    Return the default base location for distlib caches. If the directory does
    not exist, it is created. Use the suffix provided for the base directory,
    and default to '.distlib' if it isn't provided.

    On Windows, if LOCALAPPDATA is defined in the environment, then it is
    assumed to be a directory, and will be the parent directory of the result.
    On POSIX, and on Windows if LOCALAPPDATA is not defined, the user's home
    directory - using os.expanduser('~') - will be the parent directory of
    the result.

    The result is just the directory '.distlib' in the parent directory as
    determined above, or with the name specified with ``suffix``.

        This is called to create a connection instance. Normally you'd
        pass a connection class to do_open, but it doesn't actually check for
        a class, and just expects a callable. As long as we behave just as a
        constructor would have, we should be OK. If it ever changes so that
        we *must* pass a class, we'll create an UnsafeHTTPSConnection class
        which just sets check_domain to False in the class definition, and
        choose which one to pass to do_open.
