  TST: Added unit tests for assert_array_less

Added tests for simple arrays/elements,
tests that ensure that nans are not compared when they are in the same
position in both arrays but raise AssertionError when they are not,
and tests that ensure inf logic
(-np.inf < np.inf, 1.0 < np.inf, -np.inf < 1.0)
and that all other cases fail.

  Log Message:
  -----------
  TST: Added test that np.inf is not approx. -np.inf

This failed to raise AssertionError in an earlier rewrite of
assert_array_compare and is thus tested explicitly now.

  BUG: corrected behavior for assert_array_less

See issue #2418

assert_array_less does now treat inf/nan
correctly, namely:
-inf < x < inf for any real number x
nans still are not compared, when they occur
at the same position

To achieve this without breaking any other
functions relying on assert_array_compare,
an additional parameter (equal_inf) was
introduced that defaults to the old behavior
(analogous to equal_nan).

  DOC: Added changed behavior of assert_array_less

The bug that +/- inf where not treated correctly in
np.testing.assert_array_less changed the behavior and is thus mentioned
in the release notes.
