4a101310e8 Adapt mode based rd_threshold for similar block size
The rd_thresholds are adaptively changed based on best mode tested.
It was only changed for the same block size, this commit makes the
adaptation for similar block sizes too. The commit also made minor
adjustment and code cleanups.

The impact on encoding time for _ped:
118089 ms -> 111927 ms

The impact on compression:
derf:  -0.339%
stdhd: -0.303%

eee904c9b9 Adaptive mode search scheduling
This commit enables an adaptive mode search order scheduling scheme
in the rate-distortion optimization. It changes the compression
performance by -0.433% and -0.420% for derf and stdhd respectively.
It provides speed improvement for speed 3:

c70cea97ac Remove mi_grid_* structures.
mi_grid_* are arrays of pointer to pointer. They save the pointers that point
to the MIs in cm->mi. But they are unnecessary and complicated. The original
goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer
inside MODE_INFO_t, same goal could be achieved.

This commit totally removes the mi_grid_* structures. But there are still
many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit
will do on-demand MODE_INFO_t allocation in order to save these memories.

209ee12110 [spatial svc] Remove vpx_svc_parameters_t and the loop that sets it for each layer
vpx_svc_parameters_t contains id, resolution and min/max qp for each spatial layer.

In this change we will use extra config to send min/max qp and scaling factors, then calculate layer resolution inside encoder.

c389b37bb4 Substantial reworking of code for arf and kf groups.
Substantial restructuring of the way we estimate
the rate of decay in prediction quality and determine
the arf interval and amount of boost used.

Also other changes to support moving to a lower first pass
Q which exposes some new features and allows us to better
distinguish genuinely static blocks from low motion or noisy
blocks.

Net gains now visible on all the test sets with std-hd PSNR up
1.87%. There are still some bad outlier cases but most of these
are low motion or slide show type content where the metrics
are already high at any given rate. The best + case is up by
more than 10%.

888a848453 Remove redundant reference frame threshold settings
When a reference frame type is not in the frame buffer, the mode
search threshold will be set to INT_MAX, so as to effectively
turn off the mode entries in the rate-distortion optimization loop
that involves this reference frame type. This operation is now
integrated in the ref_frame_skip_mask scheme. This commit hence
removes the redundant mode search threshold setting.

Improves function to return sad of integer pels by reusing integer

Turns on BIGDIA search for speed 4. Also, turns on the

Speed seems to improve by at least 5% but subject to verification.

stages of the transform computation respectively rather than fixed
types int16_t/int. When vp9_highbitdepth configure flag is off,
these map tp int16_t/int32_t, but when the flag is on, they map
to int32_t/int64_t to make space for needed extra precision.

47380c3350 Fix the bug which made VP8 denoiser not bit-exact between C code and SSE code.
This issue is found when the denoising mode is set to kDenoiserOnYUVAggressive.
Updated the C code to make it the same with SSE version.

I also changed several lines in VP9 denoiser for the code style.

68d79146ea Fix a bug in vp9_rd_pick_inter_mode_sb
This commit fixes a bug related to skipping intra mode checking, by
using a separate variable to store the best prediction error from
inter mode. It avoids unintentionally overwriting intra mode
rate-distortion cost, and hence affecting other speed features.

9a9e2aef09 Remove redundant ref frame pointer assignment
Assigning selected reference frame pointer is done in the
encode_superblock function. No need to do this at the end of
rate-distortion optimization search.

33593d1f03 Remove dependency of intra mode search skip check on mode order
This commit refactors the vp9_rd_pick_inter_mode_sb function to
remove the intra mode early termination dependency on the mode
search order.

d96228a07c Replace best_mode_index table retrieve with fetching best_mbmode
This commit allows the encoder to find current best prediction mode
state using best_mbmode, instead of fetching from the static mode
search table via best_mode_index.

f10d7eeda2 Remove the use of use_lastframe_partitioning at speed 4
The use of use_lastframe_partitioning is totally removed in good-
quality encoding. Its usage in real-time encoding needs to be
evaluated to see if it can be removed too.

The Borg tests at speed 4 showed:
stdhd set: 0.220% psnr gain, 0.166% ssim gain;
derf set:  0.329% psnr gain, 0.476% ssim gain.

Speed test on selected clips showed 1.54% speedup.(Worst case:
pedestrian_area_1080p25.y4m, speed loss: 1.5%)

1092140379 No longer use use_lastframe_partitioning speed feature
The speedup in rd_pick_partition() function makes it possible
to drop use_lastframe_partitioning feature. By doing that, we
achieve good PSNR gain with small speed loss. Also, this makes
encoding loop less complicated. The code cleanup patch will
follow.

Borg tests showed:
1. At speed 2,
   stdhd set: 0.201% PSNR gain, 0.133% SSIM gain;
   derf set:  0.262% PSNR gain, 0.276% SSIM gain.
2. At speed 3,
   stdhd set: 0.139% PSNR gain, 0.109% SSIM gain;
   derf set:  0.447% PSNR gain, 0.442% SSIM gain.

The average speed loss over selected test clips is within 1%
with the worst case of 4%.
