[Distutils] Setuptools for Python 3 patch.

[Lennart Regebro]

I have in issue 56 ( http://bugs.python.org/setuptools/issue56 ) added
a patch for setuptools, that enable it to be ported to Python 3. If
somebody would like to review the patches, I would be much obliged.
There are many choices I've done that could be done differently,
stylistically.

The porting itself is done with

/opt/python30/bin/2to3 -wn .
/opt/python30/bin/2to3 -dw /tmp/setuptools.LOCAL/setuptools/tests/api_tests.txt

but you currently need to patch 2to3 (with patches which I sent to
this list yesterday by mistake, sorry about that).

Also, I have not done patching to remove all 2to3 warnings. There are
many "foo = map(fun, bar)" calls in the code, and these get converted
by 2to3 to the ugly "foo = list(map(fun, bar))". Changing them all to
"foo = [fun(x) for in in bar]" would be the Python3-approved way of
doing it, but I only fixed the things that was needed to make the port
work.


I'm going to make a blogpost about the porting experience. I'd also
like to provide a source dist tgz for testing by others in that blog
post, of that's OK. If it's not OK, then tell me.
