Just like desktop-shell, we shouldn't be dependent on having a keyboard
to be present in order to activate a window/surface.

This ensures the layers are torn down properly.

desktop-shell's client is able to read-up from the config file, [shell]
section the background, but for kiosk-shell we don't actually have
client that does that, so instead allow the shell do that directly.
Seems to be a useful thing to have, as a default background color.

When using xwayland surfaces and multiple outputs we need to notify
xwayland surface that the surface position has changed, otherwise we're
going to end up with pop-ups being displayed on other outputs rather
than the one were the main surface resides.

Stolen from desktop-shell.

Doing it when the surface is being added would cause clients that
wait for frame callbacks to wait indefinitely as the surface being
activated is not yet, committed.

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:

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
