263e4d5cbf Minor optimization for musepack codec through moving functions to IRAM on PP processors. Speed ups codec by 0.25 MHzon PP5022.

b3d9578c27 Major change to musepack decoder: Import v1.3.0 (r458 from svn.musepack.net) to rockbox. Several adaptions in the musepack decoder were made to get the library work and perform fast under rockbox on several targets. With this change mpc sv8 is supported, including seek, replay gain and metadata support. The decoding speed is a 1-4% lower than the last implementation. Reason for this is main restructuring in the bitstream demuxer.

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.

5670ca18bb Fixes backward seeking on resumed files and backward seeking to positions to which formerly was seeked forward to (sounds complicated and it is).

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.

14698f5a20 Musepack performance optimization for PP5022/PP5024/MCF5250 targets. Use IRAM for internal sample buffers and lookup tables. Speeds up decoding by ~7% on PP5022/PP5024 (Sansa: c200, e200 + iPod mini2G, nano, video) and by ~27% on MCF5250 (iaudio m5, x5).

c78b019944 I figured out what was *really* causing the MPC track-change noise, so I 
backed out Thom's change and made the appropriate change. Note that this
should not fix the track change *pop* because there still seems to be a
problem decoding the first and last several hundred samples of MPC files.
