* Use `py::set_error()` everywhere possible (only one special case, in common.h).
Overload `py::set_error(py::handle, py::handle)`.
Change back to `static py::handle exc = ... .release();`
Deprecate `py::exception<>::operator()`
* Add `PYBIND11_WARNING_DISABLE` for INTEL and MSVC (and sort alphabetically).
* `PYBIND11_WARNING_DISABLE_INTEL(10441)` does not work.
For ICC only, falling back to the recommended `py::set_error()` to keep the testing simple.
It is troublesome to add `--diag-disable=10441` specifically for test_exceptions.cpp, even that is non-ideal because it covers the entire file, not just the one line we need it for, and the value of exercising the trivial deprecated `operator()` on this one extra platform is practically zero.
* Fix silly oversight.
* NVHPC 23.5.0 generates deprecation warnings. They are currently not treated as errors, but falling back to using `py::set_error()` to not have to deal with that distraction.

* Add command to check for vX.Y.Z tag vs pybind11/_version.py consistency. Piggy-backing hints for converting changelog to release message.

Lesson learned:
This is NOT GOOD:
```
- Bullet nesting level 1.
- Bullet nesting level 2.
```
This is BETTER:
```
- Bullet nesting level 1.
- Bullet nesting level 2.
```
Also consistently adding empty lines between bullet points, to make the .rst
file easier to read.
Also piggy-backing a few very minor enhancements.
* Remove .dev1 from version number.

* Miscellaneous minor fixes from proofreading in GitHub web view.

This reverts commit afc80134cb.
`PyUnicode_DecodeLatin1` requires you to pass in the `error`
parameter. The code as it is in the docs didn't compile.
There is a reference leak in the example
code. `PyUnicode_DecodeLatin1` returns a new reference. Calling
`py::str(PyObject*)` calls `PyObject_Str`, which also returns a new
reference. That reference is managed by the `py::str`
constructor (which correctly steals the reference, using the
`stolen_t` constructor), but the original reference returned by
`PyUnicode_DecodeLatin1` is never decref'd: it never makes it into an
`object`, and it's never manually decremented.
This fixes both of those issues. The code compiles, and I viewed the
sphinx docs locally.
* Try using `std::hash<std::type_index>`, `std::equal_to<std::type_index>` everywhere.
From PR #4316 we know that types in the unnamed namespace in different translation units do not compare equal, as desired.
But do types in named namespaces compare equal, as desired?
* Revert "Try using `std::hash<std::type_index>`, `std::equal_to<std::type_index>` everywhere."
This reverts commit a06949a926.
* Use "our own name-based hash and equality functions" for `std::type_index` only under macOS, based on results shown under https://github.com/pybind/pybind11/pull/4316#issuecomment-1305097879
* Patch in PR #4313: Minimal reproducer for clash when binding types defined in the unnamed namespace.

Background: #2999, #4105, #4283, #4284
In a nutshell:
* Only macOS actually needs `PYBIND11_EXPORT_EXCEPTION` (#4284).
* Evidently (#4283), under macOS `PYBIND11_EXPORT_EXCEPTION` does not run the risk of introducing ODR violations,
* but evidently (#4283) under Linux it does, in the presumably rare/unusual situation that `RTLD_GLOBAL` is used.
* Windows does no have the equivalent of `RTLD_GLOBAL`, therefore `PYBIND11_EXPORT_EXCEPTION` has no practical benefit, on the contrary, noisy warning suppression pragmas are needed, therefore it is best left empty.
