Revert "avcodec/decode: copy the output parameters from the last bsf in the chain back to the AVCodecContext"
This reverts commit
f631c328e680a3dd491936b92f69970c20cdcfc7.
The avcodec_parameters_to_context() call was freeing and reallocating
AVCodecContext->extradata, essentially taking ownership of it, which according
to the doxy is user owned. This is an API break and has produced crashes in
some library users like Firefox[1].
Revert until a better solution is found to internally propagate the filtered
extradata back into the decoder context, or a decision is made to change the
API.
