The current one, while correct, does not yield the best possible
results. The specificiations suggest another formula, which results
in quality gains in the decoded output from fate tests. This
justifies changing said formula.

It is only (mis-)used to set the dsp fucntions clear_block(s). But
these functions always work on 16bits-wide elements, which make
the parameter useless and actually harmful, as it causes all content
on more than 8-bits to not use accelerated functions.

Commits 43bc5cf9 and c5371f77 add code for skipping initial zeros in mp3
packets. This code forgot to report to the user that data was skipped at
all.

Since audio codecs allow partial packet decoding, the user application
has to rely on the return value. It will remove the data reported as
consumed by the decoder, and feed it to the decoder again. This resulted
in the mp3 frame after the zero region to be decoded over and over
again, until the zero region was finally skipped by the application.

Fix this by including the amount of skipped bytes to the number of
consumed bytes returned by the decode call.

Fixes trac ticket #4890.

CID 1256 is specified as using the same table for luma and chroma,
which is the same as CID 1235 luma table. This is consistent with
the format supposedly being RGB, although most sequences seem to
actually be YCbCr-encoded.

VideoToolbox also implements a software decoder for h264, and will fallback to
using it if the file cannot be decoded on the GPU. In these cases though,
we want the hwaccel to fail so that we can use the libavcodec software decoder
instead of the Apple one.
