Original issue's description:
> Cast: Fix two video freezing problems
> 
> 1) The first one only happens when running UDP over localhost: The connect() call
>    call fails and the sender stops listening to incoming packets. I fixed this by
>    re-starting the packet listening if needed after each successfully sent packet.
> 
> 2) The second problem is that the packet storage times out packets based on time,
>    with the assumption that no packet should have to be re-sent if it's older than
>    the max history time. However, if packets are not ACKed in a timely fashion, the
>    video_sender may need to re-send arbitrarily old packets. To fix this, I change
>    the packet storage to remember "max outanding frames" regardless of timing.
