* Add feature controlling the global reference pool to enable avoiding its overhead.
* Document reference-pool feature in the performance guide.
* Invert semantics of feature to disable reference pool so the new behaviour becomes opt-in
* Remove delayed reference count increments as we cannot prevent reference count errors as long as these are available
* Adjust tests to be compatible with disable-reference-pool feature
* Adjust tests to be compatible with py-clone feature
* Adjust the GIL benchmark to the updated reference pool semantics.
* Further extend and clarify the documentation of the py-clone and disable-reference-pool features
* Replace disable-reference-pool feature by pyo3_disable_reference_pool conditional compilation flag
Such a flag is harder to use and thereby also harder to abuse. This seems
appropriate as this is purely a performance-oriented change which show only be
enabled by leaf crates and brings with it additional highly implicit sources of
process aborts.
* Add pyo3_leak_on_drop_without_reference_pool to turn aborts into leaks when the global reference pool is disabled and the GIL is not held
* graalpy: recognize graalpy implementation when building
* graalpy: global Ellipse, None, NotImplemented, True, and False are only available as pointers
* graalpy: PyObject struct is opaque, use functions for everything
* graalpy: missing many of the same functions as pypy
* graalpy: do not have 128bit conversion functions
* graalpy: add functions for datetime accessor macros
* graalpy: add implementations for list macro functions
* graalpy: skip tuple macros
* graalpy: always use extern Py_CompileString function
* graalpy: disable assertion that does not apply to graalpy
* graalpy: floatobject structure is opaque on graalpy
* graalpy: ignore gc dependent test
* graalpy: add CI config
* graalpy: run rust fmt
* graalpy: add changelog entry
* graalpy: discover interpreter on PATH
* graalpy: interpreter id is not applicable to graalpy (just like pypy)
* graalpy: skip tests that cannot work on GraalPy
* graalpy: fix constructing normalized Err instances

* graalpy: correct capi library name, but skip rust tests due to missing symbols
* graalpy: no support for C extensions on windows in latest release
* graalpy: declare support versions
* graalpy: frame, code, method, and function objects access from C API is mostly missing
* graalpy: take care only to expose C structure that GraalPy allocates
* graalpy: Bail out if graalpy version is less than what we support
