Initial patch by Daniel Urban and Aaron Iles

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()
