This reverts commit 691dec6201.
The commit did not fix ticket #3215, it was fixed one commit earlier.
The revert may break other use-cases but they should be fixed differently,
the offending commit introduced too many problems.
Fixes ticket #3377.
Fixes ticket #3378.

Based on the aarch64 asm. CPU cycle counts on cortex-a9 compared to
gcc 4.8.2:
before: 475 decicycles in get_cabac_noinline, 67106035 runs, 2829 skips
after: 393 decicycles in get_cabac_noinline, 67106474 runs, 2390 skips
Overall speedup is above 2%. Code generated by clang 3.4 is slower on
the same hardware and the relative change is a little larger.
Based on the x86 branchless get_cabac asm. get_cabac_noinline() gets
approximately 20% faster (no cycle counts available) compared to clang
from Xcode 5.1 beta5. More than 6% faster overall. A part of the overall
speedup might be explained by additional inlining of get_cabac().
Instead of using the demux function of libzvbi to split the packet to slices
(vbi lines), lets do it ourselves.
- eliminates the 1 frame delay between page input and output
- handles non-ascending line numbers more gracefully
- enables us to return error codes on some invalid packets instead of silently
ignoring them

The vector dequantization has a test in a loop preventing effective SIMD
implementation. By moving it out of the loop, this loop can be DSPized.
Therefore, modify the current DSP implementation. In particular, the
DSP implementation no longer has to handle null loop sizes.

For x86 Arrandale:
C SSE SSE2 SSE4
win32: 260 162 119 104

The arm NEON optimizations follow in a later patch as external asm. The
now unused check for the y modifier in arm inline asm is removed from
configure.
Based on a patch from Christophe Gisquet.
Unrolling of the m == 0 case avoids a possible use of the uninitilized
value sum when s->predictor_history is not set. I failed to find a
sample for it. It also reduced the cycle count from 220 to 150 on

Altivec can only load naturally aligned vectors. To handle possibly
unaligned data a second vector is loaded from an offset of the original
location and the data is recovered through a vector permutation.
Overreads are minimal if the offset for second load points to the last
element of data. This is 7 for loading eight 8-bit pixels and overreads
are reduced from 16 bytes to 8 bytes if the pixels are 64-bit aligned.
For unaligned pixels the overread is reduced from 23 bytes to 15 bytes
in the worst case.

set again before returning the frame.
The buffer holding the coefficients must be padded with 0 so as to use DSP
functions that may overread. Currently, the SSE2/3 versions is an example,
as they process batches of 16 bytes.

rpza: move some variables to the blocks where they are used

It was done only in check_mvset(), while mv_scale() is called also by
dist_scale().

The directional intra predictors either don't care about order (dc, h,
dc_left, tm), or they prefer inverted order (vr, dr, hd). This allows
more efficient SIMD implementations.
The spec doesn't describe how it should be decoded so this is probably
the safest thing to do. Fixes valgrind errors on fuzzed11.ivf and fixes
valgrind errors on fuzzed10.ivf differently.
When request_channel_layout is 0,
all substreams should be decoded.
Thanks to Michael Niedermayer for spotting.
Also fix a mismatch between the parser and
decoder when request_channel_layout is a
subset of Stereo.
