to a single #define instead of having several copies in several files.

This excludes the Modules/ tree (datetime and expat both have a copy
for their own purposes with no need for it to be the same).

This copy also had a bug in it, it fails to incorporate the length
into the hash by using it as the loop variable so it'll always be -1
by the time it is XORed in.

As such: I'm doing this only in Python 3.3 and not backporting as it
would change the existing hash behavior of datetime objects.
