Creates a new GValue which represents the str value given as argument. This is
the opposite of the function gda.data_handler.DataHandler.getStrFromValue. The type argument
is used to determine the real data type requested for the returned value.
If the str string is null, then the returned GValue is of type GDA_TYPE_NULL;
if the str string does not correspond to a valid string for the requested type, then
null is returned.
Note: the str string must be in the current locale representation
