Hui Su eafb2e62ac Skip 4x4 transform if maximum possible transform is 32x32
On average no compression performance changes. Encoding speed is
increased by 10~20% on some test clips in the derf set.

Jingning Han 3f16725ff2 Take out some early termination speed features
Drop some speed features used in speed 2 and above, during the
algorithm development process. This helps simplify the codebase.

Peter de Rivaz b85a5a7eac Correction to costing rect_tx
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.

 the od_ec_enc_tell(), od_ec_enc_tell_frac(), od_ec_dec_tell(), and
 od_ec_dec_tell_frac() functions.

Nathan E. Egge f3035f2bc7 Revert code formatting of OD_UNIFORM_CDFS_Q15.
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.

Yushin Cho 09de28b4f7 Bug fix in super_block_uvrd().
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().

Nathan E. Egge cfb02ddcad Add code to compute in-order mappings for tokens.
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.

Nathan E. Egge 44460148b2 Add API for writing trees using a CDF.
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.

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.

Nathan E. Egge 43acafdee2 Use Daala entropy coder to code trees.
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.
