Added a new expt rect-tx to be used in conjunction with ext-tx.
[rect-tx is a temporary config flag and will eventually be
merged into ext-tx once it works correctly with all other
experiments].
Added 4x8 and 8x4 tranforms for use initially with rectangular
sub8x8 y blocks as part of this experiment.
There is about a -0.2% BDRATE improvement on lowres, others pending.
When var-tx is on rectangular transforms are currently not used.
That will be enabled in a subsequent patch.

- HBD encoder speed improvement (SSE4.1):
Enable CONFIG_VP9_HIGHBITDEPTH, on Xeon E5-2680,
50 frames, park_joy_1080p, 12-bit,
Encoding time reduces from 4846481 to 4177471 (ms)
- Add unit test to verify bit-exact and EOB calculation

Currently nothing is implemented to compute GM parameters, this
just adds the capability to send them in the bitstream if they
were computed. Still need to implement the reconstruction
based on the parameters in reconinter.

ARF with zero strength temporal filter can be reused by setting the
show_existing_frame = 1, and in this case, there is no need to
refresh the reference frame buffer. However, we used the flag
"refresh_golden_frame" as the identifier for the starting point of a gf
group.
A new flags "is_arf_filter_off" is used to record if the filter with
strengrh zero is used.

Keep track of the best and second best full pixel motion vector
candidates, and do subpel search around both of them.
Compression improvement:
lowres 0.22% midres 0.23% hdres 0.18%
No noticeable encoding speed changes observed on lowres test clips.

This commit bring all up-to-date changes from master that are
applicable to nextgenv2. Due to the remove VP10 code in master,
we had to cherry pick the following commits to get those changes:
Add default flags for arm64/armv8 builds
Allows building simple targets with sane default flags.
For example, using the Android arm64 toolchain from the NDK:
https://developer.android.com/ndk/guides/standalone_toolchain.html
./build/tools/make-standalone-toolchain.sh --arch=arm64 \
--platform=android-24 --install-dir=/tmp/arm64
CROSS=/tmp/arm64/bin/aarch64-linux-android- \
~/libvpx/configure --target=arm64-linux-gcc --disable-multithread

configure: clean up var style and set_all usage
Use quotes whenever possible and {} always for variables.
Replace multiple set_all calls with *able_feature().
Conflicts:

vp9-svc: Remove some unneeded code/comment.
datarate_test,DatarateTestLarge: normalize bits type
quiets a msvc warning:
conversion from 'const int64_t' to 'size_t', possible loss of data
mips added p6600 cpu support
Removed -funroll-loops
psnr.c: use int64_t for sum of differences
Since the values can be negative.
*.asm: normalize label format
add a trailing ':', though it's optional with the tools we support, it's
more common to use it to mark a label. this also quiets the
orphan-labels warning with nasm/yasm.
BUG=b/29583530
Prevent negative variance
Due to rounding, hbd variance may become negative. This commit put in
check and clamp of negative values to 0.
configure: remove old visual studio support (<2010)
BUG=b/29583530
Conflicts:
configure
configure: restore vs_version variable
inadvertently lost in the final patchset of:
078dff7 configure: remove old visual studio support (<2010)
this prevents an empty CONFIG_VS_VERSION and avoids make failure
Require x86inc.asm
Force enable x86inc.asm when building for x86. Previously there were
compatibility issues so a flag was added to simplify disabling this
code.
The known issues have been resolved and x86inc.asm is the preferred
abstraction layer (over x86_abi_support.asm).
BUG=b:29583530
convolve_test: fix byte offsets in hbd build
CONVERT_TO_BYTEPTR(x) was corrected in:
003a9d2 Port metric computation changes from nextgenv2
to use the more common (x) within the expansion. offsets should occur
after converting the pointer to the desired type.
+ factorized some common expressions

Update vpx subpixel 1d filter ssse3 asm
Speed test shows the new vertical filters have degradation on Celeron
Chromebook. Added "X86_SUBPIX_VFILTER_PREFER_SLOW_CELERON" to control
the vertical filters activated code. Now just simply active the code
without degradation on Celeron. Later there should be 2 set of vertical
filters ssse3 functions, and let jump table to choose based on CPU type.
improve vpx_filter_block1d* based on replace paddsw+psrlw to pmulhrsw
Make set_reference control API work in VP9
Moved the API patch from NextGenv2. An example was included.

use by both vp8 and vp9.

Use regular extended zero bin quantizer for both inter and intra
modes in the first pass. This doesn't affect lowres and midres
significantly, but would bring back 0.9% coding gains for hdres.

Originally the uniform quantization function was not being
replaced with the new_quant version in rdopt when new_quant
is turned on. This fixes the bug.

1. Add "best_mv" in MACROBLOCK to store the best motion vector
during motion search, so that we don't need to pass its pointer
to various motion search functions.
2. Declare some functions as static when possible.

Fixed best error reported by loop filter selection, this value is used
