099df2fb71 Make the codecs use more IRAM on S5L870x, as we have plenty of it.

2054627caa Have the codec thread do callbacks instead of messing with the stack which is much simpler and safer. Remove threads array from plugin API since it now serves no purpose. Up minimum API version and sort.

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.

c6b3d38a15 New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles. 
Many #include lines adjusted to conform to the new standards.

4e36a2b991 Commit FS#9318 - MP3 synthesis filter on COP. Loads the MP3 synth filer on to the CoProcessor on all PortalPlayer devices, resulting in an ~90% speedup according to test_codec on the Sansa. Real world improvement is somewhat less, but still considerable. Allows MP3 decoding at 30MHz without boosting, or use of more DSP/EQ with less boosting/skipping, thus improving battery life. Minor changes to mpegplayer to retain compatibility with libmad changes. Should be no significant changes for other targets or codecs.

2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

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).

27cf677339 Add a complete priority inheritance implementation to the scheduler (all mutex ownership and queue_send calls are inheritable). Priorities are differential so that dispatch depends on the runnable range of priorities. Codec priority can therefore be raised in small steps (pcmbuf updated to enable). Simplify the kernel functions to ease implementation and use the same kernel.c for both sim and target (I'm tired of maintaining two ;_). 1) Not sure if a minor audio break at first buffering issue will exist on large-sector disks (the main mutex speed issue was genuinely resolved earlier). At this point it's best dealt with at the buffering level. It seems a larger filechunk could be used again. 2) Perhaps 64-bit sims will have some minor issues (finicky) but a backroll of the code of concern there is a 5-minute job. All kernel objects become incompatible so a full rebuild and update is needed.

f90cbcb652 mpegplayer: Use the core DSP to process audio. Removes the sample rate restriction on audio and any mpeg audio samplerate may be used. Use the global sound settings for audio output with the option to force any one of the processing stages off. All are forced off by default. I didn't personally care to fully duplicate the Sound Settings menu which would have been needed since using the core one would affect settings globally and exactly the same configuration probably isn't desired since the CPU load for video playback is much greater. Rebalance the threading to compensate with some expense to buffering speed.

a5fc3f4df4 Initial WVS for mpegplayer. Adjusts to the user's preferred font and uses FF/RW preferences set for playback. Picked a random color for the base WVS color but it could be configured. Some engine tweaks to accomodate it since certain nescessities are clearer now. Fix a clipped YUV output bug in the SIM.

a222f27c4a mpegplayer: Make playback engine fully seekable and frame-accurate and split into logical parts. Be sure to have all current features work. Actual UI for seeking will be added soon. Recommended GOP size is about 15-30 frames depending on target or seeking can be slow with really long GOPs (nature of MPEG video). More refined encoding recommendations for a particular player should be posted soon.
