Tests the parsing and writing of AVDOVIDecoderConfigurationRecord,
when it is present as a Dolby Vision configuration block addition mapping.
Signed-off-by: quietvoid

The required regression test file is available here: https://0x0.st/-hWK.mkv
Should be moved to fate-suite/mkv/dovi-p5.mkv
Improves code legibility by not using bit shifts.
Also avoids duplicating the dvcC/dvvC ISOM box writing code.

Adds handling of dvcC/dvvC block addition mappings.
The parsing creates AVDOVIDecoderConfigurationRecord side data.
The configuration block is written when muxing into Matroska,
if DOVI side data is present for the track.
Most of the Matroska element parsing is based on Plex's FFmpeg source
Both parse/write implementations are based on mov/movenc.
This only adds support for the "Dolby Vision configuration box".
Other configuration boxes, such as
"Dolby Vision enhancement layer configuration box" are not supported.
The new functions will be used to implement parsing/writing the DOVI
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

This fix targets (rare) cases where multiple input pads have a
.filter_frame function. ff_request_frame_to_filter needs
to call ff_request_frame with the correct input pad
instead of the hardcoded first one.

This commit actually enables subtitle filtering in ffmpeg by
sending and receiving subtitle frames to and from a filtergraph.
The heartbeat functionality from the previous sub2video implementation
is retained and applied to all subtitle frames (bitmap, text, ..).
The other part of sub2video
