Main use-case is proxying avio through a foreign I/O layer and a custom
AVIO context, without losing latency and performance characteristics.

Before this commit, AVIOContext is to be freed with a plain av_free(),
which prevents us from adding any deeper structure to it.

MP4 files with fragments might have the first moof box that is mentioned
in a fragment index before the first mdat box. Since it is then already
parsed by mov_read_header, we have to make sure that mov_switch_root
will not parse it again when seeking by setting the headers_read flag in
the index. Parsing it a second time would cause the ctts_data array to
receive a second copy of the information from the trun box, leading to
wrong PTS values for the second and following fragments in presence of
B-frames.

Fixes ticket 6560.

ctts data in ffmpeg relies on the index entries array to be 1:1
with samples... yet sc->sample_count can be read directly from
the 'stsz' box and index entries are only generated if a chunk
count has been read from 'stco' box.

Ensure that if sc->sample_count > 0, sc->chunk_count is too as
a basic sanity check. Additionally we need to check that after
the index is built we have the right number of entries, so we
also check in mov_read_trun() that sc->sample_count ==
st->nb_index_entries.

If a file does not have a known duration, this leads to the timestamps
starting over for the next file, causing non-monotonic timestamps.
To prevent this, track the duration during demuxing and use it to
determine the current file duration before opening the next file.
