[Stackless] Preparing Stackless Python 3.1a2

[Richard Tew]

Hi,

I've merged in the changes from the mainline branch up to the Python
3.1a2 tag.  Doing this now, as the 3.1 release process proceeds,
removes work needed later on.  There are bugs requiring debugging and
fixing, before we can do a Stackless 3.1a2 tag.

The Stackless unit tests have a crash bug which needs to be looked into.

There are six test failures in the Python unit tests.  Two of these
are in the original mainline Python py3k branch and can be ignored,
leaving four that are because of either bad merging on my part or just
requiring mainline code to be Stacklessified.

If anyone wants to get involved and take a crack at debugging and
fixing any of these, feel free to give it a shot.  Myself, or maybe
Kristjan, will fix them in due course otherwise.
