220b24c7c9 lavc: remove libschroedinger encoding and decoding wrappers 
The library has stopped being developed and Debian has removed it
from its repositories citing security issues.
The native Dirac decoder supports everything the library has and basic
encoding support is still provided via the native vc2 (Dirac Pro, intra
only version of Dirac) encoder. Hence, there's no reason to still support
linking to the library and potentially leading users into security issues.

ca6776a993 avcodec/libfdk-aacdec: Correct buffer_size parameter 
the timeDataSize argument to aacDecoder_DecodeFrame() seems undocumented and until
2016 04 (203e3f28fbebec7011342017fafc2a0bda0ce530) unused.
after that commit libfdk-aacdec interprets it as size in sample units and memsets that on error.
FFmpeg as well as others (like GStreamer) did interpret it as size in bytes

Fixes: 1442/clusterfuzz-testcase-minimized-4540199973421056 (This requires recent libfdk to reproduce)

15bd309af8 movenc: encryption with time code track fix 
instead of deciding whether to encrypt based on the encryption scheme,
decide according to whether cenc was initialized or not.
mov_create_timecode_track calls ff_mov_write_packet with a track that
doesn't have cenc initialized.

ca2209d67a hevc: fix race condition in max_ra/seq_decode. 
These variables are shared between frame threads, but they are updated
post-setup_finished() if a EOB/EOS slice type occurs. Moving the EOB/EOS
slices to the next frame thread instance (by parsing them leading into
the next picture instead of trailing behind the last picture) effectively
prevents this race condition.

This fixes tsan failures on hevc-conformance-NoOutPrior_A_Qualcomm_1.
