* 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, so can use meaningful  fieldnames.

Also snuck in correction to typo in Readme which doesn't warrant its own review.

* Fix simple typos in comments (#2863)

One typo I introduced while trying to fix the other.

* `build_platform` should be all-lowercase (#2864)

* Docs: Fix typos and improved README quickstart (#2860)

* Made p4a apk build command more general - readme

* Fix twice spelled - readme

* updated p4a build command

* Cleanup `patching.py` (#2868)

Major changes to comments, param names, function ordering.
Removed deprecated LooseVersion
Move os.uname to platform.uname
Added win32 check
Windows fix

* Update Python versions in CI tests

Python 3.11 was released October 2022.
Python 3.7 went end-of-life June 2023

* Update documentation to reflect Python 3.7 being end-of-life.

* Correct check for `--sdk` option (#2870)

* Factor out dependency checking. Use modern version handling (#2866)

LooseVersion used again


Handle bad SDK versions

* Linter fixes (#2874)

The errors were:

* Remove deprecated FlatDir in Gradle template (#2876)

Based on lessons from https://stackoverflow.com/questions/68215302/using-flatdirs-should-be-avoided-because-it-doesnt-support-any-meta-data-format

* Standardise `ensure_dir` and `rmdir` (#2871)

* Standardise ensure_dir and rmdir

* Standardise ensure_dir and rmdir

* Add libmysqlclient to broken list

* Libtorrent failing to be rebuilt

* Add boost to broken recipes list

* Standardise on move (files, directories) (#2884)

* Add new util function (and tests) called `move`.
* Change references to sh.mv to use move (as it is faster and cross-platform).
* Change conditional "mv -t" to a for loop.

* Standardise on touch files (#2886)

Existing code shells out to run the `touch` Unix command.
This can be done faster (and cross-platform) with `pathlib`'s touch method.

* Created a utility to accept string paths or pathlib paths and applies touch.
* Created test for it.
* Update all instances to use it, and updated their tests.

* Update CHANGELOG.md and bump version to 2023.09.16
