I will continue on the WIP patch Paul posted earlier and try to fix this.
32-bit encoding still has many lossless failures, so keeping it disabled for
now. Will work on it later.

huff offset wasn't always within the bounds before, which lead to
corrupt encoding that didn't always trigger lossless check failures

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.
