[issue2775] Implement PEP 3108

[Brett Cannon]

Brett Cannon <brett at python.org> added the comment:

Because of pickle compatibility in 2.x, all renames in the trunk need to 
be reverted. Work in 3.0 is still fine and won't be touched.

I have already updated the PEP with the new steps required for renames.
