seeding RandomState with long fails

[Valentin Churavy]

The code

import numpy as np
np.random.RandomState(1l)

fails with the following error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/pypy/site-packages/numpy/random/mtrand.py", line 451, in __init__
    self.seed(seed)
  File "/opt/pypy/site-packages/numpy/random/mtrand.py", line 485, in seed
    init_by_array(self.internal_state, obj, obj.shape[0])
NameError: global name 'init_by_array' is not defined

It would be nice if I could seed the random generator with longs or alternatively if the error message could be a bit clearer.

fixed in changeset f58d51c, both init_by_array() and long seeds should now work
