Bug 1178: Implement X11UnderlayTracker

driver/x11/X11UnderlayTracker
Using NEWT to initialize an X11 window for use by Raspberry Pi users
to handle mouse and keyboard input when using the bcm.vc.iv driver inside xorg.

newt/driver/bcm/vc/iv/WindowDriver
Try use X11UnderlayTracker as input for bcm.vc.iv
If X11 fail to initialize then
track using the /dev/event files directly
using the LinuxMouseTracker.

Input source is switched inside bcm/vc/iv/WindowDriver
by using the new
newt/driver/KeyTracker
newt/driver/MouseTracker
interfaces.

Bug 1178: X11UnderlayTracker Fix cc4. Attempted fix for cc6.

Rename window -> underlayWindow.
Fix indentation, long lines & whitespace.

Bug 1178 cc4: another window overlaps NEWT underlay window -> overlay window is still on top.
Fix 1178 cc4: we can request the NEWT underlay window to use always on top.

Bug 1178 cc6: if you render the overlay window transparent -> caps.setBackgroundOpaque(false);
then you will see that the underlay tracker window newer repaints -> looks a bit like a mess.
Attempted fix 1178 cc6: x11 underlay tracker window can be set transparent as well.
FIXME: The underlay tracker window is still filled with opaque garbage.
