[issue1383] Backport abcoll to 2.6

[Guido van Rossum]

Guido van Rossum added the comment:

I've submitted this as revision 59106.  Thanks so much for your effort!

I cleaned up the layout of some of the files, and I had to undo a
diffing mistake -- somehow your patch undid some changes to
collections.py and test_collections.py about renaming NamedTuple to
namedtuple that were submitted by Raymond Hettinger.
