831cfb8e44 Add ASM optimised subband filtering loop for ARM targets. Restructure 
other loops a little bit.

153f906d74 Start converting codecs to use internal sample format (28 bits + sign, 
or s3.28 fixed point).

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.

4d9be96a81 Changed output format of libmpcdec to non-interleaved stereo for a slight speed boost. Also stopped wasting 10kb of IRAM in the output sample buffer.

d2456b44f7 Centralised the ICODE_ATTR and IDATA_ATTR #defines. Renamed some musepack and rockboy headers to avoid clashes with rockbox headers.

fe8663c548 See my message on the mailinglist. This should kill all warnings left in the iriver builds. And the changes will be added to the next musepack minor release.

c82518ce06 Replaced critical loop with assembler. A bit closer to realtime now. This codec really needs all the 64 bit muls replaced with EMAC equivalents.
