Tautvis 2d72f9e192 xfree86: ddc: parse CTA-861-G HDR static metadata + colorimetry data blocks ... Add xf86DoInterpretHDRMetadata(), which walks the EDID's CTA/CEA extension data blocks and fills in a new struct monitor_hdr_data (tail-appended field xf86Monitor::hdr) from the two blocks a display uses to advertise HDR support: - the Colorimetry Data Block (tag 5): which extended gamuts/transfer spaces the display accepts (BT.2020 RGB/YCC/cYCC, opRGB, xvYCC, ICtCp, ...), exposed via is_CTA_CDB_*() bit-test macros. - the HDR Static Metadata Data Block (tag 6): supported EOTFs (traditional SDR/HDR gamma, SMPTE ST.2084/PQ, HLG) plus the desired content min/max/max-frame-average luminance, decoded with the CTA-861-G power-law formulas. Covered by a new EDID unit test (test/ddc-tests.c) using real captured EDIDs from four displays (Samsung Q800T, MSI MAG321CURV, HP 27 QD, and a QEMU virtual display as the "no HDR block present" negative case), asserting the parsed colorimetry/luminance values match known-good figures for each. This is a standalone prerequisite for HDR support, independent of any particular rendering-pipeline design: cepelinas9000's HDR work (https://github.com/cepelinas9000/xserver/tree/wip/x11hdrV2) needs to know a display's HDR/colorimetry capabilities before doing anything else, and this is useful on its own for any HDR/wide-gamut detection regardless of how the rest of the pipeline ends up looking. Extracted (with typo/whitespace cleanup, no logic changes) from cepelinas9000's wip/x11hdrV2 branch, commit 159a6f484a, for standalone review ahead of the larger HDR effort. Note for review: struct monitor_hdr_data is added as a new field at the tail of the public xf86Monitor struct (include/edid.h) - additive only, no existing field shifts.
