[FFmpeg-cvslog] avformat/utils: Move av_find_default_stream_index to avformat.c

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Sat May  7 07:34:54 2022 +0200| [e00d0ef46d7c4f9763c0482e635b483ff7954104] | committer: Andreas Rheinhardt

avformat/utils: Move av_find_default_stream_index to avformat.c

While it is clearly written with demuxers in mind,
it is not forbidden to call it with muxers, hence avformat.c
and not demux_utils.c.
