On average no compression performance changes. Encoding speed is
increased by 10~20% on some test clips in the derf set.

Drop some speed features used in speed 2 and above, during the
algorithm development process. This helps simplify the codebase.

This computation should match the code in encode_block
to increase the accuracy of the rd optimization.

When built with var_tx and ext_tx, select_tx_size_fix_type is used
to compute the cost for using a particular tx_type.
The code indexes the array inter_tx_type_costs at the wrong location
resulting in a zero cost for signalling tx_type for rect_tx blocks.

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().

Move computing the partition_cdf tables per symbol to
computing them only when the probabilities are updated.
Change-Id: I442f9230ba00be7f5d0558d7c38d7324ad009ee8

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.
