e45f7bca73 lavf/concatdec: properly init streams timestamp parameters. 
pts_wrap_bits defaults to 33 (like MPEG), that causes valid
timestamps to be unwrapped and become invalid.
Inspired by a patch by Wu Zhiqiang <mymoeyard@gmail.com>.

1a0d9b503d 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.

0dcac9c3f0 lavf/concatdec: do not transfer custom IO flag 
If the source is using a custom IO, setting this flag causes heavy leaks
since the segments will not have their avio context closed.

Regression since f5da453b06.

Clearing the extradata is not related to the codecpar change,
and it breaks if auto_convert is disabled.
