Increase the qp-delta, mainly for low resolutions,
excluding case of very low bitrates.

avgPSNR/SSSIM gain of ~3-5% on rtc_derf set.
Small change on rtc set.

Affecting only speed 8.
Speed tests on Nexus 6 show 4% faster for QVGA and 2.4% faster for VGA.
Little/negligible quality regression observed on both rtc and rtc_derf sets.

Affect only speed 8. Small/Negligible regression on rtc set.

This currently runs 1000 * 1000 = one *million* times which is quite
unnecessary. It's one of the slowest items in Jenkins and takes over an
hour for each of the larger transforms.

Due to recent change to speed >=7 from commit:219cdab6.

Change-Id: I366e7750ec91119881050ff6c05849504c7959e8

Only for speed >= 7, and affects skipping of intra modes.
Threshold is set low for now, needs to be tuned.
Small/no difference in metrics on rtc clips.

Added the multi-threaded first pass encoder unit test in VP9. The test is
to check if the new multi-threaded first pass encoder(namely, new-mt = 1)
still generates matching stats. In the unit test, the new-mt mode will be
turned on once the multi-threaded first pass implementation is checked in.

For short_circuit set to level 1, skip newmv for 64x64 blocks if the
low temporal variance flag is set. Also modify threshold for 64x64 split
in variance partitioning.

Overall speed-up on noisy clips of 2-4%.
Only affect speed >= 7.

Avoid quality loss when copying partition of superblock with large motions.
Maximum consecutively copied frames can be set (currently 5).

Also set the flag to 1 when exit early choosing 64x64 block
such that skipping new mv for golden works in these scenerios.

Change the size of prev_segment_id to the number of superblocks
to save memory.

Borg test shows quality regression of 0.012% on average PSNR
and 0.035% on SSIM.

Adds an optional output framestats.csv file that prints comparions
per-frame instead of averaged over the entire clip. It prints
per-channel and combined metrics for SSIM and PSNR.

copy_partition is set.

Avoid many visual artifacts. Compression quality is improved by more
than 1%. Encode speed is about 4% for QVGA and 6% for VGA faster on
android.
