d9d9fd9446 avcodec/error_resilience: Optimize motion recovery code by using blcok lists 
This makes the code 7 times faster with the testcase from libfuzzer
and should reduce the amount of timeouts we hit in automated fuzzing.
(for example 438/fuzz-2-ffmpeg_VIDEO_AV_CODEC_ID_RV40_fuzzer)

The code is also faster with more realistic input though the difference
is small here as that is far from the worst cases the fuzzers pick out

data to make it consistent given the same AC-3 frame, if option is set.

bdbbb8f11e Merge commit 'f450cc7bc5' 
* commit 'f450cc7bc5':
  h264: eliminate decode_postinit()

Also includes fixes from 1f7b4f9abc and e344e65109.

Original patch replace H264Context.next_output_pic (H264Picture *) by
H264Context.output_frame (AVFrame *). This change is discarded as it
is incompatible with the frame reconstruction and motion vectors
display code which needs the extra information from the H264Picture.
