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.

d21563360a shell: Move weston_curtain_create params into the struct
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.

3a298b0b05 shell: Rename weston_solid_color_surface to weston_curtain_params
The name implied that it was a surface in and of itself, rather than

f3221832c5 kiosk-shell: Favor out views on same output
In multiple output cases, finding the succesor from the inactive layer
might result in picking the wrong view when there are multiple views
being stacked in the inactive layer. This adds two additional checks to

f3ad593925 kiosk-shell: Don't occlude shsurf on other outputs
This adds an additional check to make sure the current focus surface
is on the same output as the surface that is going to be activated.

This is necessary in order to avoid placing the currently focused one in
the inactive layer, which shouldn't happen in situations where the new
surface is going to be placed on a different output than the currently
focused one.

8a1849db8a kiosk-shell: Check if app_ids have been set after initial commit
Some applications would set-up the app_id after the initial commit
(without a buffer) which is too late to correctly assign the application
to the corresponding output set-up in the configuration file.

This patch fixes that by checking one more time, after a buffer has been
attached, if indeed there's an output with an app_id set.

Fixes: #469

f676a8f54e kiosk-shell: Add a border fill to non-fullscreen views
According to xdg-shell spec, if the surface doesn't cover the whole
output we should center it and install a border fill covering the rest
of the output.

While we center out the surface we never got around installing the
border fill. This patch re-uses the activation of a surface to control
this bit as well, by making use of an new layer to place the
surface while not being active.

79cf52e556 kiosk-shell: Handle child top-level windows at destruction
With the seperation of surface activation and keyboard input, a special
corner case arose for child top-level windows when surfaces are being
destroyed. To make sure we never pick the wrong window to activate upon
destruction, we verify if the current focused surface is different than
the one being destroyed.

365f445eab kiosk-shell: Embed keyboard focus activation code
Just like desktop-shell, we shouldn't be dependent on having a keyboard
be present in order to activate a window/surface.

This adds a libweston helper to retrieve the first available seat, and
to use it in order to avoid going over the seat list.

We also encapsulate the activation of the surface in one place, and use
it on surface removal, when the surface has been committed, or for
touch/pointer events. With it we also deal with the keyboard focus and
shell activation in one place.

092130c4bf kiosk-shell: Keep track of seats created and destroy them at end
kiosk_shell_destroy() will free up weston_desktop, but still keeping
listeners set-up (keyboard/seat/caps), which will fire
when the the compositor is stopped/shutdown by clients still connected.

This patch maintains a list of seats and uses it to remove any listeners
when calling kiosk_shell_destroy(). desktop-shell and ivi-shell do not
appear to be using weston_desktop_destroy() in their respective destroy
parts.

This avoids an illegal access happening when calling one of the
listeners, after weston_desktop has been free'ed, like the following:

87c1679a0a kiosk-shell: Introduce kiosk/fullscreen shell for desktop apps
kiosk-shell is fullscreen shell for apps that use the xdg-shell
protocol. The goal is to make life easier for people shipping embedded
devices with simple fullscreen shell requirements, and reduce the
proliferation of desktop-shell hacks.

Top level surfaces are made fullscreen, whereas dialogs are placed on
top in the center of the output and retain their natural sizes. Dialogs
can be moved and (un)maximized, but resizing is currently not supported.

An app can be directed to a particular output by populating the
"app-ids" field with the app's XDG app id, in the relevant
"[output]" section in the weston config file.

Fixes: #277
