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.

2934: guide: add documentation for trailing option arguments r=davidhewitt a=davidhewitt
Following the increased clarity around PyO3's handling of function signatures of 0.18.0, I wanted to add a section to the guide documenting the default-to-none behaviour for trailing `Option<T>` arguments.

2937: link against pythonXY_d.dll for debug Python on Windows r=davidhewitt a=davidhewitt
Closes#2780
Note that upstream Python issue https://github.com/python/cpython/issues/101614 means linking against `python3_d.dll` is useless, so I've set this to always use the version-specific builds for now.
The heuristic for detecting a Windows debug build is... not great. I check if the `EXT_SUFFIX` starts with `_d.`, which is the only thing that I could see in the sysconfig which suggested a debug build. If this proves to be brittle, we may wish to ask upstream for something better to be added to `sysconfig`.

2929: docs: Precise the abscense of `py: Python` for the #[pyo3(signature)] r=davidhewitt a=jjerphan
Hi,
First, thank you for working on PyO3!
I think this adds a precision which was not obvious when migrating to 0.18.0 conventions.
What do you think? Also, should something be added to [the migration guide](https://pyo3.rs/main/migration) in this regard?
Thank you!

2914: correct ffi definition of PyIter_Check r=davidhewitt a=davidhewitt
Closes#2913
It looks like what is happening is that PyO3 was relying on an outdated macro form of `PyIter_Check` which is now a CPython implementation detail, which would explain why it was behaving inconsistently on different platforms (likely due to differences in linkers / implementations).
The test I've pushed succeeds, but fails to compile due to a hygiene bug! I'm done for tonight so I'll take a look at that soon and then rebase this after.

After discussion in https://github.com/PyO3/rust-numpy/pull/367#issuecomment-1409283700 I noticed we were missing a CHANGELOG entry for frozen. This doesn't help past users but does help document when the feature was released (in 0.17.0).

2912: Add `PyDict.update()` and `PyDict.update_if_missing()` r=davidhewitt a=samuelcolvin
Fix#2910
Note, I'd also be happy to remove the `override_` argument from merge and perhaps rename it to `update_missing` or similar to give a cleaner API. LMK what you think.

2873: A new example that shows how to integrate Python plugins that use pyclasses into a Rust app r=davidhewitt a=alexpyattaev
Example showing integration of a Python plugin into a Rust app while having option to test pyclass based API without the main app. This also illustrates some aspects related to import of Python modules into a Rust app while also having an API module available for the Python code to be able to produce Rust objects.
CI seems to fail on my local machine for reasons unrelated to the example just added:

2923: hygiene: fix `#[pymethods(crate = "...")]` r=davidhewitt a=davidhewitt
Got to the bottom of the hygiene issue in test of #2914
Turns out that `#[pymethods] #[pyo3(crate = "...")]` works, but `#[pymethods(crate = "...")]` was ignoring the argument.
Added a tweak to fix this and a snippet in the hygiene test (which fails on `main`).

2904: refactor docstring generation code r=mejrs a=davidhewitt
As a first step towards #2866 this is a tweak to the macro code which generates Python docstrings. This PR refactors the behaviour so that instead of always creating a `concat!` expression to generate a nul-terminated string, this will only happen if a Rust 1.54+ macro doc is present (e.g. `#[doc = include_str!(...)]`).
The default case now just collects all the `#[doc]` attributes into a single string.
This should make it easier to factor out the `text_signature` formatting, and avoids wasting compile time invoking the `concat!` macro when not necessary.
2921: Check to see if object is `None` before traversing r=davidhewitt a=neachdainn
Closes#2915
When using the C API directly, the intended way to call `visitproc` is via the `Py_VISIT` macro, which checks to see that the provided pointer is not null before passing it along to `visitproc`. Because PyO3 isn't using the macro, it needs to manually check that the pointer isn't null. Without this check, calling `visit.call(&obj)` where `let obj = None;` will segfault.
