This is actually internal utvideo format.
Allows to make use of SIMD for median prediction for rgb(a) formats,
thus speeding up decoding.
Simplifies code, eases further developement and maintenance.
Update FATE because of pixel format switch.

its failure is considered.

Takes a raw input stream containing frames with correct timestamps but
possibly out of order and inserts additional show-existing-frame
packets to correct the ordering.
(cherry picked from commit 34e051d168)
(cherry picked from commit b43b95f478)
Also converted from bitstream to get_bits.
set_ue_golomb just support 2^16 - 2 at most, becase this function call
put_bits, and put_bits just support write up to 31 bits, when write 32
bit in put_bits, it's will overwrite the bit buffer, and the default
assert level is 0, the av_assert2(n <= 31 && value < (1U << n)) in
put_bits can not be trigger runtime.

This was added in e3e3c82555, probably
as a workaround for the fact that the quant table was not permutated
and the IDCT coefficients are, meaning that you'd only get correct
reconstruction if the IDCT permutation was an identity matrix, which
happens to be the case when you use the simple IDCT. The quant table
permutation bug was fixed in 42dd1434bf,
meaning this workaround is no longer necessary.
In practical terms, before 42dd1434bf,
the PSNR between decodes of the fate-mdec using simple (C) or simplemmx
IDCTs was 35. After 42dd1434bf, it's 90.
Properly use the b.eq form instead of the nonstandard form (which
both gas and newer clang accept though), and expand the register
lists that used a range (which the Xcode 6.2 clang, based on clang
3.5 svn, didn't support).

Use avci->last_pkt_props to get the side data. Using |pkt| doesn't work
when FF_API_MERGE_SD is set, as the compressed side data is expanded into

Use named arguments for the functions so we can remove a define. The
stride/linesize argument is now ptrdiff_t type so we no longer need to
sign extend the register.
