Background: #2999, #4105, #4283, #4284
In a nutshell:
* Only macOS actually needs `PYBIND11_EXPORT_EXCEPTION` (#4284).
* Evidently (#4283), under macOS `PYBIND11_EXPORT_EXCEPTION` does not run the risk of introducing ODR violations,
* but evidently (#4283) under Linux it does, in the presumably rare/unusual situation that `RTLD_GLOBAL` is used.
* Windows does no have the equivalent of `RTLD_GLOBAL`, therefore `PYBIND11_EXPORT_EXCEPTION` has no practical benefit, on the contrary, noisy warning suppression pragmas are needed, therefore it is best left empty.
* chore: drop Python 3.5 support
* chore: more fstrings with flynt's help
* ci: drop Python 3.5
* chore: bump dependency versions
* docs: touch up py::args
* tests: remove deprecation warning
* Ban smartquotes
* Very minor tweaks (by-product of reviewing PR #3719).

* Simply has_kw_only_args handling
This simplifies tracking the number of kw-only args by instead tracking
the number of positional arguments (which is really what we care about
everywhere this is used).
* Allow keyword-only arguments to follow py::args
This removes the constraint that py::args has to be last (or
second-last, with py::kwargs) and instead makes py::args imply
py::kw_only for any remaining arguments, allowing you to bind a function
that works the same way as a Python function such as:
def f(a, *args, b):
return a * b + sum(args)
f(10, 1, 2, 3, b=20) # == 206
With this change, you can bind such a function using:
m.def("f", [](int a, py::args args, int b) { /* ... */ },
"a"_a, "b"_a);
Or, to be more explicit about the keyword-only arguments:
m.def("g", [](int a, py::args args, int b) { /* ... */ },
"a"_a, py::kw_only{}, "b"_a);
(The only difference between the two is that the latter will fail at
binding time if the `kw_only{}` doesn't match the `py::args` position).
This doesn't affect backwards compatibility at all because, currently,
you can't have a py::args anywhere except the end/2nd-last.
* Take args/kwargs by const lvalue ref

* Fix `pybind11::object::operator=` to be safe if `*this` is accessible from Python
* Add `custom_type_setup` attribute
This allows for custom modifications to the PyHeapTypeObject prior to
calling `PyType_Ready`. This may be used, for example, to define
`tp_traverse` and `tp_clear` functions.
* Add make_value_iterator (#3271)
* Add make_value_iterator
This is the counterpart to make_key_iterator, and will allow
implementing a `value` method in `bind_map` (although doing so is left
for a subsequent PR).
I made a few design changes to reduce copy-and-paste boilerplate.
Previously detail::iterator_state had a boolean template parameter to
indicate whether it was being used for make_iterator or
make_key_iterator. I replaced the boolean with a class that determines
how to dereference the iterator. This allows for a generic
implementation of `__next__`.
I also added the ValueType and Extra... parameters to the iterator_state
template args, because I think it was a bug that they were missing: if
make_iterator is called twice with different values of these, only the
first set has effect (because the state class is only registered once).
There is still a potential issue in that the *values* of the extra
arguments are latched on the first call, but since most policies are
empty classes this should be even less common.
* Add some remove_cv_t to appease clang-tidy
* Make iterator_access and friends take reference
For some reason I'd accidentally made it take a const value, which
caused some issues with third-party packages.
* Another attempt to remove remove_cv_t from iterators
Some of the return types were const (non-reference) types because of the
pecularities of decltype: `decltype((*it).first)` is the *declared* type
of the member of the pair, rather than the type of the expression. So if
the reference type of the iterator is `pair<const int, int> &`, then the
decltype is `const int`. Wrapping an extra set of parentheses to form
`decltype(((*it).first))` would instead give `const int &`.
This means that the existing make_key_iterator actually returns by value
from `__next__`, rather than by reference. Since for mapping types, keys
are always const, this probably hasn't been noticed, but it will affect
make_value_iterator if the Python code tries to mutate the returned
objects. I've changed things to use double parentheses so that
make_iterator, make_key_iterator and make_value_iterator should now all
return the reference type of the iterator. I'll still need to add a test
for that; for now I'm just checking whether I can keep Clang-Tidy happy.
* Add back some NOLINTNEXTLINE to appease Clang-Tidy
This is favoured over using remove_cv_t because in some cases a const
value return type is deliberate (particularly for Eigen).
* Add a unit test for iterator referencing
Ensure that make_iterator, make_key_iterator and make_value_iterator
return references to the container elements, rather than copies. The
test for make_key_iterator fails to compile on master, which gives me
confidence that this branch has fixed it.
* Make the iterator_access etc operator() const
I'm actually a little surprised it compiled at all given that the
operator() is called on a temporary, but I don't claim to fully
understand all the different value types in C++11.
* Attempt to work around compiler bugs
https://godbolt.org/ shows an example where ICC gets the wrong result
for a decltype used as the default for a template argument, and CI also
showed problems with PGI. This is a shot in the dark to see if it fixes
things.
* Make a test constructor explicit (Clang-Tidy)
* Fix unit test on GCC 4.8.5
It seems to require the arguments to the std::pair constructor to be
implicitly convertible to the types in the pair, rather than just
requiring is_constructible.
* Remove DOXYGEN_SHOULD_SKIP_THIS guards
Now that a complex decltype expression has been replaced by a simpler
nested type, I'm hoping Doxygen will be able to build it without issues.
* Add comment to explain iterator_state template params
* fix: regression in #3271

