2990: Fix `clippy::redundant_closure` lint firing for pyfunction defaults r=adamreichold a=davidhewitt
Fixes#2988
I'll push a follow-up for the FIXME as a separate PR.
2991: unpin 3.11 ci jobs r=adamreichold a=davidhewitt
With Python 3.11.2 released for a couple weeks now, I think #2817 is probably not an issue in CI any more.

2982: explain STATUS_DLL_NOT_FOUND r=adamreichold a=mejrs

2899: RFC: Provide a special purpose FromPyObject impl for byte slices r=davidhewitt a=adamreichold
This enables efficiently and safely getting a byte slice from either bytes or byte arrays.
The main issue I see here is discoverability, i.e. should this be mention in the docs of `PyBytes` and `PyByteArray` or in the guide?
It is also not completely clear whether this really _fixes_ the issue.
Closes#2888

Also I removed my old project because it's way too outdated (around pyo3 0.10?)

2952: Fix allow_threads segfault r=davidhewitt a=OliverBalfour
Please see the corresponding issue **#2951** for details. This PR adds the failing test from the issue and then a fix for it. The fix simply calls `ReferencePool::update_counts` at the end of `allow_threads` to ensure objects aren't accidentally deleted too soon.

2964: Update `README.md` by adding datafusion, ballista and delta-rs r=adamreichold a=iajoiner
Add Python bindings of datafusion, ballista and the official Rust implementation of Delta Lake (delta-rs). The former two are Apache projects under Arrow and the last is from Delta Lake itself so all three projects are notable and need to be added as examples.

2961: docs: fix typo in method name r=adamreichold a=lycantropos
There's no `PyFunction::new_closure`, but there is [`PyCFunction::new_closure`](3b2c175f8d/src/types/function.rs (L50-L104)), so I guess it's a typo in docs.

2947: change PyModule::add_class to return an error if class creation fails r=adamreichold a=davidhewitt
Related to #2942
At the moment there are panics deep in the `#[pyclass]` machinery when initialising the type fails. This PR adjusts a number of these functions to return `PyResult` instead, so that we can handle the error more appropriately further down the pipeline.
For example, take the following snippet:
```rust
#[pyclass(extends = PyBool)]
struct ExtendsBool;
#[pymodule]
fn pyo3_scratch(_py: Python, m: &PyModule) -> PyResult<()> {
m.add_class::<ExtendsBool>()?;
Ok(())
}
```
Currently, importing this module will fail with a panic:
```
TypeError: type 'bool' is not an acceptable base type
thread '<unnamed>' panicked at 'An error occurred while initializing class ExtendsBool', /Users/david/Dev/pyo3/src/pyclass.rs:412:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/Users/david/.virtualenvs/pyo3/lib/python3.10/site-packages/pyo3_scratch/__init__.py", line 1, in <module>
from .pyo3_scratch import *
pyo3_runtime.PanicException: An error occurred while initializing class ExtendsBool
```
After this PR, this import still fails, but with a slightly cleaner, more Pythonic error:
```
TypeError: type 'bool' is not an acceptable base type
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/Users/david/.virtualenvs/pyo3/lib/python3.10/site-packages/pyo3_scratch/__init__.py", line 1, in <module>
from .pyo3_scratch import *
RuntimeError: An error occurred while initializing class ExtendsBool
```

2944: optimize sequence conversion for list and tuple r=adamreichold a=davidhewitt
closes#2943
Avoid using `PyObject_IsInstance` for checking if lists or tuples are sequences, as we know they are always sequences.

2954: optimize mapping conversion for dict r=davidhewitt a=davidhewitt
Equivalent of #2944 for dicts -> mapping.
The benchmark diff is not as significant as in #2944. Still something like 80ns -> 2ns on my machine.

2948: don't parse doc attributes unnecessarily r=davidhewitt a=davidhewitt
While working on #2866 I found that for all `#[pymethods]` we process the `#[doc]` attributes and build a Python docstring. However we don't always emit this doc - e.g. for class attributes and `__dunder__` methods.
This is just a small adjustment to move the `#[doc]` processing slightly later in the macro code to avoid the wasted work. (It also helps for the #2866 implementation later.)

2945: move some private internals out of public implementation r=davidhewitt a=davidhewitt
This runs some quick cleanups on private stuff:
- Remove `#[doc(hidden)]` trait `TryFromPyCell` which is unused.
- Move `#[doc(hidden)]` struct `pyo3::type_object::LazyStaticType` to `pyo3::impl_::pyclass::LazyStaticType`.
- Move `pub(crate)` function `pyo3::pyclass::create_type_object` into submodule, to clean up main `pyclass.rs` implementation for readers.
As this is no behaviour change and separates stuff out slightly better, I'm just going to proceed to merge this. If anyone reading this wants to suggest a different way to factor out, happy to write a follow-up PR.
