This fixes the omissions of configparser, copyreg, queue and
socketserver renaming.

Added stub module for repr.

If configparser is unavailable, try to import configparser using its
old name. This is required for backward-compatibility with older
Python versions.

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)
