36fbb730a7 fix one visible and several possible refleaks in rangeobject.c 
In some cases, the code was just reordered to allow for less decrefing.

d550c9a281 Issue #7298: Fix a variety of problems leading to wrong results with 
the fast versions of range.__reversed__ and range iteration.  Also
fix wrong results and a refleak for PyLong version of range.__reversed__.

Thanks Eric Smith for reviewing, and for suggesting improved tests.

418f81d9b6 Issue #1766304: The range.__contains__ optimization should only be 
applied to ints, not to instances of subclasses of int.

3e124ae739 Issue #1766304: Optimize membership testing for ranges: 'n in range(...)' 
does an O(1) check, if n is an integer.  Non-integers aren't affected.
Thanks Robert Lehmann.

e94c679df0 Issue #1717: rename tp_compare to tp_reserved. I'll change the 
type of tp_compare in a separate commit, for ease of reversion
should things go wrong.

a22e8bdfd9 Added all PyTypeObjects to the appropriate header files. 
Before the patch a lot of internal types weren't available in the header files. The patch exposes the new iterators, views and some other types to all C modules. I've also renamed some of the types and tp_names.

f83be4e3f3 Added view and iterator types to collections / _abcoll 
I've also renamed several of the iterators to keep a consistent naming schema.

b7f17e4bb4 Found another memory leak in longrangeiter. And redo the previous correction 
without calling PyType_Ready().

Question 1: Should the interpreter register all types with PyType_Ready()?
Many types seem to avoid it.

Question 2: To reproduce the problem, run the following code:
    def f():
        while True:
           for a in iter(range(0,1,10**20)):
              pass
    f()
And watch the memory used by the process.
How do we test this in a unittest?
