I proposed removing QGtkStyle altogether, but moving it to qtstyleplugins is
also a good idea. We just need to make sure we don't load it when the platform
theme is gtk3 (as one can't load gtk2 and gtk3 libraries at the same time).

Do we really need to keep gtk2 support in qtbase? I.e., do we really need to
keep gtk2 theme if we have gtk3 theme?

Also the latter patch will need some rebasing for new version and new
copyrights.
