[classlib][luni] Upgrade java.lang.Math java.lang.StrictMath

Hi All:
There are some newly added methods of class 
java.lang.Math/java.lang.StrictMath in JDK 1.5(compared with JDK 1.4), 
but not implemented in Harmony.
They are

    * *method* java.lang.Math.expm1(double): missing in harmony
    * *method* java.lang.Math.hypot(double, double): missing in harmony
    * *method* java.lang.Math.log1p(double): missing in harmony
    * *method* java.lang.Math.signum(double): missing in harmony
    * *method* java.lang.Math.signum(float): missing in harmony
    * *method* java.lang.Math.ulp(double): missing in harmony
    * *method* java.lang.Math.ulp(float): missing in harmony
    * *method* java.lang.StrictMath.expm1(double): missing in harmony
    * *method* java.lang.StrictMath.hypot(double, double): missing in
      harmony
    * *method* java.lang.StrictMath.log10(double): missing in harmony
    * *method* java.lang.StrictMath.log1p(double): missing in harmony
    * *method* java.lang.StrictMath.signum(double): missing in harmony
    * *method* java.lang.StrictMath.signum(float): missing in harmony
    * *method* java.lang.StrictMath.ulp(double): missing in harmony
    * *method* java.lang.StrictMath.ulp(float): missing in harmony


I'd like to implement them if no one objects.

Best regards

Great! And I just notice that you have already put up HARMONY-1415, 
HARMONY-1399, HARMONY-1388 about these two classes.

They look good. :-)
