setup: properly package distutils in py2exe virtualenv builds Our in-repo py2exe packaging code uses virtualenvs for managing dependencies. An advantage of this is that packaging is more deterministic and reproducible. Without virtualenvs, we need to install packages in the system Python install. Packages installed by other consumers of the system Python could leak into the Mercurial package. A regression from this change was that py2exe packages contained the virtualenv's hacked distutils modules instead of the original distutils modules. (virtualenv installs a hacked distutils module because distutils uses relative path lookups that fail when running from a virtualenv.) This commit introduces a workaround so py2exe packaging uses the original distutils modules when running from a virtualenv. With this change, `import distutils` no longer fails from py2exe builds produced from a virtualenv. This fixes the regression. Furthermore, we now include all distutils modules. Before, py2exe's module finding would only find modules there were explicitly referenced in code. So, we now package a complete copy of distutils instead of a partial one. This is even better than before. # no-check-commit foo_bar function name
