This commit replaces all uses of sig_peak and maps all HDR metadata.
Form notable changes mixed usage of maxCLL and max_luma is resolved and
not always max_luma is used which makes vo_gpu and vo_gpu_next behave
the same way.
This reworks all of mpv's unit tests so they are compiled as separate
executables (optional) and run via meson test. Because most of the tests
are dependant on mpv's internals, existing compiled objects are
leveraged to create static libs and used when necessary. As an aside, a
function was moved into video/out/gpu/utils for sanity's sake (otherwise
most of vo would have been needed). As a plus, meson multithreads
running tests automatically and also the output no longer pollutes the
source directory. There are tests that can break due to ffmpeg changes,
so they require a specific minimum libavutil version to be built.
