* Initializing PyModuleDef object with PyModuleDef_HEAD_INIT.
Python 3.8 documentation: m_base - Always initialize this member to PyModuleDef_HEAD_INIT.
Long-standing (since first github commit in 2015), inconsequential bug.
Also removing inconsequential Py_INCREF(def): PyModule_Create() resets the reference count to 1.
* git rebase master
* moving static PyModuleDef declaration to global scope, as requested by @wjakob
* renaming the two new macros, to start with PYBIND11_DETAIL_MODULE
This changes enum reprs to look like `<Enum.name: value>` similarly to
the Python enum module.
This keeps the str of enums as `Enum.name`, like the Python enum module.
Support C++20. For backwards compatibility, we provide an alias for the old name.
This change is necessary to easily avoid errors when a compiler thinks
`module` is used as a keyword.

* Add check if `str(handle)` correctly converted the object, and throw py::error_already_set if not
* Fix tests on Python 3
* Apply @rwgk's fixes to cherry-picked commits from #2392
The variables PYBIND11_HAS_OPTIONAL, PYBIND11_HAS_EXP_OPTIONAL, PYBIND11_HAS_VARIANT,
__clang__, __APPLE__ were not checked for defined in a minortity of instances.
If the project using pybind11 sets -Wundef, the warnings will show.
The test build is also modified to catch the problem.

Adding missing `bytes` type to `test_constructors()`, to exercise the code change.
The changes in the PR were cherry-picked from PR #2409 (with a very minor
modification in test_pytypes.py related to flake8). Via PR #2409, these
changes were extensively tested in the Google environment, as summarized here:
https://docs.google.com/document/d/1TPL-J__mph_yHa1quDvsO12E_F5OZnvBaZlW9IIrz8M/
The changes in this PR did not cause an issues at all.
Note that `test_constructors()` before this PR passes for Python 2 only
because `pybind11::str` can hold `PyUnicodeObject` or `PyBytesObject`. As a
side-effect of this PR, `test_constructors()` no longer relies on this
permissive `pybind11::str` behavior. However, the permissive behavior is still
exercised/exposed via the existing `test_pybind11_str_raw_str()`.
The test code change is designed to enable easy removal later, when Python 2
support is dropped.
For completeness: confusingly, the non-test code changes travelled through PR
Example `ambiguous conversion` error fixed by this PR:
```
pybind11/tests/test_pytypes.cpp:214:23: error: ambiguous conversion for functional-style cast from 'pybind11::detail::item_accessor' (aka 'accessor<accessor_policies::generic_item>') to 'py::bytes'

* Modified Vector STL bind initialization from a buffer type with optimization for simple arrays
* Add subtests to demonstrate processing Python buffer protocol objects with step > 1
* Fixed memoryview step test to only run on Python 3+
* Modified Vector constructor from buffer to return by value for readability
If the default argument value is a class, and not an instance of a
class, `a.value.attr("__repr__")` raises a `ValueError`. Switching to
`repr(a.value)` makes this use case work.
Fixes#2028

* Add memory view section in doc
* Fix docs
* Add test for null buffer

This avoids a potential conflict with names in the same scope of the

variables.

The PyEval_InitThreads() and PyEval_ThreadsInitialized() functions are
now deprecated and will be removed in Python 3.11. Calling
PyEval_InitThreads() now does nothing. The GIL is initialized by
Py_Initialize() since Python 3.7.
For rationale, see #2241, eeb1044818af5b70761deae602c49eba439164dc;
there is a second entry point function defined by the PYBIND11_MODULE
macro that also needs to be annotated as unused.
This change defines a new, portable macro PYBIND11_MAYBE_UNUSED to
mark declarations as unused, and annotates the PYBIND11_MODULE entry
point with this attribute.
The purpose of this annotation is to facilitate dead code detection,
which might otherwise consider the module entry point function dead,
since it isn't otherwise used. (It is only used via FFI.)
This adds support for a `py::args_kw_only()` annotation that can be
specified between `py::arg` annotations to indicate that any following
arguments are keyword-only. This allows you to write:
m.def("f", [](int a, int b) { /* ... */ },
py::arg("a"), py::args_kw_only(), py::arg("b"));
and have it work like Python 3's:
def f(a, *, b):
# ...
with respect to how `a` and `b` arguments are accepted (that is, `a` can
be positional or by keyword; `b` can only be specified by keyword).
Currently user specializations of the form
template <typename itype> struct polymorphic_type_hook<itype, std::enable_if_t<...>> { ... };
will fail if itype is also polymorphic, because the existing specialization will also
be enabled, which leads to 2 equally viable candidates. With this change, user provided
specializations have higher priority than the built in specialization for polymorphic types.
When binding code immediately throws an exception of type
py::error_already_set (e.g. via py::module::import that fails), the
catch block sets an import error as expected. Unfortunately, following
this, the deconstructor of py::error_already_set decides to call
py::detail::get_internals() and set up various internal data structures
of pybind11, which fails given that the error flag is active. The call
stack of this looks as follows:
Py_init_mymodule() -> __cxa_decrement_exception_refcount ->
error_already_set::~error_already_set() ->
gil_scoped_acquire::gil_scoped_acquire() -> detail::get_internals() ->
... -> pybind11::detail::simple_collector() -> uh oh..
The solution is simple: we call detail::get_internals() once before
running any binding code to make sure that the internal data structures
are ready.
This commit introduces the use of C++17-style fold expressions when
casting tuples & the argument lists of functions.
This change can improve performance of the resulting bindings: because
fold expressions have short-circuiting semantics, pybind11 e.g. won't
try to cast the second argument of a function if the first one failed.
This is particularly effective when working with functions that have
many overloads with long argument lists.
