[Distutils] Setuptools should not depend on setuptools.

[Lennart Regebro]

When porting setuptools to Python 3, I recently looked into doing the
3.0 development a bit nicer, by being able to run 2to3 as a part of
the installation or test commands. However, this turns out to be
impossible, because every part of setuptools assumes that setuptools
is available and working. This also means, even under Python 2.x
development, that should you break for example the dist module a bit
too much, setuptools stops working, and you can't even run the tests.

Therefore, one thing that should be done is to make setuptools not
depend on setuptools. Building, installoing, testing, should require
disutils only.

I'm not going to work on this, at least not until after the summit.
