Commit Message

Merge pull request #2891 from misl6/release-2023.09.16

* Update `cffi` recipe for Python 3.10 (#2800)

* Update __init__.py

version bump to 1.15.1

* Update disable-pkg-config.patch

adjust patch for 1.15.1

* Use build rather than pep517 for building (#2784)

pep517 has been renamed to pyproject-hooks, and as a consequence all of
the deprecated functionality has been removed. build now provides the
functionality required, and since we are only interested in the
metadata, we can leverage a helper function for that. I've also removed
all of the subprocess machinery for calling the wrapping function, since
it appears to not be as noisy as pep517.

* Bump actions/setup-python and actions/checkout versions, as old ones are deprecated (#2827)

* Removes `mysqldb` recipe as does not support Python 3 (#2828)

* Removes `Babel` recipe as it's not needed anymore. (#2826)

* Remove dateutil recipe, as it's not needed anymore (#2829)

* Optimize CI runs, by avoiding unnecessary rebuilds (#2833)

* Remove `pytz` recipe, as it's not needed anymore (#2830)

* `freetype` recipe: Changed the url to use https as http doesn't work (#2846)

* Fix `vlc` recipe build (#2841)

* Correct sys_platform (#2852)

On Window, sys.platform = "win32".

I think "nt" is a reference to os.name.

* Fix code string - quickstart.rst

* Bump `kivy` version to `2.2.1` (#2855)

* Use a pinned version of `Cython` for now, as most of the recipes are incompatible with `Cython==3.x.x` (#2862)

* Automatically generate required pre-requisites (#2858)

`get_required_prerequisites()` maintains a list of Prerequisites required by each platform.

But that same information is already stored in each Prerequisite class.

Rather than rather than maintaining two lists which might become inconsistent, auto-generate one.

* Use `platform.uname` instead of `os.uname` (#2857)

Advantages:

- Works cross platform, not just Unix.
- Is a namedtuple, ... (continued)
