Ping.

We discussed this a bit on IRC and people are open to adding this, but
the question is whether we should re-add the old option during this ABI
unstability period, or whether AVOptions on specific protocols makes
more sense.

My gut says re-adding to AVIO, since AVOptions on specific protos seems
kinda weirdly specific/restrictive, but my opinion is not a stong one.

Any comments or opinion? If not, I'll send a v2 which adds it to AVIO.
