  libfdk-aac: Don't use defined() in a #define
  
  MSVC expands the preprocessor directives differently, making the
  version check fail in the previous form.
  
  Clang can warn about this with -Wexpansion-to-defined (not currently
  enabled by default):
  warning: macro expansion producing 'defined' has undefined behavior [-Wexpansion-to-defined]

  Revert "decode: copy the output parameters from the last bsf in the chain back to the AVCodecContext"
  
  This reverts commit 662558f985f50834eebe82d6b6854c66f33ab320.
  
  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 produces crashes in
  some library users like Firefox.
  Revert until a better solution is found to internally propagate the filtered
  extradata back into the decoder context.
