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.

* changes:
x86/convolve.h: remove redundant check in FUN_CONV_2D
x86/convolve.h: replace while w/if for w < 16
x86/convolve.h: change filter[] || chains to |
restore the value for VP9 to 9999 to satisfy the current test
expectations; without this
VP9/DatarateTestVP9Large.ChangingDropFrameThresh/8 will overshoot.

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:

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

some configurations may fail if AltRefTest is undefined though
VP8_INSTANTIATE_TEST_CASE is defined away.

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.

* changes:
x86inc.asm: only set visibility for chromium builds
Only use .text sections for aout
Use .text instead of .rodata on macho
Copy PIC handling code from x86_abi_support
Set 'private_extern' visibility for macho targets
Expand PIC default to macho64 and respect CONFIG_PIC from libvpx
Use libvpx defines to set name mangling rules
Customize x86inc.asm for libvpx
Update x86inc.asm from x264
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.

this restores the previous version's behavior avoiding issues with
builds that may split sources on directory boundaries; protected
visibility may work in this case.
