REL: Update the 1.10 release notes.

Mention that diag and diagonal functions now preserve subtypes. That
can lead to incompatibilies with previous code using matrices.

DOC: Fixed incorrect assert_array_almost_equal_nulp documentation

The `max()` function previously used does not work with two array-like.
`maximum()` does, and is what is essentially used in the code
(`ref = nulp * np.spacing(np.where(ax > ay, ax, ay))`).

ENH: Add support for ATLAS > 3.9.33.

Recent ATLAS combines the previous libraries into two

* libsatlas -- single threaded.
* libtatlas -- threaded.

This fix is a bit of hack in that ATLAS > 3.9.33 is treated as a new,
separate library covered by atlas_3_10_info, but the latter derived
from atlas_info, which treats the cblas, atlas, and atlas_lapack
libraries separately, so the new info has a bit of repetition.

The alternative would be to rewrite atlas_info, but that can wait
on a larger cleanup of the build system.

Closes #3774.
BUG: Xerbla doesn't get linked in 1.10-devel.

Add our python_xerbla to the multiarray sources. That function is
needed for all modules that link to the ATLAS 3.10 libraries, which
are now all located in two files, libsatlas and libtatlas.

Also make the test for xerbla linkage work better. If xerbla is not
linked the test will be skipped with a message.

Closes #5362.
