    Returns a normalized, absolute version of the final path.

    The final path must be located inside of the base path component (otherwise
    a ValueError is raised).

    On Windows, some files are read-only (e.g. in in .svn dirs), so when
    rmtree() tries to remove them, an exception is thrown.
    We catch that here, remove the read-only attribute, and hopefully
    continue without problems.
