Python 3.11 build fails

[Cap-JaTu]

pip install systemd==0.16.1 on Python 3.11 explodes with tons of C warnings and errors. Apparently Python ABI changed and none of those changes are yet compensated to this library.

Partial list includes:

@Cap-JaTu the project has been renamed for avoid confisions to cysystemd. The first of all pelase use the lastest version it this.

In thesystemd==0.16.1 python 3.6 has been defined as the last supported version. Why the behaviour just reported above is unexpected?

Of course as a workaround you may install the latest Cython version before installing systemd==0.16.1, this should regen the .c files and probably should fix your problem, but I do not really recommend to do it for your projects.

[Cap-JaTu]

There is tons of confusion.

What you state about version 3.6 is correct. However, in https://github.com/mosquito/cysystemd/blob/master/README.rst there is a mention about 3.10.

Still, by clicking "Homepage" on https://pypi.org/project/systemd/, I'll land to this project. So, I'll assume the issues should be filed here. Did I get that wrong?

@Cap-JaTu fixed in 0.17.0

Thank you very much!

Fix confirmed.
