- Same googletest release (v1.8.0), new root in third_party.
- Update Android.mk and make build (include and file locations).
- Update cmake build (use googletest's cmake support).
- Update gtest include in all tests.

Change-Id: I5491a2ff3c8869263cd885872c815402236c20b1
- Wrap functions hidden by CONFIG_MOTION_VAR properly in test code.
- Add some missing ampersands.
Change-Id: Ie7c4e1f14cbacec1c157c7ce110b01350b2ed78e
- Change FDCT32x32_2D_AVX2 output parameter to tran_low_t.
- Add unit tests for CONFIG_AOM_HIGHBITDEPTH=1.
- Update TODO notes.
BUG=webm:1323
Change-Id: If4766c919a24231fce886de74658b6dd7a011246
- Use range check function to avoid DCT_DCT overflow.
We need to re-develop the column txfm side scaling/rounding. Now,
we prefer to maintain the current BDRate level.
- Encoder user level time reduction <1% owing to av1_fht32x32_avx2.
- Add MemCheck unit test and fdct32() unit test.

- av1_fht32x32 AVX2 function level time reduction ~89% compared to C.
- av1_fht32x32_avx2() on DCT_DCT improves 42.62% over aom_fdct32x32_avx2()
But function replacement must go with the corresponding inverse txfm.
- No obvious user level time reduction due to 32x32 TX_TYPE selection.
- Zero high 128b YMM to avoid AVX-SSE transition penalties
(fix 16x16 case).
- Added 32x32 AVX2 unit tests to verify bitexact.
- AVX2 optimization summary:
On CPU i7-6700, based on 16x16/32x32 fwd txfm optimization results:
C to AVX2: function level time reduction, ~86-89%.
SSE2 to AVX2: function level time reduction, ~51%.
