Improve the implementation of itertools.product()
...
* Fix-up issues pointed-out by Neal Norwitz.
* Add extensive comments.
* The lz->result variable is now a tuple instead of a list.
* Use fast macro getitem/setitem calls so most code is in-line.
* Re-use the result tuple if available (modify in-place instead of copy).
