Christoph Haag 7a1dbbe8a1 st/oxr: Ensure quaternion is normalized in xrLocateViews() 
In rare cases the state tracker's pose transformations resulted in a quaternion
that accumulated float precision errors such that the norm of the quaternion was
not within float precision of 1.0 anymore.

Introduce a function math_quat_ensure_normalized() that can be used after multiple
operations have been performed on a quaternion.
