It makes no sense to return an error after the first reconnect, and then somehow resume the next time it's called. Usually this will lead to demuxer errors. Make reconnecting block instead, until it has either successfully reconnected, or given up. Also make the wait reasonably interruptible. Since there is no mechanism for this in the API, polling is the best we can do. This behaves roughly the same as other interruptible network functions in libavformat. (The original code would work if it returned AVERROR(EAGAIN) or so, which would make retry_transfer_wrapper() repeat the read call. But I think having an explicit loop for this is better anyway.) I also snuck in a fix for reconnect_at_eof. It has to check for AVERROR_EOF, not 0.
