backport gvanrossum's patch:

SF bug #543387.

Complex numbers implement divmod() and //, neither of which makes one
lick of sense.  Unfortunately this is documented, so I'm adding a
deprecation warning now, so we can delete this silliness, oh, around
2005 or so.

Bugfix candidate (At least for 2.2.2, I think.)
