[Python-Dev] creating __all__ in extension modules

I thought I answered this question already when Fredrik asked it.  In os.py,
to build its __all__ list based upon the myriad different sets of symbols it
might have after it's fancy footwork importing from various os-dependent
modules, I think it's easiest to rely on those modules telling os what it
should export.
