Update setuptools to 47.1.0

[pyup-bot]

This PR updates setuptools from 45.1.0 to 47.1.0.

Changelog

47.1.0

-------

* 2070: In wheel-to-egg conversion, use simple pkg_resources-style namespace declaration for packages that declare namespace_packages.

47.0.0

-------

* 2094: Setuptools now actively crashes under Python 2. Python 3.5 or later is required. Users of Python 2 should use ``setuptools<45``.
* 1700: Document all supported keywords by migrating the ones from distutils.

46.4.0

-------

* 1753: ``attr:`` now extracts variables through rudimentary examination of the AST,
thereby supporting modules with third-party imports. If examining the AST
fails to find the variable, ``attr:`` falls back to the old behavior of
importing the module. Works on Python 3 only.

46.3.1

-------

No significant changes.

46.3.0

-------

* 2089: Package index functionality no longer attempts to remove an md5 fragment from the index URL. This functionality, added for distribute 163 is no longer relevant.
* 2041: Preserve file modes during pkg files copying, but clear read only flag for target afterwards.
* 2105: Filter ``2to3`` deprecation warnings from ``TestDevelop.test_2to3_user_mode``.

46.2.0

-------

* 2040: Deprecated the ``bdist_wininst`` command. Binary packages should be built as wheels instead.
* 2062: Change 'Mac OS X' to 'macOS' in code.
* 2075: Stop recognizing files ending with ``.dist-info`` as distribution metadata.
* 2086: Deprecate 'use_2to3' functionality. Packagers are encouraged to use single-source solutions or build tool chains to manage conversions outside of setuptools.
* 1698: Added documentation for ``build_meta`` (a bare minimum, not completed).
* 2082: Filter ``lib2to3`` ``PendingDeprecationWarning`` and ``DeprecationWarning`` in tests,
because ``lib2to3`` is `deprecated in Python 3.9 <https://bugs.python.org/issue40360>`_.

46.1.3

-------

No significant changes.

46.1.2

-------

* 1458: Added template for reporting Python 2 incompatibilities.

46.1.1

-------

No significant changes.

46.1.0

-------

* 308: Allow version number normalization to be bypassed by wrapping in a 'setuptools.sic()' call.
* 1424: Prevent keeping files mode for package_data build. It may break a build if user's package data has read only flag.
* 1431: In ``easy_install.check_site_dir``, ensure the installation directory exists.
* 1563: In ``pkg_resources`` prefer ``find_spec`` (PEP 451) to ``find_module``.

46.0.0

-------

* 65: Once again as in 3.0, removed the Features feature.
* 1890: Fix vendored dependencies so importing ``setuptools.extern.some_module`` gives the same object as ``setuptools._vendor.some_module``. This makes Metadata picklable again.
* 1899: Test suite now fails on warnings.
* 2011: Fix broken link to distutils docs on package_data
* 1991: Include pkg_resources test data in sdist, so tests can be executed from it.

45.3.0

-------

* 1557: Deprecated eggsecutable scripts and updated docs.
* 1904: Update msvc.py to use CPython 3.8.0 mechanism to find msvc 14+

45.2.0

-------

* 1905: Fixed defect in _imp, introduced in 41.6.0 when the 'tests' directory is not present.
* 1941: Improve editable installs with PEP 518 build isolation:

* The ``--user`` option is now always available. A warning is issued if the user site directory is not available.
* The error shown when the install directory is not in ``PYTHONPATH`` has been turned into a warning.
* 1981: Setuptools now declares its ``tests`` and ``docs`` dependencies in metadata (extras).
* 1985: Add support for installing scripts in environments where bdist_wininst is missing (i.e. Python 3.9).
* 1968: Add flake8-2020 to check for misuse of sys.version or sys.version_info.
