 FINITE(DoubleNotANumber) doesn't return 0 at IsValidOp::isValid.

 I had make patch for this problem.

 the fixed points are as follows.[[BR]]
 1) change DoubleNotANumber value from 1.7e-308 to
 numeric_limits<double>::quiet_NaN().[[BR]]
 1) change DoubleInfinity value from 1.7e+308 to
 numeric_limits<double>::infinity().[[BR]]
 2) add DoubleMax definition (use numeric_limits<double>::max()), because
 JTS Double.MAX_VALUE and Double.POSITIVE_INFINITY are same in GEOS (I
 think that this is a bug).[[BR]]
 3) add Coordinate::isNull for get equality of NaN value.[[BR]]

 I think that xnix environment have same problem (platform.h.in).
