This means objects have an owner, where the chain eventually always leads to a MetaContext. This also means that all objects can find their way to other object instances via the chain, instead of scattered global singletons. This is a squashed commit originally containing the following: cursor-tracker: Don't get backend from singleton idle-manager: Don't get backend from singleton input-device: Pass pointer to backend during construction The backend is needed during construction to get the wacom database. input-mapper: Pass backend when constructing monitor: Don't get backend from singleton monitor-manager: Get backend directly from monitor manager remote: Get backend from manager class For the remote desktop and screen cast implementations, replace getting the backend from singletons with getting it via the manager classes. launcher: Pass backend during construction device-pool: Pass backend during construction Instead of passing the (maybe null) launcher, pass the backend, and get the launcher from there. That way we always have a way to some known context from the device pool. drm-buffer/gbm: Get backend via device pool cursor-renderer: Get backend directly from renderer input-device: Get backend getter input-settings: Add backend construct property and getter input-settings/x11: Don't get backend from singleton renderer: Get backend from renderer itself seat-impl: Add backend getter seat/native: Get backend from instance struct stage-impl: Get backend from stage impl itself x11/xkb-a11y: Don't get backend from singleton backend/x11/nested: Don't get Wayland compositor from singleton crtc: Add backend property Adding a link to the GPU isn't enough; the virtual CRTCs of virtual monitors doesn't have one. cursor-tracker: Don't get display from singleton remote: Don't get display from singleton seat: Don't get display from singleton backend/x11: Don't get display from singleton Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2718>
