            [BREWMP] Port WTF's randomNumber
            https://bugs.webkit.org/show_bug.cgi?id=33566
    
            Use GETRAND to generate 4 byte random byte sequence to implement
            weakRandomNumber. Create a secure random number generator with
            AEECLSID_RANDOM to implement randomNumber.
