Integrate FreeType 2.3.9 into the donut tree.
This is done to get fixes for a few security-related issues. NOTE: the auto-hinter hasn't been changed to avoid modifying the rendering of characters. The 2.3.9 code contains minor fixes (not security-related) that could in theory do that (though extensive testing is needed to evaluate its real impact on Android).
