AVCodec.channel_layouts is deprecated and Clang (unlike GCC) warns when setting this field in a codec definition. Fortunately, Clang (unlike GCC) allows to use FF_DISABLE_DEPRECATION_WARNINGS inside a definition (of an FFCodec), so that one can create simple macros to set AVCodec.channel_layouts that also suppress deprecation warnings for Clang. (Notice that some of the codec definitions were already inside FF_DISABLE/ENABLE_DEPRECATION_WARNINGS (that were not guarded by FF_API_OLD_CHANNEL_LAYOUT); these have been removed. Also notice that setting AVCodec.channel_layouts was not guarded by FF_API_OLD_CHANNEL_LAYOUT either, so testing disabling it it without removing all the codeblocks would not have worked.)
