2975: RFC: Add GILProtected synchronization primitive and use it for LazyTypeObjectInner. r=davidhewitt a=adamreichold
I would also like to use that type in rust-numpy and it seems we can avoid ~~both a manual unsafe impl and~~ a full blown mutex if we apply it to `LazyTypeObjectInner`.
One downside might be that it ties us closer to the GIL when we want to enable nogil experimentation, but on the other hand, it may also help by reifying the GIL usage. (This is currently limited to comments in unsafe code in rust-numpy for example.)
3022: Fix function name shadowing r=davidhewitt a=mejrs
Fixes https://github.com/PyO3/pyo3/issues/3017
3023: Emit a better error for bad argument names r=davidhewitt a=mejrs
This will emit a better error for code like
```rust
#[pyfunction]
fn output([a,b,c]: [u8;3]) {}
```

3014: feat: add #[pyo3(get, set)] for Cell r=davidhewitt a=AntoineRR
This fixes#2659.
The types for which `#[pyo3(get, set)]` should now work are `Cell`, `Arc` and `Box`.
There is one issue regarding `Box`, the implementation of `FromPyObject` conflicts with another one. I could not find what the issue was, especially since the other implementations for `Arc` and `Cell` work as expected. The related code and test has been commented out for now. Maybe someone could help me fix this issue if I don't figure it out myself? There is also the possibility to remove the implementation for `Box` of course.

2930: add better error message for Python in signature r=adamreichold a=davidhewitt
Inspired by #2929, this just adds a better error message when `Python` arguments are accidentally included in the signature.

Since we're just testing a bug during traversal, we don't actually have
to reap the object, we just have to make a reference cycle so that it's
traverse method is called.
2796: Forward cfgs on pyclass fields to the method defs r=davidhewitt a=mejrs
With this and the cfg_attr PR, I don't need cfg_eval at all anymore :)
- [x] needs some more tests

2739: error when `#[pyo3(signature = ())]` used on invalid methods r=davidhewitt a=davidhewitt
A follow-up to #2702 to reject some invalid applications of `#[pyo3(signature = (...))]` attribute, specifically on magic methods and getters / setters / class attributes.

- Implement __ne__ as well as __eq__.
- Return NotImplemented when types cannot be converted, rather than
throwing.
- Compare the integer ids inside the __eq__/__ne__ implementation.
Previously a match block was generated.
