995d937827 libavcodec/jpeg2000: fix precinct coordinate calculation 
The calculation of precinct boundaries has been
fixed. The precinct boundaries were calculated
as an offset to the band boundary, but must
instead be calculated as an offset from the
reslevel. This patch fixes #4669 and #4679.

e8344f21e1 libavcodec/jpeg2000dec.c: fix error in cod marker 
This patch fixes an error where the COC marker
overrides all data of the SPcod field of the
COD marker. It must override only one bit of
SPcod field. This now allows p0_08.j2k to be
decoded correctly (mentioned in #4679).

12a5e0409d avcodec/ac3_tab: Zero-terminate ff_ac3_sample_rate_tab 
This is required to use it as an AVCodec.supported_samplerates array.
Adding the sentinel has been forgotten in 4679a474.
Without it e.g. the FATE-test ffmpeg-filter_complex_audio fails with ASAN.
