'SHA1' instead of 'SHA'.
Add more tests for hashlib and hash object attributes

'SHA1' instead of 'SHA'.

With the exception of the 'as_string' call in the policy docs.
That one is a separate issue.

Note that when building the docs sphinx is complaining about
.. testcleanup:: being an invalid directive.  I don't know
why this is, as I'm following the sphinx docs...but fortunately
the action is to omit the text in the body, so the generated
documentation is correct.

With help from jkloth on IRC, so it will hopefully work
this time :)

Also including this change in 3.3 to help avoid spurious conflicts
between the two most active branches.

The former block size traded away good fit within cache lines in
order to gain faster division in deque_item().  However, compilers
are getting smarter and can now replace the slow division operation
with a fast integer multiply and right shift.  Accordingly, it makes
sense to go back to a size that lets blocks neatly fill entire
cache-lines.

GCC-4.8 and CLANG 4.0 both compute "x // 62" with something
roughly equivalent to "x * 9520900167075897609 >> 69".

Patch from Phil Connell.

* handle _PyMem_RawStrdup() failure
* Py_FrozenMain() releases memory on error
* Py_FrozenMain() duplicates the old locale, as done in main()
