Merge commit '8c02adc62d71dfbb079a04753d8c16152c49de88'

* commit '8c02adc62d71dfbb079a04753d8c16152c49de88':
  lavu: add all color-related enums to AVFrame

Conflicts:
	libavcodec/avcodec.h
	libavutil/frame.c
	libavutil/frame.h
	libavutil/version.h

The version check is changed so they are available with the current ABI
FFmpeg libs should have no problems with added fields, nor should any
application using the libs, and we regularly added fields in the past.
We also moved 2 of these fields to AVFrame already previously without issues.

See: a80e622924c89df69fb1c225ba432fe12fe6648e
