Attributes GH PR #822: https://github.com/ArcticaProject/nx-libs/pull/822

With the removal of the Ipaq code there's no path anymore to open the
onscreen keyboard. Also nxkbd is not available and we do not have
tested that feature with any onscreen keyboard yet. So there's no
point in integrating that code.

Fixes ArcticaProject/nx-libs#405

Did we ever provide a binary?

This is a bit weird, I'd expect far more places where the compiler
could complain about Window vs Window64... But it does not.

This fixes problems with kwin and compiz when using the
switch-all-screens keystroke. The fullscreen would appear shortly and
then vanish again.

Fixes ArcticaProject/nx-libs#458

We can only free the xkbDevicePrivate because we do not know the
details of any other (possible) extension. So let's limit to that one
private for now and call the new xkbFreePrivates from dix (where such
a function is completely missing).
