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.

--rt --cpu-used=-5 uses the progressive rtc mode
--rt --cpu-used=-6 uses the new super fast rtc mode

* Avoid unnecessary type erasure
* Prune unused/duplicate fields from struct rdcost_block_args
* Make struct rdcost_block_args a local

In this new mode, the size range is strictly determined by the min
and max partition size in neighborhood blocks.
Niklas720 encoding time at cpu-used -5 goes from 56250ms to 50676ms,
a 10% reduction.

Applies an upper limit on burst bitrate for any
frame. This is to insure that typical encodes for YT
do not produce frames that are so large that they
risk stalling HW implementations. Such frames
could also cause playback problems in SW.
For now the limit is set at 250 bits per MB for 1080P
and larger (with the 1080P limit used for smaller frames).
Setting maxQ, constant quality mode or targeting a
very high bandwidth will have precedence over this limit.

Introducing calc_psnr() which calculates psnr between two yv12 buffers.
Previously we incorrectly used width/height instead of
crop_width/crop_height to calculate number of samples -- fixed.

Added comments to explain what the various speed features do, and removed
1 that was clearly unused.

The feature undergoes prior assumption that the recursive partition
size search from 4x4 to 64x64, hence utilizing information from small
blocks to determine early termination in large block rate-distortion
optimization search. The current codebase is now going from top down.
The previous function might go with not properly initialized values,
hence removed.
Tested on pedestrian_area_1080p at 4000 kbps running under speed 2.
No visible difference in runtime observed.

In two pass encodes bits are allocated to each frame
according to a modified error score for the frame as a
fraction of the modified error score for the clip or section.
Previously a minimum rate per frame was reserved and
subtracted from the bits allocatable by the two pass code.
The vbr max section rate was enforced by clipping the
actual number of bits allocated.
In this patch the min and max vbr rates are enforced
instead by clipping the modified error scores for each frame
rather than the number of bits allocated.
Small gains for all test sets (psnr and SSIM) ranging from
~ +0.05 for YT psnr up to ~ +0.25 for Std-hd SSIM.
