This change is one logical update to update the Wayland support. This
comprises of the following parts:
* Binding to both the shell and compositor global objects - necessary since
the API for setting top level status moved to the wl_shell interface
* The Wayland visual API went away and instead you setup the EGL surface
appropriately
* The message handling was refined to reflect the current behaviour - now
obsolete comments were removed and new comments updated
