9d98583a18 libmusepack: tiny optimization of the ARMv4 mpc_decoder_windowing_D implementations, using register indexed addressing to store data, saving one instruction in the loop and deleting one instruction adter the loop which isn't needed.

dbdc0a8a8c libmusepack: ARMv6 assembler for mpc_decoder_windowing_D, speeds up decoding of 128kbps sample file 2MHz, or 8%, on gigabeat S. The output difference to the c implementation and the other ARM implementation is +/-1 in less than 0.1% of the output samples.

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

db42781ca8 Fix FS#11261 (slow seek forward in mpc files). Since the introduction of the sv8 library mpc did not use efficient buffering when seeking forward. With this change the implementation will not flush the buffer on each frame but will keep the already buffered data as long as possible.

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.
