        Make MathExtras.h compatible with <cmath>
        https://bugs.webkit.org/show_bug.cgi?id=34618

        * wtf/MathExtras.h: Include <cmath> instead of <math.h>.
        Use "using" as we do elsewhere in WTF for the four functions from <cmath>
        we want to use without the prefix. Later we could consider making the std
        explicit at call sites instead.
