SWIG Java bindings improvements

Much-improved Java bindings. Java arrays can now be passed to functions
that take void *, without any special treatment.

        }

            data[i] = i * 3;
        }

        retval = xtract.xtract_mean(data, len, null, mean);
        retval = xtract.xtract_variance(data, len, mean, variance);
