In case shsurfs are migrated/moved or started on different outputs other
than the default one, it causes fullscreen views to never being demoted
to a lower stacking level, due to the fact we never update
the view's output whenever that has changed.

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

A highly unlikely, but still valid operation, is to close/destroy the
window while still having it grabbed and moved around, basically having
an in-flight destruction of grabbed moving window. Another situation
would be that the client terminates abruptly (crashing for instance),
while being dragged which might take down the compositor.
This could happen for both touch/pointer grab operations and could cause
a NULL pointer access while accessing desktop_surface when being used
to retrieve the underlying weston_surface.
With this patch we check for a valid desktop_surface and return early
if that's not the case.

Creates a distinct view, separated from the one created by
libweston-desktop, in order to avoid a potential ownership fight with
libweston-desktop upon destroying the view. Upon weston_desktop_surface
destruction, libweston-desktop inflicts damage on the view it creates,
so we need the view to be alive at that time.
This wasn't such an issue before because we had different destruction paths but
with commit 'desktop-shell: Do not leave views in layers upon shell
destruction' all of the destruction paths now land in the same spot
+ handle compositor tear down.
Note as we still use the same weston_surface we'll keep the previous
construct where we were taking a reference to keep it alive.
The original view is destroyed when releasing the ownership, while for
the view created in this patch we handle the destruction directly upon
compositor tear down.

Similar to how we do it with drm_fb ref counts, increase a reference
count and return the same object.
Plug-in in desktop-shell when we map up the view in order to survive a
weston_surface destruction.
Astute readers will notice that this patch removes weston_view_destroy()
while keeping the balance between removing and adding a
weston_surface_unref() call in desktop_shell_destroy_surface().
The reason is to let weston_surface_unref() handle destruction on its
own. If multiple references are taken, then weston_surface_unref()
doesn't destroy the view, it just decreases the reference, with
a latter call to weston_surface_unref() to determine if the view
should be destroyed as well. This situation happens if we have
close animation enabled, were we have more than one reference taken: one
when mapping the view/surface and when when the surface itself was created,
(what we call, a weak reference).
If only a single reference is taken (for instance if we don't have close
animations enabled) then this weston_surface_unref()
call is inert as that reference is not set-up, leaving libweston to
handle the view destruction.
Following that with a weston_view_destroy() explicit call would cause a
UAF as the view was previous destroyed by a weston_surface_unref() call.
A side-effect of not keeping the weston_view_destroy() call would
happen when tearing down the compositor. If close animations are enabled,
weston_surface_unref() would not destroy the view, and because
weston_view_destroy() no longer exists, we would still have the
view in the other layers by the time we check-up if layers
have views present.

shell-utils contains a number of helpers which are currently in use by
both desktop-shell and kiosk-shell. In order to extend this use to
fullscreen-shell as well (which can benefit from reusing the
weston_curtain infrastructure to be able to create solid-colour views
which may or may not be opaque, as well as one function within
fullscreen-shell which was copied wholesale to shell-utils), we need to
create a separate Meson dependency object, and avoid the existing
pattern of including the source from shared/ within the source list for
each shell.
This requires creating a new top-level directory for these shared helper
functions which are required by each shell, but are not part of
libweston in and of itself.
shell-utils depends on libweston-desktop; libweston-desktop depends on
libweston; libweston depends on shared.
Thus it is not possible to expose a dependency object from the shared/
directory which declares a dependency on the libweston-desktop
dependency, as Meson processes directories in order and resolves
variable references as they are parsed.
In order to break this deadlock, this commit creates a new top-level
directory called 'shell-utils' containing only this file, which can be
parsed by Meson after libweston-desktop (making the libweston-desktop
Meson dependency variable available to the build file to declare a
dependency on that), but before the shells (making the new Meson
depenendency object available to each shell which wishes to use it).

