A hidden enc/dec mismatch bug was accidentally triggered by

Adaptively adjust mode test kick-off thresholds in RTC coding

This commit temporarily turns off the broken unit tests to avoid
blocking other CLs while fixing.

In many tests in VP8, the denoiser is disabled. By adding this
conditional comilation macro, the unit test will not be included
when denoiser is not enabled.

Check basic datarate targeting for a single bitrate
when the denoiser is on.

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.

One of the tests for real-time mode is failing at speed 6.
Introduced recently, will enable again when fixed.

-Properly set the average frame size for each layer.

-Allow each layer to update its average/last Q stats after encoding.

-Initialize for some layer context variables.

This patch adds a buffer-based rate control for temporal layers,
under CBR mode.

Added vpx_temporal_scalable_patters.c encoder for testing temporal
layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns).

Updated datarate unittest with tests for temporal layer rate-targeting.

   -Don't reduce maxQ for gold/alt in CBR mode.

   -Fix to min/maxQ for first/initial key frame.

   -Add more speeds to datarate test and reduce the starting bitrate for test.

This commit starts to convert the tests to a system where the codec
to be used is provided by a factory object. Currently no tests are
instantiated for VP9 since they all fail for various reasons, but it
was verified that they're called and the correct codec is
instantiated.

Exlcude key frame from buffer underrun check, and increase
lowest bitrate in BasicBufferModel.
Both changes are needed because of a known issue (#495).
