Auto merge of #43046 - milmazz:bootstrap-unittest, r=aidanhs
bootstrap: Add doctests and unitests This commit includes the following changes: * Include more docstrings in classes, methods, and functions * Add doctests, which are great for self-documenting our source code * Add some unit tests with the `unittest` module * Remove `WindowsError` reference on non-windows systems * Rename some variables to be more explicit about their meaning * Move all the attributes defined outside of `__init__` * Add initial support for Python 3 r? @alexcrichton
