Recent encode API restructure (827d6fe73d) removed some state - which broke
the API for flushing without closing the encoder.
This functionality was originally added in 3ea7057677 and is useful for
segmented video, where we don't want to do expensive re-init of HW sessions
for every segment.

This patchset introduces AV_DISPOSITION_URGENT disposition flag for
marking stuffs which is expected to be shown immediately as received,
and adds recognization/remuxing support for ARIB superimpose stream.
ARIB superimpose is almost same as ARIB caption but is utilized to
transmit emergency alert
Recognize ARIB superimpose stream through ARIB data coding descriptor,
and re-use AV_CODEC_ID_ARIB_CAPTION codec id with an extra disposition
flag AV_DISPOSITION_URGENT.

Put the fact that -re is equivalent to -readrate 1 in the deprecated message so
people know what to switch to.
Other than that looks good to me.
