Michael Niedermayer 831274fba4 avcodec/flacdsp: Avoid undefined operations in non debug builds 
This fixes ubsan warnings in non debug builds by using unsigned operations

in debug builds the correct signed operations are retained so that overflows
(which should not occur in valid files and may indicate problems in the DSP code
or decoder) can be detected.

Alternatively they can be changed to unsigned unconditionally, then its
not possible though to detect overflows easily if someone wants to test
the DSP code for overflows.

The 2nd alternative would be to leave the code as it is and accept that
there are undefined operations in the DSP code and that ubsan output is
full of them in some cases.

Similar changes would be needed in some other DSP routines

Michael Niedermayer 25f4f08ba5 avcodec/h264dec: Fix regression with "make fate-h264-attachment-631 THREADS=8" 
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
