the gtest implementation used only returns values between 0 and 2^31-1

+ temporarily disable some tests in fdct8x8_test which misbehave with the
  new range

For a few refresh periods after key frame, use large qp-delta
to increase quality ramp-up.

For key frame at speed 6: enable the non-rd mode selection in speed setting
and use the (non-rd) variance_based partition.

Adjust some logic/thresholds in variance partition selection for key frame only (no change to delta frames),
mainly to bias to selecting smaller prediction blocks, and also set max tx size of 16x16.

Loss in key frame quality (~0.6-0.7dB) compared to rd coding,
but speeds up key frame encoding by at least 6x.
Average PNSR/SSIM metrics over RTC clips go down by ~1-2% for speed 6.

This commit reworks the ONE_LOOP_REDUCED coefficient probability
model update process. It allows model update for every coefficient
across the spectrum at a coarser resolution, instead of performing
precise update only for certain subset of probability models.

The overall runtime remains nearly same (<1% change) for speed -6.
The compression performance is improved by 7.5% in PSNR for speed
-5 and 4.57% for speed -6, respectively.

Synchronize all threads immediately as a subsequent decode call may
cause a resize invalidating some allocations.

Change 72056 unfolded some macro definitions,
but lost some alternative behaviour required for
high bitdepth encodes.
This causes the encoder to crash, see issue 884.

Also removes some spurious changes in common/vp9_blockd.h which
was introduced by a rebase issue between nextgen and master branches.

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.

Incorporate segment delta-q into estimated bits.
This generally improves the rate control under cyclic refresh (aq=3) mode.

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.

Probably not even the dominant platform the library is being built for.
Add --cpu= option description to help. The option already exists.

Don't allow passing just --cpu as a no-op.

Each tile's tok starting address is calculated before the encoding
process. These addresses are stored so that the same calculation
won't be done again in packing bit stream.
