Hi!

While rebuilding the python related packages against the Python 3.15rc1
version we found that python-anyio fails to build from source [1].

I backported the relevant parts of the upstream commits that add support
for 3.15 [2] [3]. Note that upstream disables blockbuster in the
pyproject.toml, but that doesn't work for our builds. Also, blockbuster
will get support for python 3.15 once forbiddenfruit add it[5].

I applied the upstream fixes in the sandbox [4] to be able to build the
packages that depend on python-anyio, please consider applying the
patches to support the upcoming 3.15 version.

Happy hacking,
