Use the superframe counter to set the key frame, and force
it to the key frame on base spatial layer only.
Also, update svc frame counters under frame dropping.
Update unittest: add specific tests with short key frame period.

For 1 pass cbr mode: allow for two-stage 1:2 scaling
(which will use the 1:2 optimized scaler) if the spatial
layer is 1/4x1/4 of souce.
Without this change, the base layer for 3 spatial layers would
be using the non-normative scaler which is un-optimized/C code.

Use sharp filter to generate motion compensated reference for
temporal filtering. It improves the average coding performance of
VP9 speed 0:
derf 0.34%
hevcmr 0.38%
stdhd 0.58%

This commit back ports the fix from
https://chromium-review.googlesource.com/#/c/326940
It corrects the block partition context fetching in rate-distortion
optimization. It improves the average coding performance of speed 0:
derf 0.098%
hevcmr 0.102%
stdhd 0.282%

The double pointer in xd->mi handles this for us.
Cuts encode_suberblock()'s self time in half at rt speed 8.

This reverts commit f51f0998e1.
This causes datarate tests to fail. Some are due to the new default
keyframe distance, another causes an assert even forcing 9999:
[ RUN ] VP9/DatarateOnePassCbrSvc.OnePassCbrSvc3SpatialLayers/0
test_libvpx:
vpx_dsp/x86/vpx_subpixel_8t_intrin_ssse3.c:853: scaledconvolve2d:
Assertion `y_step_q4 <= 32' failed.

Reset the scale factors before build_inter_predictors.
Add datarate tests for 3 spatial layers, which exposed this issue.

the same as vp8, with the same reasoning from:
2a0d7b1 Reduce the default kf_max_dist to 128.

+ restore vpxenc behavior of taking the library default rather than
forcing 5s
This change also exposes an issue with one-pass svc in cbr mode, keep
the old default in datarate_test.cc for now.

Use the existing scene/content change detection to better
update/adjust golden frame refresh.
Change only affects 1 pass real-time vbr mode, speed >=5.

Don't initialize first pass costs for a number of symbols where first
pass probabilities aren't initialized.
This brings a 1.22x first pass speedup.

move to encoder_encode() as vp9_get_compressed_data() allocates data and
would require some modification to make its error return meaningful.
