avformat: add av_format_inject_global_side_data(), and disable it by default

After this commit applications needs to call av_format_inject_global_side_data()
or handle AVStream side data by some other means if they want it not to be lost.

This fixes a API incompatibility with libav.
libav API does not allow the data to be passed through AVPackets
