Python3.11

[hoodmane]

So far this update is not too bad. I got all the core tests working. The following packages are currently not building:

• freesasa (resolved on tip of tree Python 3.11 support? freesasa/freesasa-python#32 but no stable release yet)
• numcodecs (Python 3.11 support? zarr-developers/numcodecs#397 redirected to Release 0.11 with Python 3.11 support zarr-developers/numcodecs#377)
• pyb2d (Python 3.11 support? pyb2d/pyb2d#62 ) Pyb2d v0.7.4 #3361
• pycryptodomex (Python 3.11 support? Legrandin/pycryptodome#680) (failing for unreleated reasons)
• sparseqr (no issue yet) We are building this from a fork so I am not going to fix it. @gabrielfougeron or @ryanking13 can fix it in a followup PR.
• wordcloud (See Fails to build with python3.11 amueller/word_cloud#691)
• crytography and bcrypt: a rust problem appeared over night. I am not sure what changed.
• gensim gensim 4.3.0 #3360

The core tests are almost all passing, except chrome sees a stack overflow in test-xml-etree. Maybe we should just xfail that one in chrome.

The no-numpy-dependents packages have three failures:

• bitarray: null function or function pointer signature mismatch. (Fixed!)
• distutils: can't find the tests (fixed by @ryanking13)
• sqlite: can't find the tests (fixed by @ryanking13)

I added two CPython patches to fix problems with call trampolines. I opened the following PRs upstream for this:

• gh-99443: descr_set_trampoline_call return type should be int not PyObject* python/cpython#99444
• gh-99460 Emscripten trampolines on optimized METH_O and METH_NOARGS code paths python/cpython#99461

• Fix github actions (done by @ryanking13)
• Fix benchmark-stack-size
• Fix pre-commit

Checklists

• Add a CHANGELOG entry

Okay I got everything fixed or xfailed so I will go ahead and merge this.

Thanks a lot @hoodmane for doing all this migration!
