avformat/avformat: Deprecate AVFMT_ALLOW_FLUSH
It is of no value to the user, because every muxer can always be flushed with a NULL packet. As its documentation shows ("If not set, the muxer will not receive a NULL packet in the write_packet function") it is actually an internal flag that has been publically exposed because there was no internal flags field for output formats for a long time. But now there is and so use it by replacing the public flag with a private one.
