backend/drm: introduce wlr_drm_connector_state Previously, we were copying wlr_output_state on the stack and patching it up to be guaranteed to have a proper drmModeModeInfo stored in it (and not a custom mode). Also, we had a bunch of helpers deriving DRM-specific information from the generic wlr_output_state. Copying the wlr_output_state worked fine so far, but with output layers we'll be getting a wl_list in there. An empty wl_list stores two pointers to itself, copying it on the stack blindly results in infinite loops in wl_list_for_each. To fix this, rework our DRM backend to stop copying wlr_output_state, instead add a new struct wlr_drm_connector_state which holds both the wlr_output_state and additional DRM-specific information.

backend/drm: introduce page-flip tracking struct Introduce a per-page-flip tracking struct passed to the kernel when we request a page-flip event for an atomic commit. The kernel will pass us back this pointer when delivering the event. This eliminates any risk of mixing up events together. In particular, if two events are pending, or if the CRTC of a connector is swapped, we no longer blow up in the page-flip event handler.
