avformat/matroskaenc: Add check for using explicit TrackNumber
When creating DASH streams, the TrackNumber is externally prescribed and not derived from the number of streams in the AVFormatContext, so if the number of tracks for a file using an explicit TrackNumber was more than one, the resulting file would be broken (it would be impossible to tell to which track a Block belongs if different tracks share the same TrackNumber). So disallow this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
