Pointers to specific entries in the array are stored in other structs, so
in the scenario where heif_item was reallocated when parsing an iloc box after
and iinf one, the pointers may end up referencing freed memory.
Fixes use-after-free with such samples.

The demuxer's 'missing_streams' private option is used to communicate
information from the demuxer to avformat_find_stream_info(). However,
that is not only unnecessarily complicated, it also leaks internal
information to users, e.g. this option appears in the results of the
fate-flv-demux test.
Use a new field in FFFormatContext to communicate this information
instead.
This function would otherwise fail to build on the next major bump, as
inject_global_side_data is marked for removal.
It should also never be needed, as there is now a mechanism for
supplying global side data to decoders directly.
md5 values change because the nut container now reports rawvideo as encoder
and Y410 as codec type instead of the bogus RGB[15].

If 'sname:*' is set in the var_stream_map variable, use it as
the NAME attribute for subtitles. This improves the naming of
subtitle streams in HTML players, providing clearer and more
descriptive labels for users.

Ensure that when the `-hls_flags omit_endlist` option is set,
the `#EXT-X-ENDLIST` tag is also omitted from the `stream_vtt.m3u8`
subtitle playlist. This maintains consistency with the behavior
in other playlists when `omit_endlist` is specified.

There's no need to keep using a custom decoder for this pixel format.

This basically ignores the overflow without undefined behavior, alternatively we could detect and error out
