function_record_PyTypeObject: Replace C++20 designated initializers with full list of values.
rwgk
committed
Introduce `PYBIND11_DETAIL_FUNCTION_RECORD_ABI_ID` and use along with `PYBIND11_PLATFORM_ABI_ID_V4` to version `function_record_PyTypeObject` `tp_name`
rwgk
committed
Move `std::once_flag` out of `inline` function (in hopes that that fixes flaky behavior of test_gil_scoped.py). IncludeCleaner fixes.

`tp_vectorcall` was introduced only with Python 3.8

clang-tidy auto-fixes
rwgk
committed
Disable `-Wmissing-field-initializers`. Guard `PyType_Ready(&function_record_PyTypeObject)` also with a simple `static bool first_call`
rwgk
committed
Give up on the `std::call_once` idea, for Python 3.6 compatibility (it works with all other Python versions). Instead call `function_record_PyTypeObject_PyType_Ready()` from `get_internals()`.
rwgk
committed
Add `__reduce_ex__` to `function_record_PyTypeObject`. Add `_pybind11_detail_function_record_import_helper` (proof of concept).
rwgk
committed
Move `function_record_PyTypeObject_PyType_Ready()` call in `get_internals()` so that it is always called when `get_internals()` is called the first time.
