This patch adds a new zipiterobject type to
iterobject.c so that we do not import itertools.izip to
do our iterative zip.

There is test_zip.py added that is a stripped down
version of the itertools test.

It's my first patch so go easy on me. ;)

I get a fatal error on the DECREF(ro) call at line 419 of
iterobject.c.  Investigating...

Deleting that line (line 419) fixes the problem.  Then all
tests pass.  The patch has small style issues though, and
I'm not sure whether the zip iter ought to have a
__length_hint__ method at all.

Removed the __length_hint__ stuff which clears up the
uninitialized ro which caused the seg fault.
Changed zip_create_iter to _PyZip_Create.
Added result into zipiter_traverse and zipiter_dealloc.

I've made some small changes and checked it in (r51620):

- fixed a few odd whitespace cases, e.g.
    for(i=0 ;
  into
    for (i = 0;

- disabled the specific type error

- rearranged the code so the type object is last;
  this reduces the number of forward decls needed

- shortened a long line
