This commit enables unit test for SSSE3 16x16 inverse 2D-DCT with
10 non-zero coefficients. It includes a new test condition to
cover the potential overflow issue due to extremely coarse quantization.

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.

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.

This commit enables SSSE3 implementation of the inverse 2D-DCT
with only first 10 coefficients non-zero. It reduces the runtime
of SSE2 version from 745 cycles to 538 cycles, i.e., 27% speed-up.

The previous change only tunes forward transform. It doesn't affect
the neon implementation of the inverse transform. Hence turn the
unit test on.

The intepolation filter functions can be better tested withe extreme
values, especially given the optimization functions are prone to
overflow signed 16 bit intermediate value when operation order is
wrong.

This commit adjusts the forward 16x16 DCT computation steps to
simplify the register level operations. It fixes the corresponding
sse2 version accordingly.

Use VPX_TEST_NAME instead of the script name sans path and extension
when reporting test results when the variable is not empty.
Also: Clean up some style nits while I'm at it.

disabled by default, enable with:
--enable-experimental --enable-spatial-svc
this disables vp9_spatial_svc_encoder and svc_test, further work is
needed to remove internal lib references

As a side-effect, the max_sad check is removed from the
C-implementation of VP8, for consistency with VP9, and to
ensure that the SAD tests common to VP8/VP9 pass.
That will make the VP8 C implementation of sad a little slower
but given that is rarely used in practice, the impact will be
minimal.

The test vector has segment enabled with different quantizer used for
different segments for bot the first frame(key) frame and the rest of
non-key frames.
