I have turned my branch into a clean patch for default: https://bitbucket.org/Merwok/distutils2/changeset/076b15559290

Notes:

- You can diff configure.py against build.py and install_dist.py from an earlier revision to see what code has been moved where.

- Two tests for install_dist still fail, but this could be only the tip of the iceberg.  We need more tests there.  Installation paths is a tricky business, and we have to make sure configure does not break anything.

- I have changed install to install_dist in the code, tests and docs, but only in the part of the docs I added for configure.  The rest of the file is inaccurate, but that’s outside the scope of this patch.

- Some to-do features: distribute the configure.cache file in the dist-info directory (requires adding a hook system to install_distinfo); add info about the compiler type; probably more.
