The distutils module should continue to use the old ConfigParser name,
for backward-compatibility.

not appear to be a new bug, its just that the test coverage went up
recently exposing it.  (I verified that by testing this test code on
an older Modules/_bsddb.c)

As explained by Marc-Andre Lemburg, distutils needs to stay
backward-compatible. Therefore, it should use the old ConfigParser
module name.

Updated the documentation to use the new name.
Revert addition of the stub entry for the old name.

Georg, I am reverting your changes since this commit should propagate
to py3k.

Stub modules will be easier to track (and remove) if they are all kept
in lib-old/, instead of sprinkling them throughout the library.
