* 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
* deprecate GIL Refs in function arguments
* fix deprecated gil refs in function arguments
* add notes on deprecations limitations to migration guide
* Apply suggestions from code review

* deprecate `wrap_pyfunction` with `py` argument
The Python token in `wrap_pyfunction` is not handled automatically by
`WrapPyFunctionArg`, for backwards compatibility. This uses deref
specialization to deprecate this variant.
* merge `Extractor`s
* add deprecation ui test, revert closure variant due to test failure
* fix nightly
* deprecate `&PyModule` as `#[pymodule]` argument type
* cleanup
* add ui tests
* fix deprecations in tests
* fix maturin and setuptools-rust starters
* run `deprecated` ui test only when `gil-refs` as disabled
* Implement PyErr::value_bound
* Use PyErr::value_bound in conversions
* Implement PyErr::from_value_bound
* Remove unnecessary clone
* Return a reference from PyErr::value_bound
* Avoid clone in PyErr::from_value_bound
* Use PyErr::from_value_bound instead of from_value
* Remove unnecessary .as_borrowed() calls
* Remove unused import
* Simplify UnraisableCapture.hook
* Use Bound::from_owned_ptr_or_opt in fn cause
* Update PyErrState::lazy to take Py<PyAny>
This is easier to work with elsewhere than `&PyAny` or
`Bound<'py, PyAny>`.
* Add Bound PyUnicodeDecodeError constructors
* Update PyErr::from_value_bound to take Bound
* Simplify PyErr::from_value
* Simplify PyErr::value
* Remove unnecessary reference
* Simplify Pyerr::cause implementation
* Simplify PyUnicodeDecodeError::new_bound
* port `Python::import` to `Bound` API
* tidy up imports in tests/test_datetime_import.rs
