Summary: remove bad INCREF, propagate exception

Initial Comment:
This is my very first foray into the Python
interpreter, so please be patient.  It looks like to me
that this INCREF is wrong since the PyList_Append()
will steal the reference.  Also I tested it.  Current
CVS does this:

>>> import gc
>>> len(gc.get_objects())
1559
>>> len(gc.get_objects())
1562
>>> len(gc.get_objects())
1565
>>> len(gc.get_objects())
1568
>>> len(gc.get_objects())
1571
>>> len(gc.get_objects())
1574

and with my patch it does this:

>>> import gc
>>> len(gc.get_objects())
1559
>>> len(gc.get_objects())
1559
>>> len(gc.get_objects())
1559
>>> len(gc.get_objects())
1559
>>> len(gc.get_objects())
1559
>>> len(gc.get_objects())
1559
>>> len(gc.get_objects())
1559


In addition I added checks for error return from
PyList_Append(), and propagated the exception condition
up the callstack.

Oh, and here is a new version of the patch, which also tests
for failure from PyList_New().
