This is a series of patches to allow proper decoding of ogg metadata in chained
`ogg/vorbis, `ogg/flac` and `ogg/opus` streams.
FATE samples for the new tests can be found here: https://www.dropbox.com/scl/fo/xrtrna2rxr1j354hrtymq/AGwemlxHYecBLNmQ8Fsy--4?rlkey=lzilr4m9w4gfdqygoe172vvy8&dl=0
## Changes since last version:
* Fixed fate test run in cross-compiled environments.
* Switched to av_tree to store pending metadata as pts->metadata
mappings in case packets arrive in non-linear order or metadata
updates are split accross multiple packets for a single frame.
Romain Beauxis (8):
libavcodec/decode.c: intercept `AV_PKT_DATA_METADATA_UPDATE` packet
extra data, attach them to the next decoded frame with the same PTS.
tests: Add stream dump test API util.
tests: Add chained ogg/vorbis stream dump test.
libavformat/oggdec.h, libavformat/oggparsevorbis.c: Factor out vorbis
metadata update mechanism.
libavformat/oggparseflac.c: Parse ogg/flac comments in new ogg
packets, add them to ogg stream new_metadata.
tests: Add chained ogg/flac stream dump test.
libavformat/oggparseopus.c: Parse comments from secondary chained
streams header packet.
tests: Add chained ogg/opus stream dump test.
