5177413d20 alac: conditionally set sign_modifier to 1
It is already unconditionally set to 0 prior to this, so we can modify it
only when needed.

7e6593e977 alac: eliminate 2 unneeded local variables in bastardized_rice_decompress()
x_modified is just unnecessary, and final_val can be removed by simplifying
the unsigned-to-signed conversion.

28f9ab7029 vp3: move idct and loop filter pointers to new vp3dsp context
This moves all VP3-specific function pointers from dsputil to a
new vp3dsp context.  There is no reason to ever use the VP3 IDCT
where an MPEG2 IDCT is expected or vice versa.

4cfb0d871d tscc2: do not add/subtract 128 bias during DCT
It turns out that the reference decoder subtracts 128 from DC during block
decode but adds it back during reordering block with zigzag pattern.
Transforming block with incorrect DC caused heavy visual artifacts for
many quantisers.
