When the position or size of a fullscreen surface changes (e.g., due to change
in the output), the surface commit logic in desktop_surface_committed() resets
the fullscreen by first calling unset_fullscreen() and later on calling
shell_configure_fullscreen(). One part of this reset is the recreation of the
black view curtain (destroyed in unset_fullscreen() and created again in
shell_configure_fullscreen()).
In the upcoming commit we will replace the call to shell_configure_fullscreen()
with a call to activate() (since we want to activate this shell surface, and
activate() already has a call to shell_configure_fullscreen() in it).
The code in activate() by default lowers the fullscreen layer of the shell
surface through lower_fullscreen_layer(), which is called before
shell_configure_fullscreen(). This lowering function assumes that the fullscreen
shell surface has a valid black view curtain, which as said before was removed
in the call to unset_fullscreen(). Add the check to guard against this case.

During interactive resizes, we progressively change the size of the
client surface and send config events with these sizes to the client.
After that, the toplevel->pending.size keeps the size of the last config
event that we've sent, i.e. the surface size after the resize is over.
Later, if the client spontaneously resize (by attaching a buffer with a
different size or setting the viewport destination, for instance), their
surface size will change, but toplevel->pending.size continues being
that old size from after the resize. If something happens and Weston
decides to send a config event, clients may re-allocate to that old
size, resulting in a sudden resize.
This does not happen when a client goes from fullscreen/maximized to
windowed mode because in such cases we are resetting
toplevel->pending.size to zero. So in the next config event that clients
receive they are allowed to attach buffers with the size that they
prefer.
So do the same after a resize: set the pending config size to zero.

Every shells have an implementation of weston_desktop_api structures.
It includes some callbacks to listen to xdg_surface signals. Committed callback
is one of them.
Currently, the xdg_shell don't invoke the weston_desktop_api->committed
callback when the xdg_surface is initial stage or no surface content.
In the case: the client attached a null buffer after the valid buffer,
the shell isn't going to invoke to xdg_surface committed, and don't know
the surface is disappeared. If the surface is fullscreen, we will get
a black background on the screen until a new valid frame come. That
should not happen.

In commit d611ab24fd "libweston: Update
view transforms more often", a call to weston_view_update_transform()
was introduced to desktop_surface_committed(). It was added between the
point in which we call unset_fullscreen() and
shell_configure_fullscreen(), right after the view geometry dirty bit is
set.
There's a scenario with dual displays in which this change resulted in
the surface being alternated between two outputs:
---
Dual display configuration:
1st display: DP1, with scale 1 - origin 0, 0
2nd display: DP2, with scale 2 - origin 1920, 0
We start the app with the cursor on DP2. Function
desktop_surface_committed() gets called a few times, and it ends up
setting shsurf->saved_x and shsurf->saved_y to the origin of DP2.
Application wants to become fullscreen on DP1, so when the surface gets
committed again and desktop_surface_committed() gets called, we have the
following sequence:
desktop_surface_committed():
was_fullscreen = shsurf->state.fullscreen
is_fullscreen = weston_desktop_surface_get_fullscreen()
if (!weston_surface_is_mapped(desktop_surf))
map(shell, desktop_surf)
return;
/* POINT A, this is important for understanding the issue. */
if (shsurf size didn't change and
fullscreen state didn't change)
return;
if (was_fullscreen)
/* This function calls weston_view_set_pos(saved_x,
* saved_y), and the saved position is the origin of
* DP2. Then it invalidates the saved position */
unset_fullscreen(shsurf)
if (is_fullscreen && !shsurf->saved_position_valid)
/* Saves the position (as it just have been
* invalidated), which will be the origin of DP2
* again. */
shsurf->saved_x = shsurf->view->geometry.x
shsurf->saved_y = shsurf->view->geometry.y
shsurf->saved_position_valid = true
/* This function calls weston_view_assign_output(), which then
* calls weston_surface_assign_output(). The effect of these two
* functions is that the view gets assigned to an output, and to
* choose the output it takes into consideration the position in
* which it is and the area that it occupies on the output. As
* the view has been moved to the origin of DP2, it gets
* assigned to this output. Then Weston sends the enter/leave
* surface events. */
weston_view_update_transform()
if (is_fullscreen)
/* This function positions the view on DP1, because
* that's the output in which the wine app wants to
* become fullscreen. */
shell_configure_fullscreen(shsurf)
/* Now we call weston_view_update_transform() again to each view
* of the surface, and so we end up sending enter/leave surface
* events. But notice that now we are positioned on DP1. */
wl_list_for_each(view, &surface->views, surface_link)
weston_view_update_transform(view);
The next time the surface gets committed and desktop_surface_committed()
gets called, the same sequence will happen. So we'll continue in this
weird loop.
The reason why the surface size changes and we don't return in POINT A
in this scenario is because the application uses a viewport, and then
when its surface moves to the output with scale 2 it sets the surface
size to half its size. That happens for apps that want to keep a
reasonable DPI on scaled displays.
This only happens after the change that introduced the call to
weston_view_update_transform() in this function. Without this call we'd
not reposition the view on DP2 and send enter/leave events at that
point.
---
So in order to avoid that, be more careful before calling
unset_fullscreen() and then shell_configure_fullscreen(). Only do that
when:
- the surface was not fullscreen, and now it becomes.
- the surface was fullscreen, but now it becomes fullscreen on a
different output.
In order to be consistent, do something similar to the maximized state.

This introduces a few getters to retrieve the pending state from
libweston-desktop, now just libweston, and makes use of it,
specifically get_pending_maximized to avoid sending invalid
dimensions to the client in the particular use case
set_maximized/unset_fullscreen.
These pending state getters are useful to query/poke a not-applied
yet state, and could be useful where we don't have a buffer attached
where the client might be set-up as maximized, but internally libweston
hasn't yet applied that pending state.

We do not migrate the weston_curtain destruction from
desktop_surface_removed() to desktop_shell_destroy_surface() because
we'd want have the curtain removed before the animation starts.
If we were to move the black view destruction, *and* only handle it from
desktop_shell_destroy_surface() the animation runs but the black curtain
will be removed right at the end, effectively diminishing the effect of
the animations.
To this end, we keep both of the two worlds, if the client terminates on
its own, we keep the same animation effect, but if the compositor is
shutting down we destroy it immediately.
We remove wl_list_for_each_safe() and instead loop each time to avoid
using a stale pointer iterator which could cause a UAF as the shsurf
would be free'ed.

This patch re-introduces it to avoid leaking the view upon compositor
shutdown, but it does it in tandem with weston_desktop_surface_unlink_view(),
(which was added in a later patch) and before weston_surface_unref() call.
This way we should be safe to terminate/close clients with additional views
created by libweston-desktop (pop-ups), but also in other different situations.
Verified it in the following circumstances:
- terminating a client with close animation on
- terminating a client with close animations off
- shutting down the compositor with clients running, with and
without close animations
- terminating top-level clients with additional pop-ups with both with
and without close animations
