[FFmpeg-cvslog] avcodec/textdec: Deduplicate AVClasses

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Mon Jun  7 16:13:33 2021 +0200| [f067795c7486fc230092eeb45c3dd35b7ca612f3] | committer: Andreas Rheinhardt

avcodec/textdec: Deduplicate AVClasses

The child_class_next API relied on different AVCodecs to use
different AVClasses; yet this API has been replaced by
child_class_iterate.
