This patch set adds support for reading/writing the Matroska BlockAdditionMapping
elements, as well as for reading/writing dvcC/dvvC blocks in Matroska.

Created utility functions to read/write Dolby Vision boxes for ISOM.
This was done to avoid duplicating the code, as the Matroska blocks and MOV boxes
follow the same specification, defined by Dolby.

Refactored the reading/writing in mov/movenc to use the new dovi_isom functions.

Differences compared to v6:
  - Dropped the avformat/mpegts patch as suggested, because the specification
    is different from the ISOM specification defined by Dolby.
  - Added a patch to refactor avformat/movenc to further reduce the duplicated
    code. The implementation in dovi_isom is the same.
  - Moved init_put_bits after the size validation in ff_isom_put_dvcc_dvvc.
  - Added dvwC to the ff_isom_put_dvcc_dvvc logging.

quietvoid (4):
  avformat/dovi_isom: Implement Dolby Vision configuration
  avformat/matroska{dec, enc}: Parse BlockAdditionMapping elements
  avformat/mov: Refactor mov_read_dvcc_dvvc to use
  avformat/movenc: Refactor mov_write_dvcc_dvvc_tag to use