Use the common infrastructure we have, rather than open-coding again.
In changing to the common weston_curtain infrastructure which was
introduced in a previous commit, there are two small functional
derivations.
After adding the view to a layer, we explicitly call
weston_view_geometry_dirty(). This is believed to have no functional
impact, as weston_views have their geometry-dirty flag set when they are
created.
weston_surface_damage() is also called to ensure that the surface is
scheduled for a repaint. As there is currently no good common mechanic
in the common code to ensure that output repaint will occur, due to the
damage propagating outwards from the weston_surface, we are forced to
call this to predictably ensure that the output will be repainted after
we have made this change to the scene graph which should result in the
user observing the new content being repainted.
It is possible that these changes are not strictly required in order for
the correct behaviour to occur. However, it is felt that explicitly
adding these calls is perhaps the least fragile way to ensure that the
behaviour continues to be correct and breakage is not observed,
especially with both view mapping and surface damage identified as areas
for future work which could be beneficial to Weston. If it is felt that
these calls can be removed, then this is certainly possible at a later
stage.
Lastly, there are many users within desktop-shell of the common pattern
of creating a weston_curtain and inserting it into the scene graph to be
painted. These users have been an area of both theoretical concern and
real-life observed fragility and breakage recently. By making each user
follow a common and predictable pattern of usage, each user is no longer
its own special case. This should make it easier to make the
desktop-shell codebase more robust, not only simplifying the codebase,
but improving observed behaviour.
In doing this, it is hoped that future structural and interface changes
become easier to make, allowing us to improve some of the more difficult
corners of the libweston API.

Just as we do for fullscreen backgrounds, reuse the curtain infrastructure
for focus animations.
This introduces a small functional change, in that the surface's output
is no longer directly assigned. Instead, we call
weston_view_set_output() ourselves. As setting the weston_view's
position (done from the common helper function of weston_curtain_create
which has been introduced in previous commits) will call
weston_view_set_position(), the view's geometry will be dirtied as a
result.
When the geometry of a weston_view is dirty, it is marked to be updated,
which will occur whilst traversing the view list during output repaint.
This occurs for every view which is currently assigned to a layer; when
building the view list, any view reachable through the view list whose
geometry is dirty will have its position recalculated and an output
assigned. Doing so results in the surface's current output being
updated.
It is believed that there is no functional impact from the
weston_surface not having a primary output assigned between creation and
output repaint being called.

Rationalise it a little bit so we don't need pre-declarations of static
functions, and the order of creation more closely matches the others,
including making the same calls to explicitly set the output.
Doing this makes the behaviour match the other users of the same code
pattern. In making them the same, we make desktop-shell code a little
less magically divergent where people might wonder what the correct
pattern is to use. After we have moved all users to a uniform pattern,
later commits are then able to migrate these users to common helper
code, which reduces code duplication, improves code clarity as it is no
longer necessary to wonder about the exact semantics of every
special-case user of this common pattern, and makes it easier to make
interface changes which improve and clarify the patterns which are
prevalent throughout the desktop-shell code.

itself invalid. This wasn't apparent at that time because we're not
handling at that the removal of surfaces from layers.

Attempting to perform a switch on a surface (already) closed will trip
the assert in activate(), so check if we have a weston_desktop_surface
before trying to activate it.

We no longer make use of the keyboard_focus_listener so remove it
entirely.

We shouldn't be constrained by having a keyboard plugged-in, so avoid
activating/de-activating the window/surface in the keyboard focus
handler and embed it straight into the window activation part.

The shsurf is calloc'ed so the surface count is always 0. Not only
that but the surface is not set as active by default, so there's no
need to de-activate it.

When the surface type of input panel is set as an overlay panel, it's
expected to be shown at near the input cursor. But the current
implementation shows it at center-bottom on the desktop at first then
move it to the correct position while typing.

The keyboard focus listener, caps changed and pointer focus listener
were missing when destroying the seat. These are necessary to avoid
using weston_desktop object even if it was destroyed, which happens due
to a focus out event and ultimately handled by the keyboard focus notify
callback.
Once the seats are destroyed (and implictly the focus handlers) we're
safe to destroy weston_desktop object as well.

This properly tracks the seats and with it, destroys them before
destroying weston_desktop object.
