90cfc084e3 avpacket: free side data in av_free_packet(). 
Freeing it in av_destruct_packet(), as is done currently, would mean
that we allow it to be allocated with other means. But that would make
av_packet_new_side_data() unsafe.

Side data is not expected to be large, so copying it if required
shouldn't be a problem.
