isNull() would forward to the contained type and check that type's isNull() method for some of the builtin types. Remove that behavior and only return true in isNull(), if the variant is invalid, doesn't contain data or contains a null pointer. In addition, implement more consistent behavior when constructing a QVariant using the internal API taking a copy from a void *. isNull() should return true in both cases. This mainly changes behavior for some corner cases and when using our internal API. [ChangeLog][Important Behavior Changes] QVariant::isNull() no longer returns true when the variant contains an object of some type with an isNull() method, that returns true for the object; QVariant::isNull() now only returns true when the variant contains no object or a null pointer.
