[issue9018] os.path.normcase(None) does not raise an error on linux and should

[R. David Murray]

New submission from R. David Murray <rdmurray at bitdance.com>:

os.path.normcase(None) raises an error on Windows but returns None on linux.  os.path.abspath(None) raises an error in both cases.  os.path.normcase(None) should raise an error on linux.

I've only marked this for 3.2 because I suspect there may be linux code out there that this will break, so the fix should probably only be applied to 3.2.  (I discovered this because a unit test someone else wrote passed on linux but failed on windows.)
