Oh right, I forgot the "why": to move ASF's packet_size value into
AVFormatContext, it needs to be unsigned. You requested that, since
ASFContext->packet_size is unsigned, but AVFormatcontext->.. is
signed, therefore moving the value from one to the other is a
potential security risk. We both then agreed it was silly that
AVFormatcontext->.. was signed anyway, since any value <0 is
meaningless, and thus here's my attempt to make it unsigned.
