cc837eea61 kiosk-shell: Redesign the function 'find_focus_successor()'
The function find_focus_successor() is called when destroying a surface to find
a successor to the current focus. It, however, has the following issues:

- Its first parameter is the weston layer from which to search for a successor.
  This is an unnecessary flexibility for our use, which only adds complexity to
  the user of the function by having to make a call for each layer. We know
  that we want to search for a successor first in the normal layer, and if that
  fails, then in the inactive layer. So we change the signature of
  find_focus_successor(), removing this first parameter.

- It includes logic to decide whether to do the search or not: if the destroyed
  surface is different from the surface that currently has focus, and if their
  outputs are the same, then abort and don't do the search. This returns NULL to
  the calling function. The problem is that the function also returns NULL if
  it does the search and finds no successor. The distinction for the failing
  reason is lost, and the user of the function needs to add more logic to know
  the reason for failure. To simplify, we take the logic out of
  find_focus_successor() and inside the caller.

- It returns the successor view, although it receives surfaces and the client
  has logic to retrieve the surface corresponding to the returned view. To
  simplify and maintain symmetry, we change the signature so that the function
  returns the surface corresponding to the successor view.

d53efc6cc3 kiosk-shell: Distinguish between 'destroy_signal' and 'parent_destroy_signal'
Currently, the 'parent_destroy_listener' is being paired with
'destroy_signal'. The signal is emitted from kiosk_shell_surface_destroy(),
which is the appropriate place to emit this general-purpose surface destruction
signal.

However, we need to inform the children of the surface destruction before
finding the focus successor and activating it, that is, before calling
find_focus_successor() and kiosk_shell_surface_activate(), which happen before
kiosk_shell_surface_destroy().
Since there are currently other uses for 'destroy_signal' (e.g. in
kiosk-shell-grab.c), don't mess with it and simply add a new
'parent_destroy_signal', placing its emition where we need it.

beece0215f kiosk-shell: Handle relinking of surface trees when setting a parent
This commit adds code to maintain the correct order and linking of a surface in
its surface tree list for when a new parent is being set on it.

If the new parent is not NULL, the child might already belong to the same
surface tree as the new parent's root, in which case no relinking is necessary.
Check this by calling kiosk_shell_surface_is_surface_in_tree(shsurf, shroot),
to see if 'shsurf' is in the surface tree list represented by 'shroot', where
'shroot' is the new parent's root surface. In case 'shsurf' doesn't belong to
this surface tree, relink it there.

If parent is NULL, 'shsurf' will become root of a new surface tree list. In
this case 'shroot' is the root surface of shsurf's current surface tree list.
Iterate through the surface tree list of this 'shroot' to relink all
descendents of 'shsurf' into this new list and set it as the new active surface
tree for the output.

1077a8ed9b kiosk-shell: Introduce an "active surface tree" for each kiosk shell output
This commit introduces to the kiosk shell output structure a pointer to a
surface tree list. This pointer will reference the surface tree list currently
active on the output. (Surface tree lists were introduced in the previous
commit)

Each output will have at most one active surface tree. A surface tree being
active on an output means that all views for this output belonging to that
surface tree, and only those views, are in the normal layer.

kiosk_shell_output_set_active_surface_tree() sets the current active surface
tree for the specified output, replacing the previous one.

Set the new active surface tree when first mapping a surface

a1c3c09959 kiosk-shell: Introduce surface tree lists to the kiosk shell
The following patchset implements proper z-order for xdg surfaces in the kiosk
shell. For this it introduces to the kiosk shell the concept of a "surface
tree": a list of kiosk shell surface structures having a common ancestor (in
the xdg protocol sense).

The design is based on the following assumptions that the kiosk shell currently
makes:

- A kiosk surface with no parent must be fullscreen.
- If a parent is set on a kiosk surface, that surface is assigned the output of
  the root kiosk surface. This means that all kiosk surfaces in a surface tree
  will always have the same output.
- There is no possibility to minimize a kiosk surface.

With these in mind, the following design decisions were deemed convenient:

- For every output, at most one surface tree list will be active. This means
  that, for a given output, only views belonging to surfaces of the same
  surface tree will be in the normal layer. Moreover, all such views will be in
  the normal layer if the surface tree list is active.
- The z-order of surface trees (the weston views' relative placement in the
  normal layer) is determined by the placement of their corresponding kiosk
  surface in the surface tree list.

Each kiosk shell surface begins its life as root of its own surface tree list.
Whenever a parent is set on a surface, that surface is linked to the surface
tree list of the root surface of the parent. If a parent kiosk shell surface is
destroyed, its children will keep the link to the root surface's surface tree
list. If the destroyed parent is also the root surface of the surface tree,
each child is unlinked from this root and they become the root of a new surface
tree.

This commit introduces to the kiosk_shell_surface structure the fields
'surface_tree_list', representing the surface tree list to which the surface is
linked at creation as its root, and 'surface_tree_link', the link to the
surface tree list.

6cb2526b67 Move shell-utils to its own directory
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).

This commit contains no functional changes to any observable code.
