f163b405c0 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.

b086458e4e FS#12231 
Centralize the selection of codec compilation flags to codec.make
to avoid having to duplicate the per cpu selection logic and the
build rule in the individual codec lib make files and make tweaking
easier.

The two special cases, libmad and libspeex were left alone.

I plan to introduce a var for arm generation so that appropriate flags
can be selected per generation as benchmarking results have shown that
different arm arches might have different optimal flags.

32838e96d0 Finally fix FS#11476 (data abort when playing some sv8 mpc files on lowmem targets like Clip+/Fuzev1/Fuzev2). This fix disables loading of seek tables from the sv8 bitstream. Those table are located at the end of sv8-files. When playing sv8 files this resulted in seek to filebegin, then fileend, then back to filebegin. Such seeking behaviour results in heavy rebuffering when playing files on targets with low RAM.

45c7498f59 FS#11335 by me: make ARM assembly functions thumb-friendly 
We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+

Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

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.
