avio: add a destructor for AVIOContext

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

avformat/mov: prevent duplication of first fragment's ctts_data

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.

avformat/mov: Bail when invalid sample data is present.

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.

avformat/concatdec: add fallback for calculating file duration

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.

avfilter/af_surround: make volume configurable for front center and lfe channel

ffmpeg options: Enable trailing ? for map_channel

The -map option allows for a trailing ? so that an error is not thrown if
the input stream does not exist.
This capability is extended to the map_channel option.
This allows a ffmpeg command not to break if an input channel does not
exist, which can be of use (for instance, scripts processing audio
channels with sources having unset number of audio channels).
