Fully remove floating point code from libmusepack. Introduce two small const arrays for precalculated scalefactors, correct the integer type of scalefactors to unsigned, migrate some metadata calculations to fixed point. No impact to decoder output.

Set alignment for major data arrays in the mpc codec. This avoids performance regressions on S5L870x CPUs when changing code and allows further improvements.

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.

Solve possible glitch after seeking in mpc files. Documented the special treatment after seek.

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.

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).

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.

Commit FS#9000. Speed up Musepack decoder by 3% on PP5022/24 via using ICODE_ATTR for calc_new_V(). Additionally correct a type in decoder-struct.
