This change is in line with the project's rebranding.

The collection is also changed a bit to drop the "meta-" prefix. There
is no clear standardization on the collection name. Some use an ID, some
use ID-layer, some use meta-ID etc. We have decided to use the the layer
name without the "meta-" prefix  because this is an ID, not a layer per
se.

WESTON_INI_BACKGROUND_COLOR - Background color - default to white.
WESTON_INI_BACKGROUND_TYPE  - Background type - defaults to centered.

Using systemd notify, a service dependency would be more robust. This
allows, for example, another service to depend on weston-init without
having to hack a sleep (or similar).

This creates a mechanism to generate a dynamic weston.ini configuration
based on build variables.

The entire mechanism is enabled using the WESTON_DYNAMIC_INI variable
(enabled when set to 1).

The default path for the weston.ini configuration is set in
WESTON_INI_PATH as "etc/xdg/weston/weston.ini".

WESTON_INI_NO_TOOLBAR, when set to 1, disables the weston toolbar.
