* Fix py::cast from pytype rvalue to pytype
Previously, py::cast blindly assumed that the destination type was a C++
type rather than a python type when the source type was an rvalue.

* Add frozenset, and allow it cast to std::set
For the reverse direction, std::set still casts to set. This is in concordance with the behavior for sequence containers, where e.g. tuple casts to std::vector but std::vector casts to list.
Extracted from #3886.
* Rename set_base to any_set to match Python C API
since this will be part of pybind11 public API
* PR: static_cast, anyset
* Add tests for frozenset
and rename anyset methods
* Remove frozenset default ctor, add tests
Making frozenset non-default constructible means that we need to adjust pyobject_caster to not require that its value is default constructible, by initializing value to a nil handle. This also allows writing C++ functions taking anyset, and is arguably a performance improvement, since there is no need to allocate an object that will just be replaced by load.
Add some more tests, including anyset::empty, anyset::size, set::add and set::clear.

* Clear Python error state if pybind11::weakref() fails.
The weakref() constructor calls pybind11_fail() without clearing any
Python interpreter error state. If a client catches the C++ exception
thrown by pybind11_fail(), the Python interpreter will be left in an
error state.

* Expand string_view support to str, bytes, memoryview
1. Allows constructing a str or bytes implicitly from a string_view;
this is essentially a small shortcut allowing a caller to write
`py::bytes{sv}` rather than `py::bytes{sv.data(), sv.size()}`.
2. Allows implicit conversion *to* string_view from py::bytes -- this
saves a fair bit more as currently there is no simple way to get such
a view of the bytes without copying it (or resorting to Python API
calls).
(This is not done for `str` because when the str contains unicode we
have to allocate to a temporary and so there might not be some string
data we can properly view without owning.)
3. Allows `memoryview::from_memory` to accept a string_view. As with
the other from_memory calls, it's entirely your responsibility to
keep it alive.
This also required moving the string_view availability detection into
detail/common.h because this PR needs it in pytypes.h, which is higher
up the include chain than cast.h where it was being detected currently.
* Move string_view include to pytypes.h
* CI-testing a fix for the "ambiguous conversion" issue.
This change is known to fix the `tensorflow::tstring` issue reported under https://github.com/pybind/pybind11/pull/3521#issuecomment-985100965

* Fix py::kw_only when used before the first arg of a method
The implicit space for the `self` argument isn't added until we hit the
first argument, but this wasn't being done for kw_only or pos_only, and
so a kw_only before the first argument would break.
This fixes it by properly checking whether we need to add the self arg.
(The pos_only issue here was extremely mild -- you didn't get the `/` in
the docstring, but AFAICT it has no other effect since there are no
meaningful arguments before it anyway).
* Style changes
- rename check_have_self_arg -> append_self_arg_if_needed
- move the argument name inline comments before the args instead of
after

* override: Fix wrong caching of the overrides
There was a problem when the python type, which was stored in override
cache for C++ functions, was destroyed and the record wasn't removed from the
override cache. Therefor, dangling pointer was stored there. Then when the
memory was reused and new type was allocated at the given address and the
method with the same name (as previously stored in the cache) was actually
overridden in python, it would wrongly find it in the override cache for C++
functions and therefor override from python wouldn't be called.
The fix is to erase the type from the override cache when the type is destroyed.
* test: Pass by const ref instead of by value (clang-tidy)
* test: Rename classes and move to different files
Rename the classes and files so they're no too generic. Also, better place to
test the stuff is in test_virtual_functions.cpp/.py as we're basically testing
the virtual functions/trampolines.
* Add TODO for erasure code

On Unix, setuptools prepends $CFLAGS and $CPPFLAGS to the compiler flags
(they always come before extra_compile_args and anything else; see
distutils.sysconfig.customize_compiler). In practice, the environment
variables are useful e.g. to quickly generate a debug build (e.g. by
setting CFLAGS=-g), but Pybind11Extension currently unconditionally
overwrites this with -g0.
Instead, check the environment variables and only insert -g0 if not
overridden by them.

Two of the four cpp_function overloads are missing std::forward calls, which seems like a simple oversight.
