    [TRAFODION - 2345] Support LOG() function of any base

    Like Oracle does, the function LOG() function supports 2 parameter of call, in this way,
the 1st parameter is the radix, and the second one is power, the function returns the logarithm.
    This change implement this, and still, the user can call it with only one parameter (form
LOG(X)), in which case the parameter X will be the power, and the function just returns the
natural logarithm of X. This is also compatible with MySQL.
