[pyup-bot]

This PR updates setuptools from 40.3.0 to 40.6.2.

Changelog

40.6.2

-------

* 1592: Fix invalid dependency on external six module (instead of vendored version).

40.6.1

-------

* 1590: Fixed regression where packages without ``author`` or ``author_email`` fields generated malformed package metadata.

40.6.0

-------

* 1541: Officially deprecated the ``requires`` parameter in ``setup()``.
* 1519: In ``pkg_resources.normalize_path``, additional path normalization is now performed to ensure path values to a directory is always the same, preventing false positives when checking scripts have a consistent prefix to set up on Windows.
* 1545: Changed the warning class of all deprecation warnings; deprecation warning classes are no longer derived from ``DeprecationWarning`` and are thus visible by default.
* 1554: ``build_meta.build_sdist`` now includes ``setup.py`` in source distributions by default.
* 1576: Started monkey-patching ``get_metadata_version`` and ``read_pkg_file`` onto ``distutils.DistributionMetadata`` to retain the correct version on the ``PKG-INFO`` file in the (deprecated) ``upload`` command.
* 1533: Restricted the ``recursive-include setuptools/_vendor`` to contain only .py and .txt files.
* 1395: Changed Pyrex references to Cython in the documentation.
* 1456: Documented that the ``rpmbuild`` packages is required for the ``bdist_rpm`` command.
* 1537: Documented how to use ``setup.cfg`` for ``src/ layouts``
* 1539: Added minimum version column in ``setup.cfg`` metadata table.
* 1552: Fixed a minor typo in the python 2/3 compatibility documentation.
* 1553: Updated installation instructions to point to ``pip install`` instead of ``ez_setup.py``.
* 1560: Updated ``setuptools`` distribution documentation to remove some outdated information.
* 1564: Documented ``setup.cfg`` minimum version for version and project_urls.
* 1572: Added the ``concurrent.futures`` backport ``futures`` to the Python 2.7 test suite requirements.

40.5.0

-------

* 1335: In ``pkg_resources.normalize_path``, fix issue on Cygwin when cwd contains symlinks.
* 1502: Deprecated support for downloads from Subversion in package_index/easy_install.
* 1517: Dropped use of six.u in favor of `u""` literals.
* 1520: Added support for ``data_files`` in ``setup.cfg``.
* 1525: Fixed rendering of the deprecation warning in easy_install doc.

40.4.3

-------

* 1480: Bump vendored pyparsing in pkg_resources to 2.2.1.

40.4.2

-------

* 1497: Updated gitignore in repo.

40.4.1

-------

* 1480: Bump vendored pyparsing to 2.2.1.

40.4.0

-------

* 1481: Join the sdist ``--dist-dir`` and the ``build_meta`` sdist directory argument to point to the same target (meaning the build frontend no longer needs to clean manually the dist dir to avoid multiple sdist presence, and setuptools no longer needs to handle conflicts between the two).
