PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable

Removed calls to PyFloat_AsReprString.
...
This is in anticipation of possibly implementing issue 7117 (short float repr).
This removes the last calls to PyFloat_AsString, PyFloat_AsReprString, and
PyFloat_AsStringEx, which are unsafe.
Also, switch to defines for error values to bring this code more in line
with the py3k branch.

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...

This code is actually not used unless WITHOUT_COMPLEX is defined.

However, there was no error checking that PyFloat_FromDouble returned
a valid pointer. I believe this change is correct as it seemed
to follow other code in the area.

[ 1180995 ] binary formats for marshalling floats
Adds 2 new type codes for marshal (binary floats and binary complexes), a
new marshal version (2), updates MAGIC and fiddles the de-serializing of
code objects to be less likely to clobber the real reason for failing if
it fails.
