Miscellaneous bug-fixes for high bitdepth functionality.
With this patch, high bit-depth profiles become mostly functional,
except for an intermittent assert failure issue that is being
tracked.

This commit removes unused header file vp9_onyxc_int.h and repeatedly
included file vpx_ports/mem.h from vp9_block.h

Block transform skipping was implemented based on DCT's energy
conservation property. Modified the thresholds using zero bin
parameters. AC and DC coefficients were checked separately to
allow better identifying of skippable blocks.
Borg test at speed 3 showed:
stdhd set: psnr gain: 0.153%, ssim gain: 0.051%;
derf set: psnr gain: 0.023%, ssim gain: 0.036%
For most test clips, the encoding speedup is 1% - 2%.
parkrun(720p): 7.5% speedup, park_joy(1080p): 3.5% speedup.

For regular inter frames, if the distance from GOLDEN_FRAME is larger
than 2 and if the predicted motion vector of LAST_FRAME gives lower
sse than that of GOLDEN_FRAME, skip the GOLDE_FRAME mode checking in
the rate-distortion optimization. It provides about 5% speed-up at
expense of -0.137% and -0.230% performance down for speed 3. Local

When calculating delta in VP8 denoiser, since the block size is fixed to 16x16,
the divisor is 256, which is the number of the pixel.
But in VP9, the block size varies, the divisor should correspond to the block
size.

One is a more aggressive version of the pruned subpel tree
search where only a single halfpel candidate is searched.
The search candidate is based on a surface fit result.
The other is a method to obtain the subpel position at one
shot based on the same surface fit.
The methods have not been deployed in any speed setting yet.

This commit enables the encoder to skip checking ALTREF inter modes
in ARF coding, if the predicted motion vectors suggest that the
GOLDEN_FRAME provides higher prediction accuracy than ALTREF_FRAME.
It improves the speed 3 encoding speed by about 5%, at the expense
of compression performance loss -0.041% and -0.225% for derf and
stdhd, respectively.

This patch re-enabled the feature in Pengchong's patch
(commit 12861260732a4fd5f6b667ce9d5105dc9b606eda). Originally, it
was turned on while use_lastframe_partitioning > 0(not used anymore).
Now it was added as a feature, and turned on while speed >= 2.
As described in the original patch, this feature helps speed up the
slideshows in YouTube.
Change-Id: I1b0f18d65da1ee1c8d1e117dabba910c5207c471
Simplified the code and removed some code that was not used anymore.
This patch didn't change encoding result.

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%

Adds code to return an integer cost list for NSTEP search. Then
uses it for pruned subpel search in speed 3.
derf: -0.06%
Speed on mobcal 720p increaes from 10.28 fps to 10.65 fps.
[Subject to further testing].

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.

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.
