* Drop trailing spaces * Add a QuantizationContext to cache tx_scale, quantization and offset Speedups compared to the baseline TX_4X4, 20 1.32% TX_4X4, 55 1.55% TX_8X8, 20 -0.08% TX_8X8, 55 0.02% * Convert integer divide into equivalent multiply and add operations Speedup compared to the baseline TX_4X4, 20 0.52% TX_4X4, 55 0.37% TX_8X8, 20 2.90% TX_8X8, 55 3.20% * Pre-generate the multiply-add values for the integer division Speedup from the baseline: TX_4X4, 20 0.66% TX_4X4, 55 0.85% TX_8X8, 20 3.51% TX_8X8, 55 3.66%

Clean up CDFs.
-
This is "Plan B".
-
Which includes both tile group header and tile data.
-
TODO: Need to fix writing the size of OBU_FRMAE payload in obu header, which is the sum of obu_tile_gropu and a tile.
-
So that it can be used for both show_existing case and tile (group) case. TODO: Add write_tile_group_header() for each tile group.

-
Both OBU_FRAME or OBU_FRAME_HEADER obu types call this function.
-
Write the length of OBU payload between a OBU header and a OBU payload, which introduces two byte buffers and BitWriters at the same time. TODO: - Do similar thing for Frame OBU - Can better factor out the code which does post-writing of the length of OBU payload data. - Multi buffer approach, that is rust dependent, can be improved.
-
The uleb size is the size of length field in bytes. https://aomediacodec.github.io/av1-spec/#leb128 TODO: - Include uncounted sequence syntax data to seqence payload size. - Implement uleb128()
-
Also, add trailing bits for sequence OBU.
-
For each frame, write a OBU_TEMPORAL_DELIMITER, even before OBU_SEQUENCE_HEADER or OBU_FRAME_HEADER.
-
Enable OBU Headers, also use the most recent code of libaom, so that rav1e generated bitstream can be decodable by current version of aomdec. - Add OBU_Type enum - write_obu_header() funcion - Copy reference av1_pack_bitstream() C code fro libaom, where sequence and frame level OBUs are written. [OBU] Add Sequence Header and revise its functions [OBU] More on sequence header functions and types - Revise the type of Sequence struct members. - Add write_sequence_header2(), which is modified version of write_sequence_header() for OBU. - Add new color_config(), i.e. updated color info. TODO: - The structure of OBU is three parts: 1) OBU header 2) Size of OBU (written in leb128() format of AV1) 3) OBU (with specific obu_type signlaed in OBU header) So, need to figure out how to post-write the size of obu (i.e, payload size) after writing obu. In libaom, this is implemented by calling obu_memmove() on byte buffer, which moves the obu data by payload size in bytes to create a gap between obu header and obu then write a obu size.

Fixes ./build.sh since README.md now includes more references to cmake.

Fix #307.

Previously we built encoder objects directly in build.rs with cc, but now build them with CMake just like the common and decoder objects. This also removes the duplicate aom_build/*.h files.
