This adds an alternate way to use wlr_damage_ring without the
concept of buffer age. Buffer age is a concept inherited from EGL
but there is no real reason why we should continue to use that in
wlroots. Instead, use wlr_buffer pointers.
Eventually, we should be able to remove the buffer age based
functions.
Under X11, ConfigureNotify means that the window has already been resized.
Sending ConfigureRequest with the received size is not only useless, but also
can confuse the window manager, which will probably reply with the current
(i.e. *old*) size causing a configure loop.

new_subsurface emitted immediately isn't actually that useful. Revert the change
and document that this event is special.
This reverts commit 504b9491f0.
This commit changes the behavior of `new_*` signals to better match
their names (see https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3608).
wlr_xdg_shell.events.new_surface is now emitted when an xdg_surface is
created, and wlr_xdg_shell.events.new_{toplevel,popup} events are
introduced to get notified when an xdg_{toplevel,popup} is created.
Same applies to
`wlr_xdg_decoration_manager_v1.events.new_toplevel_decoration`. As a
result, wlr_xdg_surface.added and wlr_xdg_toplevel_decoration_v1.added
are removed, as we no longer need to track whether the corresponding
event was emitted.
Additionally, this commit changes the behavior of
wlr_xdg_surface.events.destroy: it is now emitted when the xdg_surface
is destroyed, as the name suggests.
wlr_xdg_{toplevel,popup}.events.destroy events are added to get
notified when an xdg_{toplevel,popup} is destroyed.
Currently wlr_output holds a wl_display, but it will go away soon.
Instead of relying on that field in wlr_output_create_global(),
make the dependency explicit by taking a wl_display as argument.
wl_display holds a lot more than wlr_session needs: wlr_session
only needs to wait for a FD to become readable, but wl_display
provides full access to the Wayland client and protocol objects.
Switch to wl_event_loop to better reflect the above.
While the xdg-shell protocol requires this, it does not yet have
a dedicated error code for invalid titles; this commit makes
wlroots send a generic error instead.
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.

We can just assume CLOCK_MONOTONIC everywhere.
Simplifies the backend API, and fixes clock mismatches when multiple
backends are used together with different clocks.
This function allows compositors to set the _NET_WORKAREA property on
the root window. XWayland clients use _NET_WORKAREA to determine how
much of the screen is not covered by panels/docks. The property is used
for example by Qt to determine areas of the screen that popup menus
should not overlap (see QScreen::availableVirtualGeometry).
TOKEN_STRLEN is not actually the strlen() of the token. It's the
size taken by the token included the final zero byte.
Change the name to make this clearer, and remove unnecessary +1's.
This flag can be used to figure out whether a particular commit has
unmapped the surface. Private state for now in case we find a better
way to track this.
Translating the right/bottom coordinates from offsets to absolute
coordinates in wlroots (rather than in the compositor) was supposed to
be more reliable, since wlroots had access to the X11 screen size.
It ended up being less reliable, because the screen size values
(xwm->screen->width_in_pixels/height_in_pixels) are not updated when the
output layout changes.
So let's remove the translation from wlroots, and let the compositor
figure it out. From what I can understand of the current XWayland code,
the X11 screen size should generally match the overall wlr_output_layout
bounding box, which the compositor has access to.
