* Insert type_caster_odr_guard<> (an empty struct to start with).
* Add odr_guard_registry() used in type_caster_odr_guard() default constructor.
* Add minimal_real_caster (from PR #3862) to test_async, test_buffers
* VERY MESSY SNAPSHOT of WIP, this was the starting point for cl/454658864, which has more changes on top.
* Restore original test_async, test_buffers from current smart_holder HEAD
* Copy from cl/454991845 snapshot Jun 14, 5:08 PM
* Cleanup of tests. Systematically insert `if (make_caster<T>::translation_unit_local) {`
* Small simplification of odr_guard_impl()
* WIP
* Add PYBIND11_SOURCE_FILE_LINE macro.
* Replace PYBIND11_TYPE_CASTER_UNIQUE_IDENTIFIER with PYBIND11_TYPE_CASTER_SOURCE_FILE_LINE, baked into PYBIND11_TYPE_CASTER macro.
* Add more PYBIND11_DETAIL_TYPE_CASTER_ACCESS_TRANSLATION_UNIT_LOCAL; resolves "unused" warning when compiling test_custom_type_casters.cpp
* load_type fixes & follow-on cleanup
* Strip ./ from source_file_line
* Add new tests to CMakeLists.txt, disable PYBIND11_WERROR
* Replace C++17 syntax. Compiles with Debian clang 13 C++11 mode, but fails to link. Trying GitHub Actions anyway to see if there are any platforms that support https://en.cppreference.com/w/cpp/language/tu_local before C++20. Note that Debian clang 13 C++17 works locally.
* Show C++ version along with ODR VIOLATION DETECTED message.
* Add source_file_line_basename()
* Introduce PYBIND11_TYPE_CASTER_ODR_GUARD_ON (but not set automatically).
* Minor cleanup.
* Set PYBIND11_TYPE_CASTER_ODR_GUARD_ON automatically.
* Resolve clang-tidy error.
* Compatibility with old compilers.
* Fix off-by-one in source_file_line_basename()
* Report PYBIND11_INTERNALS_ID & C++ Version from pytest_configure()
* Restore use of PYBIND11_WERROR
* Move cpp_version_in_use() from cast.h to pybind11_tests.cpp
* define PYBIND11_DETAIL_ODR_GUARD_IMPL_THROW_DISABLED true in test_odr_guard_1,2.cpp
* IWYU cleanup of detail/type_caster_odr_guard.h
* Replace `throw err;` to resolve clang-tidy error.
* Add new header filename to CMakeLists.txt, test_files.py
* Experiment: Try any C++17 compiler.
* Fix ifdef for pragma GCC diagnostic.
* type_caster_odr_guard_impl() cleanup
* Move type_caster_odr_guard to type_caster_odr_guard.h
* Rename test_odr_guard* to test_type_caster_odr_guard*
* Remove comments that are (now) more distracting than helpful.
* Mark tu_local_no_data_always_false operator bool as explicit (clang-tidy). See also: https://stackoverflow.com/questions/39995573/when-can-i-use-explicit-operator-bool-without-a-cast
* New PYBIND11_TYPE_CASTER_ODR_GUARD_STRICT option (current on by default).
* Add test_type_caster_odr_registry_values(), test_type_caster_odr_violation_detected_counter()
* Report UNEXPECTED: test_type_caster_odr_guard_2.cpp prevailed (but do not fail).
* Apply clang-tidy suggestion.
* Attempt to handle valgrind behavior.
* Another attempt to handle valgrind behavior.
* Yet another attempt to handle valgrind behavior.
* Trying a new direction: show compiler info & std for UNEXPECTED: type_caster_odr_violation_detected_count() == 0
* compiler_info MSVC fix. num_violations == 0 condition.
* assert pybind11_tests.compiler_info is not None
* Introduce `make_caster_intrinsic<T>`, to be able to undo the 2 changes from `load_type` to `load_type<T>`. This is to avoid breaking 2 `pybind11::detail::load_type()` calls found in the wild (Google global testing).
One of the breakages in the wild was: 0f0f600767/python/tensorstore/subscript_method.h (L61)
* Add test for stl.h / stl_bind.h mix.
Manually verified that the ODR guard detects the ODR violation:

* refactor: address review
* fix: the types for return_value_policy_override in optional_caster
`return_value_policy_override` was not being applied correctly in
`optional_caster` in two ways:
- The `is_lvalue_reference` condition referenced `T`, which was the
`optional<T>` type parameter from the class, when it should have used `T_`,
which was the parameter to the `cast` function. `T_` can potentially be a
reference type, but `T` will never be.
- The type parameter passed to `return_value_policy_override` should be
`T::value_type`, not `T`. This matches the way that the other STL container
type casters work.
The result of these issues was that a method/property definition which used a
`reference` or `reference_internal` return value policy would create a Python
value that's bound by reference to a temporary C++ object, resulting in
undefined behavior. For reasons that I was not able to figure out fully, it
seems like this causes problems when using old versions of `boost::optional`,
but not with recent versions of `boost::optional` or the `libstdc++`
implementation of `std::optional`. The issue (that the override to
`return_value_policy::move` is never being applied) is present for all
implementations, it just seems like that somehow doesn't result in problems for
the some implementation of `optional`. This change includes a regression type
with a custom optional-like type which was able to reproduce the issue.
Part of the issue with using the wrong types may have stemmed from the type
variables `T` and `T_` having very similar names. This also changes the type
variables in `optional_caster` to use slightly more descriptive names, which
also more closely follow the naming convention used by the other STL casters.

* Adding MSVC C4127 suppression around Eigen includes.
* For MSVC 2015 only: also adding the C4127 suppression to test_eigen.cpp
* Copying original change from PR #3343, with extra line breaks to not run past 99 columns (our desired but currently not enforced limit).
* Fix `pybind11::object::operator=` to be safe if `*this` is accessible from Python
* Add `custom_type_setup` attribute
This allows for custom modifications to the PyHeapTypeObject prior to
calling `PyType_Ready`. This may be used, for example, to define
`tp_traverse` and `tp_clear` functions.
* Fix thread safety for pybind11 loader_life_support
Fixes issue: https://github.com/pybind/pybind11/issues/2765
This converts the vector of PyObjects to either a single void* or
a per-thread void* depending on the WITH_THREAD define.
The new field is used by each thread to construct a stack
of loader_life_support frames that can extend the life of python
objects.
The pointer is updated when the loader_life_support object is allocated
(which happens before a call) as well as on release.
Each loader_life_support maintains a set of PyObject references
that need to be lifetime extended; this is done by storing them
in a c++ std::unordered_set and clearing the references when the
method completes.
* Also update the internals version as the internal struct is no longer compatible
* Add test demonstrating threading works correctly.
It may be appropriate to run this under msan/tsan/etc.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Update test to use lifetime-extended references rather than
std::string_view, as that's a C++ 17 feature.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Make loader_life_support members private
* Update version to dev2

Now also passes the open_spiel iterated_prisoners_dilemma_test ASAN clean, in addition to all pybind11 and PyCLIF unit tests.
The problem was that calling `std::shared_ptr<void>::reset()` with a `void` pointer cannot possibly update the `shared_from_this` `weak_ptr`.
The solution is to store a `shd_ptr_reset` function pointer in `guarded_deleter` (similar in idea to the stored function pointer for calling `delete`).
This commit still includes all debugging code, i.e. is "dirty". The code will be cleaned up after the GitHub CI is fully successful.
