lavf: move AVStream.info to AVStreamInternal

Browse Source 
This struct is for internal use of avformat_find_stream_info(), so it
should not be exposed in public headers. Keep a stub pointer in its
place to avoid changing AVStream layout, since e.g. ffmpeg.c accesses
some fields located after it (even though they are marked as private).
