This adds hdr_meta field in weston_output_color_outcome. This field is intended to be set by color manager modules, and read by backends which will send the information to the video sink in SMPTE ST 2084 mode a.k.a Perceptual Quantizer HDR system. Such metadata is essential in ST 2084 mode for the video sink to produce a good picture. The validation of the data and the group split is based on the HDR Static Metata Type 1 definition in CTA-861-G specification. Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
