pybind11.pc: use pcfiledir for relative destinations (#4830)
* pybind11.pc: use pcfiledir for relative destinations

If the datarootdir is absolute, just use the absolute path directly.
However, if it is relative, we can compute the prefix from the location
of the `.pc` file itself. This allows the install to be relocatable.

* style: pre-commit fixes

* Update CMakeLists.txt

Fix a long-standing bug in the handling of Python multiple inheritance (#4762)
* Equivalent of 5718e4d080

* Resolve clang-tidy errors.

* Moving test_PPCCInit() first changes the behavior!

* Resolve new Clang dev C++11 errors:

```
The CXX compiler identification is Clang 17.0.0
```

```
pytypes.h:1615:23: error: identifier '_s' preceded by whitespace in a literal operator declaration is deprecated [-Werror,-Wdeprecated-literal-operator]
```

```
cast.h:1380:26: error: identifier '_a' preceded by whitespace in a literal operator declaration is deprecated [-Werror,-Wdeprecated-literal-operator]
```

* Resolve gcc 4.8.5 error:

```
pytypes.h:1615:12: error: missing space between '""' and suffix identifier
```

* Specifically exclude `__clang__`

* Snapshot of debugging code (does NOT pass pre-commit checks).

* Revert "Snapshot of debugging code (does NOT pass pre-commit checks)."

This reverts commit 1d4f9ff263.

* [ci skip] Order Dependence Demo

* Revert "[ci skip] Order Dependence Demo"

This reverts commit d37b5409d4.

* One way to deal with the order dependency issue. This is not the best way, more like a proof of concept.

* Move test_PC() first again.

* Add `all_type_info_add_base_most_derived_first()`, use in `all_type_info_populate()`

* Revert "One way to deal with the order dependency issue. This is not the best way, more like a proof of concept."

This reverts commit eb09c6c1b9.

* clang-tidy fixes (automatic)

* Add `is_redundant_value_and_holder()` and use to avoid forcing `__init__` overrides when they are not needed.

* Streamline implementation and avoid unsafe `reinterpret_cast<instance *>()` introduced with PR #2152

The `reinterpret_cast<instance *>(self)` is unsafe if `__new__` is mocked,
which was actually found in the wild: the mock returned `None` for `self`.
This was inconsequential because `inst` is currently cast straight back to
`PyObject *` to compute `all_type_info()`, which is empty if `self` is not
a pybind11 `instance`, and then `inst` is never dereferenced. However, the
unsafe detour through `instance *` is easily avoided and the updated
implementation is less prone to accidents while debugging or refactoring.

* Fix actual undefined behavior exposed by previous changes.

It turns out the previous commit message is incorrect, the `inst` pointer is actually dereferenced, in the `value_and_holder` ctor here:

f3e0602802/include/pybind11/detail/type_caster_base.h (L262-L263)

```
259     // Main constructor for a found value/holder:
260     value_and_holder(instance *i, const detail::type_info *type, size_t vpos, size_t index)
261         : inst{i}, index{index}, type{type},
262           vh{inst->simple_layout ? inst->simple_value_holder
263                                  : &inst->nonsimple.values_and_holders[vpos]} {}
```

* Add test_mock_new()

* Experiment: specify indirect bases

* Revert "Experiment: specify indirect bases"

This reverts commit 4f90d85f9f.

* Add `all_type_info_check_for_divergence()` and some tests.

* Call `all_type_info_check_for_divergence()` also from `type_caster_generic::load_impl<>`

* Resolve clang-tidy error:

```
include/pybind11/detail/type_caster_base.h:795:21: error: the 'empty' method should be used to check for emptiness instead of 'size' [readability-container-size-empty,-warnings-as-errors]
                if (matching_bases.size() != 0) {
                    ^~~~~~~~~~~~~~~~~~~~~~~~~~
                    !matching_bases.empty()
```

* Revert "Resolve clang-tidy error:"

This reverts commit df27188dc6.

* Revert "Call `all_type_info_check_for_divergence()` also from `type_caster_generic::load_impl<>`"

This reverts commit 5f5fd6a68e.

* Revert "Add `all_type_info_check_for_divergence()` and some tests."

Add PyThreadState_GetUnchecked() function: similar to
PyThreadState_Get(), but don't kill the process with a fatal error if
it is NULL. The caller is responsible to check if the result is
NULL. Previously, the function was private and known as

that makes `cast_op` fail to compile:

Defining the nested type as an alias and using it allows this to work
without any change in semantics.

Update pytest to version 7.2.0 (which removes their dependency on py) (#4880)
* Update pytest (which removes their dependency on py)

The py library through 1.11.0 for Python allows remote attackers to conduct a ReDoS (Regular expression Denial of Service) attack via a Subversion repository with crafted info data, because the InfoSvnCommand argument is mishandled.

The particular codepath in question is the regular expression at py._path.svnurl.InfoSvnCommand.lspattern and is only relevant when dealing with subversion (svn) projects. Notably the codepath is not used in the popular pytest project. The developers of the pytest package have released version 7.2.0 which removes their dependency on py. Users of pytest seeing alerts relating to this advisory may update to version 7.2.0 of pytest to resolve this issue. See https://github.com/pytest-dev/py/issues/287#issuecomment-1290407715 for additional context.

* Added conditions so that we keep using 7.0.0 on python 3.6

* Revert "Add `PYBIND11_CONSTINIT`, but it does not work for the current use cases:"

This reverts commit f07b28bda9.

* Reapply "Add `PYBIND11_CONSTINIT`, but it does not work for the current use cases:"

This reverts commit 36be645758.

* Add Default Member Initializer on `value_storage_` as suggested by @tkoeppe:

https://github.com/pybind/pybind11/pull/4877#issuecomment-1753201342

This fixes the errors reported under commit f07b28bda9.

* Fix copy-paste-missed-a-change mishap in commit 88cec1152a.

* Semi-paranoid placement new (based on https://github.com/pybind/pybind11/pull/4877#discussion_r1350573114).

* Move PYBIND11_CONSTINIT to detail/common.h

* Move code to the right places, rename new class and some variables.

* Fix oversight: update tests/extra_python_package/test_files.py

* Get the name right first.

* Use `std::call_once`, `std::atomic`, following a pattern developed by @tkoeppe

* Make the API more self-documenting (and possibly more easily reusable).

* google-clang-tidy IWYU fixes

* Rewrite comment as suggested by @tkoeppe

* Update test_exceptions.cpp and exceptions.rst

* Fix oversight in previous commit: add `PYBIND11_CONSTINIT`

* Make `get_stored()` non-const for simplicity.

As suggested by @tkoeppe: not seeing any reasonable use in which `get_stored` has to be const.

* Add comment regarding `KeyboardInterrupt` behavior, based heavily on information provided by @jbms.

* Add `assert(PyGILState_Check())` in `gil_scoped_release` ctor (simple & non-simple implementation) as suggested by @EthanSteinberg.

* Fix oversight in previous commit (missing include cassert).

* Remove use of std::atomic, leaving comments with rationale, why it is not needed.

* Rewrite comment re `std:optional` based on deeper reflection (aka 2nd thoughts).

* Additional comment with the conclusion of a discussion under PR #4877.

* https://github.com/pybind/pybind11/pull/4877#issuecomment-1757363179

* Small comment changes suggested by @tkoeppe.
