[OBU] Start enabing OBU
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.
