Control already exists for vp9, adding it to vp8.
Usage is only when error_resilient is off.
Added a datarate unittest for non-zero boost.

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%.

Don't advance the svc frame counters on dropped frame,
since this can break the referencing scheme and lead
to a crash/assert.
Updated svc-datarate unittest to add a lower bitrate test.
Change only affects 1 pass cbr svc, with frame dropper enabled.

Use the superframe counter to set the key frame, and force
it to the key frame on base spatial layer only.
Also, update svc frame counters under frame dropping.
Update unittest: add specific tests with short key frame period.

For 1 pass cbr mode: allow for two-stage 1:2 scaling
(which will use the 1:2 optimized scaler) if the spatial
layer is 1/4x1/4 of souce.
Without this change, the base layer for 3 spatial layers would
be using the non-normative scaler which is un-optimized/C code.

restore the value for VP9 to 9999 to satisfy the current test
expectations; without this
VP9/DatarateTestVP9Large.ChangingDropFrameThresh/8 will overshoot.

the same as vp8, with the same reasoning from:
2a0d7b1 Reduce the default kf_max_dist to 128.
see also:
https://trac.ffmpeg.org/ticket/4904
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=815673
+ restore vpxenc behavior of taking the library default rather than
forcing 5s
This change also exposes an issue with one-pass svc in cbr mode, keep
the old default in datarate_test.cc for now.

-Make Rate control work for SVC 1 pass CBR mode.
-Added temporal layering mode.
-Fixed bug in non-rd variance partition.
-Modified/updated the sample encoders (vp9_spatial_svc_encoder, vpx_temporal_svc_encoder).
-Added datarate unittest(s) for 1 pass CBR SVC.

this removes the CONFIG_* checks from public headers, but means
'--enable-experimental --enable-spatial-svc' builds will fail without a
local change to the ABI in vpx_encoder.h. this should be all right for
testing this experiment.

Crash occured on very first key frame, because denoiser
temporal function was beng entered.
Updated denoiser unittest to set cpu_used from first frame,
and verified fix fixes the crash.

Modified the thresholds of deciding whether or not to skip
the transforms in model_rd_for_sb_y(). Used zbin[] instead
of dequant[] to be more precise. Also, modified the checking
coditions.
Rtc set borg test results (at speed 6) showed:
average PSNR gain: 0.138%, overall PSNR gain: 0.158%,
and SSIM gain: 0.177%.
The data rate test was modified slightly as suggested by
Marco.

The denoiser sensitivity level should be set to 1 starting from
key frame. The internal function of denoiser should make the
temporal denoising operations cut off in key frame coding.

This commit makes the codec automatically turn on error resilient
mode when using real-time mode for temporal scalable coding. It
fixes an enc/dec mismatch issue and re-enables the corresponding
unit test.

Before encoding a frame, calculate and store each 16x16 block's
variance of source difference between last and current frame.
Find partitioning threshold T for the frame from its variance
histogram, and then use T to make partition decisions.
Comparing with fixed 16x16 partitioning, rtc set test showed an
overall psnr gain of 3.242%, and ssim gain of 3.751%. The best
psnr gain is 8.653%.
The overall encoding speed didn't change much. It got faster for
some clips(for example, 12% speedup for vidyo1), and a little
slower for others.
Also, a minor modification was made in datarate unit test.

This commit adjusted the speed steps in rt mode to make the steps
more evenly spaced on speed and quality, specifically:
1. Merged 3 and 4 into one single step 3 and removed confilicting
features.
2. Move 8, 7, 6, 5 to be 7, 6, 5, 4 repsectively.
