b957f7214b Rearrange the MDCT library lookup tables so that codecs can access them. Access them in cook. Remove old cook trig tables.

Improves performance signficantly on PP5024 (~200% realtime for a 64k file) while saving a lot of memory and improving accuracy.

b5b9cb031d Modified the code for seeking to speed it up a bit. Instead of searching 
the file for the required timestamp, we seek directly to a calcualted 
position. If we go to a point beyond the desired seek_time, we seek back 
in blocks (normally one or two blocks to the back) to get the required 
block.

bd70193e98 Commit rest of fix in FS#9866. Don't parse Vorbis comments again in libtremor. It wastes memory and we already have the comments in memory. Looking at the spec and code, I think this fix is proper, but if it breaks any files this may need to be revisited.

67695617a1 The first part of Mohamed Tarek's Google Summer of Code work to implement RealAudio support in Rockbox. This is a self-contained Cook decoder using the original ffmpeg (still floating point) decoder and a new RM parser started by me in 2008 and continued by MT over the past few months. This is the equivalent of libcook.patch1 from FS#10182, but with further cleaning by both MT and me to minimise the differences to the original ffmpeg files. See README.rockbox for more details.

fe04e40be7 Further optimised (vs. libgcc) unsigned 32 bit division for ARMv4 (based on the ARMv5(+) version from libgcc), in IRAM on PP for better performance on PP5002, and put into the codeclib for possible reuse. APE -c1000 is now usable on both PP502x and PP5002 (~138% realtime, they're on par now). Gigabeat F/X should also see an APE speedup.

2f50cd58b9 Codec memory reorganization 
Based on a patch by Tomasz Malesinski
* Merge Codec buffer and Malloc buffer into one large buffer.
* The new merged buffer is now 1MB on targets with lots of memory.
* Renamed codec_get_memory to codec_get_buffer and made it behave more. 
like plugin_get_buffer.
* Bumped Codec api and min api versions.

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.

46f85c4c54 Combine the Vorbis, WMA and AAC IMDCT functions and put them into the codeclib. Combined IMDCT is now based on existing Tremor transform. Reduces CPU for 192k AAC by 21MHz on Coldfire, and 5MHz on PP5024. WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs.

1334738071 Use Tremor IMDCT for WMA. Gives a ~20% speedup on ARM and coldfire. All my test samples gave equivilent or better accuracy (>>16 bit), but there may still be problems. Code becomes somewhat less readable since the IMDCT has bits of Vorbis in it, but this is not a serious issue and the old ffmpeg transform remains in SVN if anyone wants it. Also, WMA now passes Vorbis as the fastest transform codec on ARM, although MPC remains the fastest lossy codec overall.

c0951d95b3 Resort operands in mul/smull/mla/smlal to use D[] as second multiplication operand. Additionally do not pre-scale D[] for the 64 Bit precision synthesizer. Through this the 64 Bit multiplication is speed up by 1.5MHz without loss of precision.

f52696ef8a Correct DSP_SET_SAMPLE_DEPTH to 29 for mpc (18.14 fixed point samples). Higher precision for fast 32x32=32 multiplication in dewindowing part of synthesis filter.

cc11e9466a Further changes in mpc buffered seek. Remove magical number and replace it with a better commented #define. Use shift and bit mask instead of division and modulo operations when using the seek buffer. Saves some binary size for the codec.

bc97952134 libmad: PP5002 does in fact profit more from -O2 than PP502x, so use it for all targets. The previous check was half-baked (excluded iPod 3rd Gen only, but 1st/2nd Gen are also PP5002).

54ac25fcb2 Compile libmad with -O2 for the Ipods instead of just newer PP targets. Gives a 2% speedup on Ipods, but no change elsewhere. I've left the 3G alone, but its probably worth checking.

d23f78b1c6 fix FS#9042 - MOD codec: SoundTracker variant MOD files will not play 
- remove dubious format check and assume no formattag -> Soundtracker
- change method for remembering "periods converted" as the old one would corrupt Soundtracker files

6a74a5dd3b Commit FS#9015. Rework of musepack buffered seek. Now a static seek buffer of 8192 entries is used. The seeking precision is adapted to the length of the file (e.g. 26ms for files <=3.5min and 0.4s for files ~60min).

1d28fe7d79 Musepack seek hotfix. Do not dynamically allocate seek buffer but use a buffer of constant size (~28.5min). Files larger than this will still not seek properly. Some additional rework has to be done for the seek buffer.
