To get ready for pulling AV1 to nextgenv2. Refactoring is done to
make the code structures similar, especially for the motion search
part.

Cherry-pick Daala 211c2a41: Clean up EC tell() and tell_frac() functions.
Add a const qualifier to the od_ec_enc and od_ec_dec parameters of
the od_ec_enc_tell(), od_ec_enc_tell_frac(), od_ec_dec_tell(), and
od_ec_dec_tell_frac() functions.
Add an OD_WARN_UNUSED_RESULT to od_ec_enc_tell_frac().

The formatting of OD_UNIFORM_CDFS_Q15[] in entcode.c is helpful for
for understanding what is contained in the array (e.g., the uniform
probability distributions of small sizes 2 through 16).
This patch reverts the change made in f4b2926d and adds linter hints to
ignore the formatting.

In super_block_uvrd(),if is_cost_valid == 0, all return parameters,
i.e. rate, distortion, skippable, and sse, are reset.
So, should not call txfm_rd_in_plane() if is_cost_valid == 0.
Also, the bug causes av1_xform_quant() to see invalid diff signal
since av1_subtract_plane() is not called in super_block_uvrd().

Display the -b --bit-depth command line parameter on of aomenc when
--config-aom-highbitdepth is enabled.
Change-Id: I76147e38b9985e68b1e642e21be8fd4d8ec4d966
Move computing the partition_cdf tables per symbol to
computing them only when the probabilities are updated.
Change-Id: I442f9230ba00be7f5d0558d7c38d7324ad009ee8
Move computing the inter_ext_tx_cdf tables per symbol to
computing them only when the probabilities are updated.
Change-Id: I5e1e62f8eae8f6b2edbbd378beeb786649502c10
Move computing the intra_ext_tx_cdf tables per symbol to
computing them only when the probabilities are updated.
Change-Id: I26d5e419e103093e98a7d896c196176305b50fc9
Move from computing the switchable_interp_cdf per symbol to
computing once per frame when the probabilities are adapted.

* changes:
Add missing CONFIG_DAALA_EC declaration.
Add API for writing trees using a CDF.
Add macro to build a simple cdf table.
Use Daala entropy coder to code trees.
Silence clang-format code review warning.
Use Daala entropy coder to code bits.
Clear existing format issue in the codebase
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.
Change-Id: Ie43c599f425c3503b1ff93f0c77b5033a05b1bb4
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
Add av1_indices_from_tree() function that computes a forward and inverse
mapping of the tree leaf-node symbols to their in-order traversal.
This is necessary because many of the aom_tree binary trees have their
leaf nodes out of order (e.g., an in-order traversal of a tree with n
nodes does not start at symbol 0 and go to symbol n - 1), but the CDFs
created by tree_to_cdf() are indexed in-order.
Change-Id: Icd0dbed4c171a67c9e84a634106c4fdb5b1b3488
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.
Change-Id: If79fa5ae034263f279d7d0842493570885272fb2
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.

This flag was already added to aomedia/master, so bringing it back to
webm/nextgenv2, as part of an effort to get the two codebases in sync.

This reverts commit 9b25f3067485b32442e13964df098903736c3fd8 to
reinstate the reverted commit with fixes that solved the build issues
when --enalbe-clpf is used in configure.
