mutter/src/wayland/meta-wayland-text-input.c
Michel Dänzer 6379e54847 wayland/surface: Prepare for decoupled surface & resource lifetimes 
Need to deal with surface->resource == NULL and
surface->pending_state == NULL in some places.

v2:
* Avoid expanding conditions to multiple lines.
  (Georges Basile Stavracas Neto)
v3:
* Use a single bailout condition in meta_wayland_client_owns_window as
  well.
v4:
* Remove spare empty line in meta_wayland_surface_apply_state.
  (Robert Mader)
* Add wl_resource_post_error calls in xdg-shell request handlers.
  (Robert Mader)
* Drop checks in functions which can only be called if there's a valid
  resource.
* Drop more checks which are unnecessary due to leaving the
  SURFACE_DESTROY signal emission in wl_surface_destructor later.
v5:
* Move resource = surface->resource assignments to if (!resource) tests.
  (Jonas Ådahl)
v6:
* Fix style issue per check-style.py.
