This commit changes the call in vp9 encoder from vp9_deblock() to
vp9_post_proc_frame() to ensure the data structures used in the call
are properly allocated. This fixes an encoder crash when configured
with --enable-internal-stats.

Allow usage of lookahead for VBR in real-time mode, for 1 pass vbr.
Current usage is for fast checking of future scene cuts/changes,
and adjusting rate control (gf interval and active_worst/target size).
Added unittests (datarate) for 1 pass vbr mode, with non-zero lag.
Added an experimental option to limit QP based on lookahead.
Overall positive gain in metrics on ytlive set:
avgPNSR/SSIM up on average ~1-3%; several clips up by 5, 7%.

This change eliminates redundant computation in the two stage
downscaling, which saves ~1% encoding time in 3-layer svc encoding.

Modify the gfu_boost and af_ratio setting based on the
average frame motion level.
Change only affects 1 pass vbr.
Metrics overall positive on ytlive set.
On average up by ~1%, several clips up by 2-4%.

Use the precise context to estimate the zero token cost in trellis
optimization process. This improves the speed 0 coding performance
by 0.15% for lowres and 0.1% for midres. It improves the speed 1
coding performance by 0.2% for midres and hdres.

This commit allows the inter prediction residual to use uniform
quantization followed by trellis coefficient optimization in
speed 0. It improves the coding performance by
lowres 0.79%
midres 1.07%
hdres 1.44%

Move the operations that update the context buffers outside this
function. The coeff_cost() takes all input as const value and returns
the coefficient cost.
This makes preparation for the next coefficient optimization CLs.

Replace the existing mv bias with a bias only for
NEWMV, and based on the motion vector difference of
its top/left neighbors.
For cbr non-screen-content mode.

Use pixel domain distortion metric in speed 0. This improves the
compression performance by 0.3% for both low and high resolution
test sets.

Safer to have the decoder operate normally and have
better-hw-compatibility only implement encoding changes.
Fixes some test failures.

For real time CBR mode, use model_rd_for_sb_y for 32x32 if the sb is
a skin sb to avoid visual regression on the slowly moving face.

The transform block row and column positions are always available
outside the callees. There is no need to re-compute these values
again. This approach has been used by the decoder. This commit
removes txfrm_block_to_raster_xy() function.

these are debug-only modules that can be added in manually when needed.

Moved the API patch from NextGenv2. An example was included.
To try it, for example, run the following command:
