[stdlib-sig] Making the reorg work

[Raymond Hettinger]

> So, the following the workflow?
> 1. svn mv Lib/BadOldName.py Lib/badoldname.py (in trunk)
> 2. Fix imports in the stdlib and update the docs.
> 3. Commit and merge into 3.0.
> 4. (back in trunk) make a file that does a start import (modules with
> __all__ will require some more work) in lib-old and gives a py3k
> warning
> 5. Block that revision

6. Make a 2-to-3 converter
