Implement initial IVI-shell support with shell integration.
IVI-shell provides a shell interface for Weston, which maps the GENIVI
API (http://www.genivi.org) for In-Vehicle Infotainment as Wayland-Ivi-Extension
(http://wiki.projects.genivi.org/index.php/Wayland_IVI_Extension_Design).
This patch is included in two protocol. The first is ivi-application protocol
which provided by weston. Next is ivi-controller protocol which provided by
Genivi's wayland-ivi-extension.
In IVI use case, the client create and destroy surface with the unique ID
by using ivi-application protocol. On the other hand, the controller such as
HMI Controller control some properties, which are visibility, position, size,
etc, with created the unique ID by using ivi-controller protocol.
It means the unique ID is necessary to create and control the ivi-surface and
the the ivi-layer. However Qt has no API to set the some surface or layer ID.
In this ivi-shell plugin, the unique ID can be set via the environment
parameter so that we can control the ivi-surface and ivi-layer. The
name of environment parameter is QT_IVI_SURFACE_ID.
QT_IVI_SURFACE_ID will be used as ivi-surface and ivi-layer. If application
needs more than two surfaces, ivi-surface IDs will be incremented.
When QT_IVI_SURFACE_ID isn't set, ivi-surface and ivi-layer ID will be
generated internally. The ID consists of the process ID and the surface
ID which is incremented in ivi-shell plugin.
The process ID is used as lower 22 bit per 32bit. 23 to 32 bit is used as
the surface IDs in a process.
e.g. When the process ID is 0x765 and create two surfaces,
ivi-layer ID is 0x765 and ivi-surface IDs are 0x765 and 0x00400765.

We can set QT_WAYLAND_SHELL_INTEGRATION of the environment
parameter to "ivi-shell" to use IVI-shell.
