Forward-port of r52136,52138: 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...

-----------------
-- Integer negation and absolute value were fixed to not rely
- on undefined behaviour of the C compiler anymore.
+- list.pop(x) accepts any object x following the __index__ protocol.
+
+- Fix some leftovers from the conversion from int to Py_ssize_t
+ (relevant to strings and sequences of more than 2**31 items).

- Bug #1566800: make sure that EnvironmentError can be called with any
number of arguments, as was the case in Python 2.4.
