Andreas Rheinhardt d2bc039501 avcodec/error_resilience: Make applying decode_error_flags optional ...

Add a pointer parameter that if supplied will be used to return
the updated decode_error_flags. This will allow to fix several
races when using frame-threading; these resulted from AVFrame
that the earlier code updated concurrently being used as source
in an av_frame_ref() call in the decoder's update_thread_context.
