* 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
* Update test to use python threading rather than concurrent.futures
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Remove unnecessary env in test
* Remove unnecessary pytest in test
* Use native C++ thread_local in place of python per-thread data structures to retain compatability
* clang-format test_thread.cpp
* Add a note about debugging the py::cast() error
