atomic audio file fully loaded before the codec requests the buffer (it gets as many bytes as can be provided) which IMHO isn't very atomic :). Changes in thread execution order after dumping spinlocks for general use simply revealed the buffering race condition. No fix for that will be hacked into the codec itself but should be fixed in the core. Add my copyright to files I had a significant part in developing per request of Adam Gashlin.

d4e904bf35 SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update.
