As per the spec:

So a buffer age of 1 means that the buffer was used in the last frame.
We were handling buffer_age==1 the same as buffer_age==0, i.e. we
returned the full damage for the surface.

When we decide to fall back because the settings portal
is not present, adhere to that decision elsewhere. And
treat the fontconfig-timestamp like the other special-cased
settings, with G_TYPE_NONE.
Under Wayland, we are currently directly using GSettings
for desktop settings. But in a sandbox, we may not have
access to dconf, so this may fail. Use the new settings
portal instead.
As GSettings now supports session-specific defaults, GNOME Classic
no longer uses a separate schema and the decoration layout is always
determined by the regular schema.
This essentially reverts commit add67b516c (although the code was
moved since then).

Let's just use the fact that a window was mapped as a subsurface to
remap it above another transient parent instead of relying on the more
complicated 'should-map-as-subsurface' helper function.
GLib master propagates argument types in g_clear_pointer(), which causes
the usual function pointer casts to GDestroyNotify to trip compiler
warnings. Additionally, this commit changes some cleanup functions where
appropriate (wl_data_source_destroy ->
gtk_primary_selection_source_destroy for struct
gtk_primary_selection_source).
Change GdkDrag::action to GdkDrag::selected-action, which is
more clearly different from actions, and follows the existing
name of the struct field and getter.
This lets us drop the ::action-changed signal for the
property change notification. But, can just as well move
the signal class handers which just update the cursor
to the ::action setter. No need to do this in the backends.
Rename gdkdnd.h to gdkdrag.h, to go along with gdkdrop.h
This commit includes the necessary updates to the X11, Wayland
and Broadway backends. Other backends have to be updated separately.
This is to go along with the newly introduced GdkDrop.

Also update the cursor surfaces of every seat when an output changes
scale. This could for example happen when a monitor scale is changed via
Settings.
This functionality is similar to Linux's memfd. It creates anonymous shared memory without touching the filesystem, which allows it to work in Capsicum capability mode (sandbox).
In particular, this patch removes:
gdk_surface_get_events()
gdk_surface_set_events()
gdk_surface_get_device_events()
gdk_surface_set_device_events()
Event masks so far still exist for grabs.
