This copy of `setup.py` is obsolete, as it builds the old C++ backend for Protobuf, which has been deprecated and
unused since 4.21.0 when
[the backend was switch to upb](https://protobuf.dev/news/2022-05-06/#python-updates).
The `setup.py` that we actually distribute in our source packages is located in [`python/dist/setup.py`](https://github.com/protocolbuffers/protobuf/blob/main/python/dist/setup.py). It is not possible to build this `setup.py` directly from the GitHub repo or GitHub release tarball, because it depends on the file layout of our Python source package ([as distributed on PyPI](https://pypi.org/project/protobuf/#files)). The Python source package uses a layout that pulls together all of the things Python needs:
|Python Source Package Path|GitHub Repo Path|Description|
|-----|-----|-----|
|`setup.py`|`python/dist/setup.py`|
|`google/protobuf/*`|`python/google/protobuf/*`|pure Python sources|
|`python/*`|`python/*`|C extension sources|
|`utf8_range/*`|`third_party/utf8_range`|C UTF-8 Validation Library|
|`upb/*`|`upb/upb/*`|C Protobuf Library|
Users who want to build their own Python packages should build from our source package on PyPI, not from our GitHub repo or our GitHub release tarball.
It is also possible to build our source package from GitHub using the following command (this requires Bazel):
```
$ bazel build //python/dist:source_wheel
```

This change moves almost everything in the `upb/` directory up one level, so
that for example `upb/upb/generated_code_support.h` becomes just
`upb/generated_code_support.h`. The only exceptions I made to this were that I
left `upb/cmake` and `upb/BUILD` where they are, mostly because that avoids
conflict with other files and the current locations seem reasonable for now.
The `python/` directory is a little bit of a challenge because we had to merge
the existing directory there with `upb/python/`. I made `upb/python/BUILD` into
the BUILD file for the merged directory, and it effectively loads the contents
of the other BUILD file via `python/build_targets.bzl`, but I plan to clean
this up soon.

A couple weeks ago we moved upb into the protobuf Git repo, and this change
continues the merger of the two repos by making them into a single Bazel repo.
This was mostly a matter of deleting upb's WORKSPACE file and fixing up a bunch
of references to reflect the new structure.
Most of the changes are pretty mechanical, but one thing that needed more
invasive changes was the Python script for generating CMakeLists.txt,
make_cmakelists.py. The WORKSPACE file it relied on no longer exists with this
change, so I updated it to hardcode the information it needed from that file.

* Bazelfying conformance tests
Adding infrastructure to "Bazelify" languages other than Java and C++
* Delete benchmarks for languages supported by other repositories
* Bazelfying benchmark tests
* Bazelfying python
Use upb's system python rule instead of branching tensorflow
* Bazelfying Ruby
* Bazelfying C#
* Bazelfying Objective-c
* Bazelfying Kokoro mac builds
* Bazelfying Kokoro linux builds
* Deleting all deprecated files from autotools cleanup
This boils down to Makefile.am and tests.sh and all of their remaining references
* Cleanup after PR reorganizing
- Enable 32 bit tests
- Move conformance tests back
- Use select statements to select alternate runtimes
- Add internal prefixes to proto library macros
* Updating READMEs to use bazel instead of autotools.
* Bazelfying Kokoro release builds
* First round of review fixes
* Second round of review fixes
* Third round of review fixes
* Filtering out conformance tests from Bazel on Windows (b/241484899)
* Add version metadata that was previously scraped from configure.ac
* fixing typo from previous fix
* Adding ruby version tests
* Bumping pinned upb version, and adding tests to python CI
* Drop Python versions <3.7.
* Updated README to clarify that Python 3.7 is the minimum.
* Removed more Python 3.5-specific code.
Also changed tests to skip missing interpreters.
* Invoke tox directly instead of through Python.
Hopefully this will pick up python3.
* Updated java_stretch image to bullseye to get Python >= 3.7.
* Use jdk11 instead of jdk8.
* Installed python2 for gtest.
* Use "python3 -m venv" instead of "virtualenv."
* Install python3-venv.
* Fix a typo
* Fix lots of spelling errors
* Fix a few more spelling mistakes
* s/parsable/parseable/
* Don't touch the third party files
* Cloneable is the preferred C# term
* Copyable is the preferred C++ term
* Revert "s/parsable/parseable/"
This reverts commit 534ecf7675.
* Revert unparseable->unparsable corrections
Fix indentation to enable code formatting for sample command lines to set them
visually apart from the surrounding text, and make it easy to copy-paste.
Add code formatting for env vars, paths, binary and library names for
readability.
Hide URLs behind text for readability and conciseness.
Reflect the change that protobuf should now only be supporting 2.6+ (I'd guess note python 3.x+ when its supported in implementation)
Refer to the Python Packaging User Guide for installing setuptools (and pip) instead of out of date telecommunity guide.
- Improved readmes.
- Fixed incorrect definition of kint32min.
- Fixed absolute output paths on Windows.
- Added info to Java POM that will be required when we upload the
package to a Maven repo.
