Forward-port of r52136: a review of overflow-detecting code.
...
* unified the way intobject, longobject and mystrtoul handle
values around -sys.maxint-1.
* in general, trying to entierely avoid overflows in any computation
involving signed ints or longs is extremely involved. Fixed a few
simple cases where a compiler might be too clever (but that's all
guesswork).
* more overflow checks against bad data in marshal.c.
* 2.5 specific: fixed a number of places that were still confusing int
and Py_ssize_t. Some of them could potentially have caused
"real-world" breakage.
* list.pop(x): fixing overflow issues on x was messy. I just reverted
to PyArg_ParseTuple("n"), which does the right thing. (An obscure
test was trying to give a Decimal to list.pop()... doesn't make
sense any more IMHO)
* trying to write a few tests...

Fix a couple of bugs exposed by the new __index__ code. The 64-bit buildbots
...
were failing due to inappropriate clipping of numbers larger than 2**31
with new-style classes. (typeobject.c) In reviewing the code for classic
classes, there were 2 problems. Any negative value return could be returned.
Always return -1 if there was an error. Also make the checks similar
with the new-style classes. I believe this is correct for 32 and 64 bit
boxes, including Windows64.
Add a test of classic classes too.

I modified this patch some by fixing style, some error checking, and adding

I'm checking in now to get the greatest possible review and establish a
baseline for moving forward. I don't want this to hold up release if possible.

Remove "non-mapping" and "non-sequence" from TypeErrors raised by

PyMapping_Size and PySequence_Size.
Because len() tries first sequence, then mapping size, it will always
raise a "non-mapping object has no len" error which is confusing.
