 replace deprecated np.asscalar with ndarray.item

`np.asscalar` was deprecated in Numpy 1.16. Since the unit tests
treat deprecation warnings as errors, we have to fix this in order
for the unit tests to pass with Numpy >= 1.16.

 specify 64-bit integer literals portably

On a 32-bit architecture, the expression `4L` is not a 64-bit
literal. On the other hand, `(int64_t)4` is.

This fixes unit test errors on 32-bit architectures (armhf).
