Raymond Hettinger 73d7963242 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).

Jack Diederich 36234e8f66 * regression bug, count_next was coercing a Py_ssize_t to an unsigned Py_size_t 
which breaks negative counts
* added test for negative numbers
will backport to 2.5.1

Neal Norwitz 69e8897505 Bug #1550714: fix SystemError from itertools.tee on negative value for n.

Armin Rigo a3f092751a ("Forward-port" of r46506) 
Remove various dependencies on dictionary order in the standard library
tests, and one (clearly an oversight, potentially critical) in the
standard library itself - base64.py.

Remaining open issues:
 * test_extcall is an output test, messy to make robust
 * tarfile.py has a potential bug here, but I'm not familiar
   enough with this code.  Filed in as SF bug #1496501.
 * urllib2.HTTPPasswordMgr() returns a random result if there is more
   than one matching root path.  I'm asking python-dev for
   clarification...

Tim Peters beb7c0c434 test_sf_950057's gen1() used an assert statement, which caused the test 
to fail when running with -O.  Changed to raise AssertionError instead.
