Jonas Ådahl 2731f0cda4 wayland: Setup and use ownership chains
As elsewhere, make sure objects that need to have a ownership up to the
context, and use this ownership chain to find relevant components, such
as the backend or the Wayland compositor object instance.

wayland/data-device: Hook up data devices to seats

They are tied to a seat - make that connection in struct fields too, so
that related objects can get to the context via it.

wayland: Don't get Wayland compositor via singleton getter

This means via the ownership chain or equivalent.

xwayland: Hook up manager to Wayland compositor

Same applies to the drag-n-drop struct.

xwayland: Make X11 event handling compositor instance aware

This avoids finding it via singletons in the callee.

xwayland: Don't get Wayland compositor from singleton

xwayland: Pass manager when handling dnd event

window/xwayland: Don't get Wayland compositor from singleton

xwayland/grab-keyboard: Don't get backend from singleton

xwayland: Don't get backend from singleton

wayland: Always get the backend from the context

This means traveling up the ownership chain or equivalent when
necessary.

wayland: Hook up data devices, offers and sources to the compositor

This allows tying them to a context without going through any
singletons.

wayland: Don't get display from singleton

xwayland: Don't get display from singleton

tablet: Don't get display from singleton
