Before we were populating wlr_output.current_mode with a generated
fixed mode when a custom mode was committed in the DRM backend. But
that's no longer the case: now a custom mode behaves the same under
the DRM backend and other backends.
wlr_output_layout was still assuming that an output without a
current_mode was disabled. Fix that assumption.

We have current and pending state and the code uses struct
assignments between them and resets and frees in multiple places.
Introduce a reset() function so we can unify that.
wlr_cursor is responsible for sending enter/leave events, but
doesn't send fractional-scale-v1 and wl_surface.preferred_buffer_scale
events. This is not an easy thing to do from a compositor, so let's
just do it in wlr_cursor itself.
When we cleared the pending backend damage when the output committed,
we would not take into account the output transform. It's easiest to fix
this by just changing pending_commit_damage to always have transformed
coordinates.
Direct scanout damage will just accumulate on the damage ring while in
direct scanout and properly damage when we exit anyway. On the flip side
since we now manage backend damage submission ourselves, this won't break
that either.
Sadly, the new API is not backwards compatible with the old API. Since
we have already switched all users in wlroots to the new API compositors
are already practically mandated to implement the new API. Let's get rid
of the old one since there is no point.
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.
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.
The wl_display destroy listener cleans up the global (if any).
wlr_output.display will go away, so setup the listener in
wlr_output_create_global() instead of wlr_output_init().
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.
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.
We want to call the outputs updated signal when an output scale or transform
changes. Otherwise helpers like the scene surface helpers will not be
notified of scale changes and not pass them to clients.
Since commit 5567aefb, fixed modes haven't been automatically generated
for custom modes, so the output management implementation needs to be
able to handle them directly. To avoid polluting the mode list, only a
single custom mode can be listed at a time and will be removed when a
fixed mode is set.

We can just assume CLOCK_MONOTONIC everywhere.
Simplifies the backend API, and fixes clock mismatches when multiple
backends are used together with different clocks.
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.
A layer-shell surface can be unmapped if wlr_layer_shell_v1 is
destroyed or the client has committed a NULL buffer. Let's use the
previously introduced wlr_surface.unmap_commit to handle the latter
case instead; this is more consistent with the xdg_surface
implementation logic, where using the hook is more trouble than it's
worth.
Additionally, this commit adds an unconditional surface reset on
destroy, so popups are properly cleaned up even if originally created
with an unmapped layer-shell surface as a parent. Doing so with the
role unmap hook would either result in possibly resetting the surface
twice, which is suboptimal, or having an awkward
`if (mapped) { unmap() } else { reset() }` check.
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.
The name "allow_artifacts" and associated description is very vague, and
theoretically allow for tearing behavior. Clarify that we only intend to
mean artifacts related to output configuration (e.g., modesets).

There were a couple of problems with this:
1. The behavior is unexpected. Typically objects in wlroots won't
also destroy objects that they depend on. For instance, wlr_scene_output
will not destroy the wlr_output when it's destroyed. It shouldn't be any
different for scene layouts.
2. This fixes a crash where because wlr_output_layout and wlr_scene_output
are both addons to wlr_output, we might get into a situation where
wl_list_for_each_safe might malfunction. See [1]
This means that the compositor needs to manually destroy the output
when they destroy the layout, hence ~breaking. Compositors can just
call `wlr_scene_output_destroy()` if they want to destroy both at the
same time.

It makes little sense to have a catch-all grab vaildation function,
considering that e.g. tablet tool implicit grabs are possible as well.
Besides, the function has always returned true anyway.
Since headless and wayland-without-presentation-feedback were firing
present inside their commit impls, present was getting fired before
commit, which is cursed. Defer this with an idle timer so that commit
handlers can run before present handlers.
This fixes a crash in the case where the last cursor was a client surface
cursor but then transitioned into a server managed xcursor that isn't
available. Because the logic would return early before, we would continue
to reference a texture pointer belonging to a client surface but would
otherwise disassociate with it (we wouldn't clear the cursor if the surface
is destroyed) resulting an an eventual UAF.
Let's just make the cursor invisible if we don't know what to show. It's
compositor policy if they want to show a default.