These are added via the register_local_exception_translator function
and are then applied before the global translators
* Add unit tests to show the local exception translator works
* Fix a bug in the unit test with the string value of KeyError
* Fix a formatting issue
* Rename registered_local_types_cpp()
Rename it to get_registered_local_types_cpp() to disambiguate from the
new member of module_internals

* Remove the code duplication when translating exceptions
Separated out the exception processing into a standalone function in the
details namespace.
Clean-up some comments as per PR notes as well
* Remove the code duplication in register_exception
* Cleanup some formatting things caught by clang-format
* Remove the templates from exception translators
But I added a using declaration to alias the type.
* Remove the extra local from local_internals variable names
* Add an extra explanatory comment to local_internals
* Fix a typo in the code
For single-file extensions, a convenient pattern offered by cython
is to place the source files directly in the python source tree
(`foo/__init__.py`, `foo/ext.pyx`), deriving the package names from
their filesystem location. Adapt this pattern for pybind11, using an
`intree_extensions` helper, which should be thought of as the moral
equivalent to `cythonize`.
Differences with cythonize: I chose not to include globbing support
(`intree_extensions(glob.glob("**/*.cpp"))` seems sufficient), nor to
provide extension-customization kwargs (directly setting the attributes
on the resulting Pybind11Extension objects seems sufficient).
We could choose to have `intree_extension` (singular instead) and make
users write `[*map(intree_extension, glob.glob("**/*.cpp"))]`; no strong
opinion here.

* Adding test_return_vector_bool_raw_ptr to test_stl.py.
* First attempt to make the documentation more accurate, but not trying to be comprehensive, to not bloat the reference table with too many details.
* Fixing minor oversights.
* Applying reviewer suggestion.
* Adding iostream.h thread-safety documentation.
* Restoring `TestThread` code with added `std::lock_guard<std::mutex>`.
* Updating new comments to reflect new information.
* Fixing up `git rebase -X theirs` accidents.
* docs: mention PYTHONPATH in installing.rst
When pybind11 is included as a submodule, the user needs to update their
Python module search path. Otherwise, the first c++ compilation command
in docs/basics.rst will fail.
* docs: add a note about compiling the example
This note shows how to modify the compilation command for the example
when the pybind11 source has been included as a Git submodule.
* docs: add a note about compiling the example
Added an internal link to the docs
* docs: updated a note about compiling the example
Also updated the command substitution syntax for consistency
