backend/drm: take wlr_output_state as arg in crtc_commit Stop assuming that the state to be applied is in output->pending in crtc_commit.

backend/drm: add test_only arg to wlr_drm_interface.crtc_commit Right now callers of drm_crtc_commit need to check whether the interface is legacy or atomic before passing the TEST_ONLY flag. Additionally, the fallbacks for legacy are in-place in the common code. Add a test_only arg to the crtc_commit hook. This way, there's no risk to pass atomic-only flags to the legacy function (add an assert to ensure this) and all of the legacy-specific logic can be put back into legacy.c (done in next commit). 2021-07-08 15:56:01 +02:00			`uint32_t flags, bool test_only);`
