Reviewed by Darin.

Make MathExtras.h thread safe.

• kjs/math_object.cpp: (KJS::mathProtoFuncRandom): If threading is enabled, rely on initializeThreading to call wtf_random_init().

• wtf/Threading.h:
• wtf/ThreadingGtk.cpp: (WTF::initializeThreading):
• wtf/ThreadingNone.cpp: (WTF::initializeThreading):
• wtf/ThreadingPthreads.cpp: (WTF::initializeThreading):
• wtf/ThreadingWin.cpp: (WTF::initializeThreading): Call wtf_random_init(); made the function non-inline to avoid having to include too many headers in Threading.h.
