The SSSE3 implementation might find a potential overflow issue in
its second 1-D transform, if all input residual pixels are close to
255. This commit fixes the issue and re-enables the unit test on
the SSSE3 version.

This commit reworks the unit test for 8x8 forward/inverse
transformation. It adds extreme input value test to detect overflow
issues in the intermediate steps.
It temporarily disables unit test for the SSSE3 version, which
showed overflow failure in the new test conditions.

Right now there is just one place to check: xd->lossless and for the first
pass there is a function is_lossless_requested().

In Aq mode 2 for kf/arf/gf the segment q delta
is calculated and then applied by re-quantization without
going through the rd loop again. If the base Q != 0
but the segment Q == 0 (lossless) this can could give rise
to a situation where we have an illegal combination of
transform size and Q. (Q == 0 requires that all blocks
are coded 4x4 WHT).

As a side-effect, the sad unit tests for VP8 and VP9
had to be separated.
Fixes a bug in original patch:
(https://gerrit.chromium.org/gerrit/#/c/70163/8)
that was reverted due to a nightly test failure.

This commit applies quantization process with coarse quantization
step size to the forward transform coefficients and tests all the
inverse 16x16 DCT and ADST implementation versions with the
dequantized coefficients as input, to verify that the outcomes
match the prototype.

In frame parallel decoding mode, there will be still several frames inside
the decoder when application stop calling vpx_codec_decode to decode frames.
The application will need to keep calling vpx_codec_get_frame to get all the
remaining decoded frames in the decoder.

This commit added a call to set speed feature before initializing
motion search, fixed the problem where unintialized search method
is used before its value being set.

By enabling the OUTPUT_YUV_SRC compiler flag, the encoder will write the raw
input to bd.yuv.
The functionality was mostly implemented, but in its previous state did not
compile.

Making this consistent with intra mode masks: you need to specify
allowed inter/intra modes to use.

SEG_LEVEL_SKIP requires the block size to be at least 8x8. Attempting to
use it on smaller partitions causes the decoder to reject the bitstream.

An overflow issue could potentially happen in the second round 1-D
transform of the SSSE3 full inverse 16x16 2D-DCT. This commit fixes
this issue.
