For testing implemented a fixed pattern and delta, 1 pass,
fixed Q, low delay mode.

This has not in any way been tuned or optimized.

(copied from VP9)

The one pass VBR mode selects a Q range based on a
moving average of recent Q values. This calculation
should have been excluding arf overlay frames as these
are usually coded at the highest allowed value. Their
inclusion skews the average and can cause it to drift
upwards even when the clip as a whole is undershooting.

As such it can undermine correct adaptation of the allowed
Q range especially for easy content.

The culprit is on the decode side xd->lossless[i] setup was in wrong
location where segment features are not yet decoded.

Also on the encoder side, transform mode was not set consistently
between when tx_mode is selected and how tx_mode is enforced in
tx size selection.

Keep track of frame indexes for the references, and
constrain inter mode search for reference with same
temporal alignment.

Improves speed by about ~15%, no noticeable loss in
compression performance.

Lower the threshold for splitting 32x32->16x16 based on average variance,
and add lower bound condition for this split to occur. This prevents
unneccassry splitting for areas with very low variance.

For non-rd variannce partition, speed >= 5:
Adjustments to reduce dragging artifcat of background area near
slow moving boundary.

-Decrease base threshold under low source noise conditions.
-Add condition to split 64x64/32x32 based on average variances
of lower level blocks.

PSNR/SSIM metrics go down ~0.7/0.9% on average on RTC set.
Visually helps to reduce dragging artifact on some rtc clips.

GET_GOT modifies the stack pointer so the offset for left's address will
be wrong if loaded afterword.
