Use C++ <cmath> instead of <math.h>
Including math.h can pollute the default namespace, and break
some compilers if cmath versions of the method are declared as using.
Switching to C++ math functions also greatly simplifies handling of
float qreal as C++ automatically chooses the right method.
[ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any
sources depending on that indirect inclusion may fail to build.
