Fix recent FFmpeg deprecations

This includes codec/muxer/demuxer iteration (different iteration
function, registration functions deprecated), and the renaming of
AVFormatContext.filename to url (plus making it a malloced string).

Libav doesn't have the new API yet, so it will break. I hope they will
add the new APIs too.
