Otherwise the extradata used would be ISOBMFF if the input is
even though we use the *_mp4toannexb BSFs to convert it to
annex B to feed it to the actual decoder.
(The mediacodec decoders also use said BSFs, yet they process
the extradata in a way that works even when using the ISOBMFF
extradata; in fact, using the converted extradata would break
their check for whether to warn for missing extradata for
the ISOBMFF without-in-band-header profiles.
Furthermore, there are several users of the *_mp4toannexb BSFs
that don't ever touch extradata. They have not been touched.)

The aim of this is twofold: a) Clang warns when setting a deprecated
field in a definition and because several of the widely set
AVCodec fields are deprecated, one gets several hundred warnings
from Clang for an ordinary build. Yet fortunately Clang (unlike GCC)
allows to disable deprecation warnings inside a definition, so
that one can create simple macros to set these fields that also suppress
deprecation warnings for Clang. This has already been done in
fdff1b9cbf for AVCodec.channel_layouts.
b) Using macros will allow to easily migrate these fields to internal ones.
