Dropping support for Python 2.4 and 2.5 / supporting Python 3

[Gregory Szorc]

lib2to3 is really just a generic source code rewriting facility. We could
do things like introduce b'' literals and use 2to3 to remove them so things
would work on 2.4 and 2.5.

But I still contend Python 3 support will be much easier without having to
consider 2.4 and 2.5.
