py-packaging: updated to 20.4

20.4:

Canonicalize version before comparing specifiers.
Change type hint for canonicalize_name to return packaging.utils.NormalizedName. \ 
This enables the use of static typing tools (like mypy) to detect mixing of \ 
normalized and un-normalized names.

20.3:

Fix changelog for 20.2.

20.2:

Fix a bug that caused a 32-bit OS that runs on a 64-bit ARM CPU (e.g. ARM-v8, \ 
aarch64), to report the wrong bitness.

20.1:

Fix a bug caused by reuse of an exhausted iterator.

20.0:

Add type hints
Add proper trove classifiers for PyPy support
Scale back depending on ctypes for manylinux support detection
Use sys.implementation.name where appropriate for packaging.tags
Expand upon the API provded by packaging.tags: interpreter_name(), \ 
mac_platforms(), compatible_tags(), cpython_tags(), generic_tags()
Officially support Python 3.8
Add major, minor, and micro aliases to packaging.version.Version
Properly mark packaging has being fully typed by adding a py.typed file

* Add manylinux2014 support
* Improve ABI detection
* Properly handle debug wheels for Python 3.8
* Improve detection of debug builds on Windows

Log message:
py-packaging: add full py-attrs dependency, this is needed at runtime.

Fixes py-sphinx related build failures in other packages.

Bump PKGREVISION.

XXX: 'make test' needs 'make install' beforehand, please fix if you know how

Log message:
py-packaging: updated to 19.1

19.1:
* Add the packaging.tags module.
* Correctly handle two-digit versions in python_version

Log message:
py-packaging: updated to 19.0

19.0:

* Fix string representation of PEP 508 direct URL requirements with markers.

* Better handling of file URLs

  This allows for using file:///absolute/path, which was previously
  prevented due to the missing netloc.

  This allows for all file URLs that urlunparse turns back into the
  original URL to be valid.

Log message:
py-packaging: updated to 18.0

18.0:
Improve error messages when invalid requirements are given.
