  BUG: ticket #2063, make unique return consistent index.

Make unique use  mergesort when return_index is true. This quarantees that
the returned indices are of the first occurrence of the unique elements and
makes the behavior better defined and consistent.

  BUG: Ticket #1672 fix allclose to work for scalar inf.

Backport of 7497d60.

Also actually runs tests. Tests were not run before because the allclose
test class was a subclass of TestCase and used generators. This is not
supported by nose, tests will be skipped.

Also changes plain asserts to assert_().

Thanks to Justin Peel for the allclose inf fix.

  BUG: ticket #2017, fix type hash.

This is a squashed backport of 4 commits.
STY: cleanup hashdesc.c to follow our C conventions.

BUG: fix inconsistencies in dtype flag type at the C level.

Conflicts:

	numpy/core/src/multiarray/descriptor.c
	numpy/core/src/multiarray/hashdescr.c

BUG: fix #2017 by ignoring type_num in the hash input.

Since type_num is not considered in PyArray_EquivTypes (for dtype
equality comparison), seems reasonable to ignore it for hashing as
well.

Conflicts:

	numpy/core/tests/test_dtype.py

BUG: fix flags type when exposed to python.

  BUG: ticket #2021. Fix segfault.

The return from PyArray_DescrFromObject PyArray_SearchSorted needed
to be checked for NULL. Also added checks in other spots where
PyArray_DescrFromObject was called. Added regression test for same.
Made a few small code cleanups along the way.

All the checks may not be necessary, but
1) No one should have to waste brain cycles figuring that out.
2) Bugs happen.
3) Things change.
