Fixes: u263_b-frames_1.avi
Fixes part of Ticket1536

return -1 is used here as it is used in similar code in this function, I intend
to replace it by proper error codes in the whole function.

Michael Niedermayer 536ac72f46 Revert "Merge commit '0a39c9ac0bfd7345fe676b4e2707d9cec3cbb553'" 
The assumption this is based on is wrong, the code is not always run with bitexact flags

This reverts commit a956164e1e, reversing
changes made to f6005907fd.

This treats the case of no slices like no frames which it basically is.

The field is added to the context as other nal related fields are also there
and passing the has_slices field per *arguments is ugly and not consistent

Michael Niedermayer 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
