If some previous subtitles are overlapping with the current time
we make sure they are raised so the renderer can display them too.

This function is almost identical to lavf/assdec:read_seek2(). It
performs a generic seek for text subtitles demuxers for the new seeking
API.

The only difference with assdec:read_seek2 is the ts_diff being
unsigned to avoid overflows.

The seek callback in the ASS demuxer will be removed when it is
redesigned to use FFDemuxSubtitlesQueue.

avformat_seek_file() is the new API. It will make sure the read_seek2()
callback is called when the demuxer has it.
