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.

This will allow us to create a solid weston_buffer as well, since we
need to store that separately.

Not all solid-colour views want to be opaque: sometimes we use them with
non-opaque alpha values in order to shade views underneath them.

Given that we have a struct for argument params, we might as well use it
rather than have them split between the struct and native params. For
consistency between the implementations, this also includes a shift from
float to int positioning for the base offset within the compositor's
global co-ordinate space.

The name implied that it was a surface in and of itself, rather than
parameters used by a helper to create a surface and view.
Rename it now that we have weston_curtain as a name, and clean up
initialisers.

create_solid_color_surface actually returns a weston_view that it
creates internally. Since weston_solid_color_view is long and dull,
rename it to weston_curtain.

This simulates an output removal which should trigger a crash when
the compositor is shutdown abruptly by having a view with a listener installed
on its output_destroy signal.
This patch assumes that weston_compositor_remove_output() has already
been amended to use the more safer version for triggering signal
emission.
As both shells use this construct it should catch any potential signal
corruption.
