Add minimize feature to QWindow using wayland's xdg-shell

The feature is disabled by default,
and can be enabled at runtime
by exporting QT_WAYLAND_USE_XDG_SHELL env variable.

This patch relies on presence of protocol file
which has been imported from weston-1.4.0 sources,
until the xdg-shell is merge into wayland itself.

Because xdg-shell is experimental,
code fallback to WaylandShell if no XdgShell
but keep in mind those shells are exclusive.

Since xdg-shell and wayland-shell share most of the API,
some factorization is done by an (empty) abstraction class
to keep the code more readable.

Despite xdg-shell introduces new popups concept,
they're not used on this change for maitainance purpose.

Notes:

* This change depends on presence of xdg-shell protocol file.

* You can check a demo video
  (qt-tizen-cinematic-experience-20140430-rzr)
  of the test case at :
  https://www.youtube.com/watch?v=pY_XXvKc_0E#

* Use Super+Tab to show window again if hidden
