Use small transform size in non-rd real-time mode
In non-rd real-time mode, choosing smaller transform size in
encoding gives better video quality and good speed gain than
choosing larger transform size. This patch set tx size search
method to ALLOW_8X8, which is better than using 4x4 or other
larger sizes.
Borg tests on rtc set at speed 6 showed significant gain on quality.
PSNR gain: 11.034% and SSIM gain: 15.466%.
The speed gain is 5% - 12% for <720p clips, and 2% - 7% for
720p clips.

Revert "Removing this_frame_stats member from TWO_PASS struct."
Use of stack frame variable "fps" beyond the lifetime of the function.
fps is sent as a paremeter to output_stats and stored in the
packet holding this encoded frame. This has scope beyond the
lifetime of the calling function.

Enable unit test for partial 16x16 inverse 2D-DCT
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.

Fix potential overflow issue in SSSE3 forward 8x8 2D-DCT
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.

Rework unit test for 8x8 transformation
This commit reworks the unit test for 8x8 forward/inverse

issues in the intermediate steps.
It temporarily disables unit test for the SSSE3 version, which
showed overflow failure in the new test conditions.

Fix AQ mode 2 bug where delta causes Q 0.
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).

Refactor the vp9_get_frame code for frame parallel.
In frame parallel decoding mode, there will be still several frames inside

The application will need to keep calling vpx_codec_get_frame to get all the
remaining decoded frames in the decoder.

vp8 denoiser: fix to zero_mv mode selection.
In the current logic, if the sse for zero motion is smaller
than the sse for new_mv (i.e., best_sse), we may still end up
using the non-zero mv for denoising (if the magnitude of new_mv is above threshold).
This can happen for very noisy content, and can lead to artifacts.
This change ensures that we always use zero_mv (over new_mv) for
denoisng if sse_zero_mv <= best_sse.
