py-setuptools: update to 47.3.2.

v47.3.2
-------

* #2071: Replaced references to the deprecated imp package with references to importlib

v47.3.1
-------

* #1973: Removed ``pkg_resources.py31compat.makedirs`` in favor of the stdlib. Use ``os.makedirs()`` instead.
* #2198: Restore ``__requires__`` directive in easy-install wrapper scripts.

v47.3.0
-------

* #2197: Console script wrapper for editable installs now has a unified template and honors importlib_metadata if present for faster script execution on older Pythons.
* #2195: Fix broken entry points generated by easy-install (pip editable installs).

v47.2.0
-------

* #2194: Editable-installed entry points now load significantly faster on Python versions 3.8+.

v47.1.1
-------

* #2156: Update mailing list pointer in developer docs

Incorporate changes from v44.1.1:

* #2158: Avoid loading working set during ``Distribution.finalize_options`` prior to invoking ``_install_setup_requires``, broken since v42.0.0.

v44.1.1
-------

* #2158: Avoid loading working set during ``Distribution.finalize_options`` prior to invoking ``_install_setup_requires``, broken since v42.0.0.

v47.1.0
-------

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

v47.0.0
-------

* #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.

v46.4.0
-------

* #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.

v46.3.1
-------

No significant changes.

v46.3.0
-------

* #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``.

v46.2.0
-------

* #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>`_.

v46.1.3
-------

No significant changes.

v46.1.2
-------

* #1458: Added template for reporting Python 2 incompatibilities.

v46.1.1
-------

No significant changes.

v46.1.0
-------

* #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``.

Incorporate changes from v44.1.0:

* #1704: Set sys.argv[0] in setup script run by build_meta.__legacy__
* #1959: Fix for Python 4: replace unsafe six.PY3 with six.PY2
* #1994: Fixed a bug in the "setuptools.finalize_distribution_options" hook that lead to ignoring the order attribute of entry points managed by this hook.

v44.1.0
-------

* #1704: Set sys.argv[0] in setup script run by build_meta.__legacy__
* #1959: Fix for Python 4: replace unsafe six.PY3 with six.PY2
* #1994: Fixed a bug in the "setuptools.finalize_distribution_options" hook that lead to ignoring the order attribute of entry points managed by this hook.

v46.0.0
-------

* #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.

v45.3.0
-------

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

v45.2.0
-------

* #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.

v45.1.0
-------

* #1458: Add minimum sunset date and preamble to Python 2 warning.
* #1704: Set sys.argv[0] in setup script run by build_meta.__legacy__
* #1974: Add Python 3 Only Trove Classifier and remove universal wheel declaration for more complete transition from Python 2.

v45.0.0
-------

* #1458: Drop support for Python 2. Setuptools now requires Python 3.5 or later. Install setuptools using pip >=9 or pin to Setuptools <45 to maintain 2.7 support.
* #1959: Fix for Python 4: replace unsafe six.PY3 with six.PY2
