Add Daala entropy coder.
Move the av1_indices_from_tree() function from av1/encoder/treewriter.c
to aom_dsp/prob.c so that it can be used by both the encoder and
the decoder.

Without first including ./aom_config.h in aom_dsp/prob.c the memmove
function is implicitly defined and causes a compiler warning.
Change-Id: I339d0389f10324a1085aba7d6492b2159a14da92
Added aom_write_tree_cdf() and aom_read_tree_cdf() function calls to
bitwriter.h and bitreader.h respectively.
These calls take a multisymbol CDF and an index and directly encode the
symbol using the enabled entropy coder.
Currently only the daala entropy encoder supports this (enabled with
--enable-daala_ec) and a compile error is thrown otherwise.
Change-Id: I2fa1e87af4352c94384e0cfdbfd170ac99cf3705
Add the av1_tree_to_cdf() macro which takes a aom_tree_index tree and
associated aom_prob probabilities and constructs a daala uint16_t cdf.
The av1_tree_to_cdf_1D() and av1_tree_to_cdf_2D() apply av1_tree_to_cdf()
across 1D and 2D arrays respectively.

When building with --enable-daala_ec, calls to aom_write_tree() and
aom_read_tree() will convert a aom_tree_index structure with associated
aom_prob probabilities into a CDF on the fly for use with the
od_ec_encode_cdf_q15().
The number of symbols in the CDF is capped at 16, and trees that contain
more than 16 leaf nodes are handled by splitting the most likely, e.g.,
highest probability symbols, first and coding multiple symbols if
necessary.

When building with --enable-daala_ec, calls to aom_write() and aom_read()
use the daala entropy coder to write and read bits.
When the probability is exactly 0.5 (128), then raw bits are used.

(cherry picked from aom/master commit af98507ca9)
- 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%.

Instead of having CLPF write to an entire new frame and
copy the result back into the original frame, make the
filter able to work in-place by keeping a buffer of size
frame_width*filter_block_size and delay the write-back
by one filter_block_size row.
This reduces the cycles spent in the filter to ~75%.

- Unit tests are added for AVX2 SIMD.
- Encoder speed improvement:

800 Kbps, 2 Mbps, 6 Mbps, on i7-6700 CPU, average
user level time reduction: 3.86%.

(cherry picked from commit 9dd0b89824)
Includes a major refactoring/enhancement to support
tile-adaptive switchable restoration. The framework can be
readily extended to add more restoration schemes in the
future. Also includes various cleanups and fixes.
Specifically the framework allows restoration to be conducted
on tiles such that each tile can be either left unrestored, or
use bilateral or wiener filtering.
There is a modest improvemnt in coding efficiency (0.1 - 0.2%).
Further enhancements will be added subsequently to improve coding
efficiency and complexity.

When the experiment is ON, we use Paeth predictor instead of TM
predictor.
For derf set, this gives about 0.09% improvement overall, and 0.55%
improvement if all frames are forced to be intra-only.
Also, if the EXT_INTRA experiment is also on, the improvement overall
is 0.056%, and improvement if all frames are forced to be intra-only is
0.465%.
