Unfork ANS decode_coefs
Remove ZERO_TOKEN from the ANS tokenset
Drop costing ANS tokens from derived probabilities
Unfork ANS pack_mb_tokens
Fix a bug in the C implementation of the ihalfright32
transform, in the case that its input and output buffers are the same.
This occurs when it is called by av1_iht32x16_512_add_c.

- 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%.

This can be re-added after aligning AOM's ANS with nextgenv2's ANS.
This partially reverts commit 3829cd2f2f9904572019aa047d068baeee843767.

This mimics what's currently done in aom/master. This can be re-added
after aligning AOM's ANS with nextgenv2's ANS.

This commit renames LIBVPX_TEST_DATA_PATH to LIBAOM_TEST_DATA_PATH,
with a work around for working with jenkins environmnet variables.

Before this change, gm parameters were being written to the
bitstream for all frames, but only read for inter only frames,
causing a bitstream error.

Adds the functionality to return the rate cost due to
coefficients without doing full search of all modes.
This will be subsequently used in various experiments,
including in new_quant experiment to search quantization
profiles at the superblock level without repeating the
full mode/partition search.

* Move clipping tests from inside to outside loops
* Let sizex and sizey to clpf_block() be the clipped block size rather
than both just bs
* Make fallback tests to C more accurate

When CLPF was extended to chroma, the chroma RDO accidentally
discarded the optimal block size found in the luma RDO.

Previously, only the motion vectors were being stored. This caused
a mismatch in the global motion experiment, which needs this
mode information to decide whether or not to use the gm parameters
in reconstruction.

Rename av1_write_tree() to aom_write_tree() and move it into bitwriter.h
to match aom_read_tree() in bitreader.h.

av1_clpf_frame() was always called with the same src and dst,
so we only need one argument and the code supporting different
src and dst was removed.
