This is a fix for errors like:

* Splitting out pybind11/stl/filesystem.h.
To solve breakages like: https://github.com/deepmind/open_spiel/runs/2999582108
Mostly following the suggestion here: https://github.com/pybind/pybind11/pull/2730#issuecomment-750507575
Except using pybind11/stl/filesystem.h instead of pybind11/stlfs.h, as decided via chat.
stl.h restored to the exact state before merging PR #2730 via:
```
git checkout 733f8de24f stl.h
```
* Properly including new stl subdirectory in pip wheel config.
This now passes interactively:
```
pytest tests/extra_python_package/
```
* iwyu cleanup.
iwyuh.py -c -std=c++17 -DPYBIND11_TEST_BOOST -Ipybind11/include -I/usr/include/python3.9 -I/usr/include/eigen3 include/pybind11/stl/filesystem.h
* Adding PYBIND11_HAS_FILESYSTEM_IS_OPTIONAL.
* Eliminating else after return.
On Windows, clang-cl does not understand /MP.
```
clang-cl: warning: argument unused during compilation: '/MP' [-Wunused-command-line-argument]

Sometimes programmers want to control this, and while it can be changed after the fact, it's commonly set via a CMAKE_ variable; if that variable is set, we should respect that (like the CMAKE_INTERPROCEDURAL_OPTIMIZATION setting).

* Fix job name
* Remove deadsnakes job for now
* Add deadsnakes jobs
* There's no deadsnakes 2.7
* Add 3.10 to versions to be discovered by legacy FindPython, and fix debug input to deadsnakes/action
* Try out branch with fix
* Update to deadsnakes/action@v2.1.1
* fix: match new extension discovery with changes to classic discovery
Followup to #2638 - this was fixed in 2.6.0, but only for classic Python
* fix: followup to avoid warnings
On very incomplete python installations (e.g. within Docker), it's
possible that distutils is not installed. In that case, the
``execute_command`` statement that queries distutils for the Python
module extension fails, and pybind11 uses the empty string. This commit
adds an extra check that causes a CMake failure with more actionable
information (just spent a lot of time trying to track down this problem :))

On some linuxes, /usr/include belongs to GCC and the standard
libraries that work with clang are in /usr/lib/clang/8.0.0 or
some variation thereof.
This results in errors such as:
```
/../lib64/gcc/x86_64-pc-linux-gnu/8.3.0/../../../../include/c++/8.3.0/bits/cxxabi_init_exception.h:38:10: fatal error: 'stddef.h' file not found
```
during extraction.
pybind11 headers passed via the `pybind11_add_module` CMake
function can now be included as `SYSTEM` includes (`-isystem`).
This allows to set stricter (or experimental) warnings in
calling projects that might throw otherwise in headers
a user of pybind11 can not influence.
This updates the compilation to always apply hidden visibility to
resolve the issues with default visibility causing problems under debug
compilations. Moreover using the cmake property makes it easier for a
caller to override if absolutely needed for some reason.
For `pybind11_add_module` we use cmake to set the property; for the
targets, we append to compilation option to non-MSVC compilers.
Currently select_cxx_standard(), which sets PYBIND11_CPP_STANDARD when
not externally set, is only called from pybind11_add_module(), but the
embed target setup (which runs unconditionally) makes use of
${PYBIND11_CPP_STANDARD}, which isn't set yet. This commit removes the
`select_cxx_standard` function completely and just always runs the
standard detection code.
This also tweaks the detection code to not bothering checking for the
`-std=c++11` flag when the `-std=c++14` detection succeeded.
./tools/check-style.sh fails on stock OS X currently; this fixes it:
- use pipes directly rather than exec redirection (macOS's ancient
version of bash fails with the latter)
- macOS's ancient bash doesn't support '\e' escapes in `echo -e`;
replace with \033 instead
- BSD grep doesn't support GREP_COLORS, but does allow GREP_COLOR.
Adding both doesn't hurt GNU grep: GREP_COLOR is deprecated, and won't
be used when GREP_COLORS is set.
- BSD grep doesn't collapse multiple /'s in the listed filename, so
failures under `include/` would should up as
`include//pybind11/whatever.h`. This removes the / from the include
directory argument.
Minor other changes:
- The CRLF detection runs with -l, so GREP_COLORS wasn't doing
anything; removed it.
- The trailing whitespace test would trigger on CRLFs, but the CR would
result in messed up output. Changed the test to just match trailing
spaces and tabs, rather than all whitespace.
At this point, there is only a single test for interpreter basics.
Apart from embedding itself, having a C++ test framework will also
benefit the C++-side features by allowing them to be tested directly.
All targets provided by pybind11:
* pybind11::module - the existing target for creating extension modules
* pybind11::embed - new target for embedding the interpreter
* pybind11::pybind11 - common "base" target (headers only)
Under MSVC we were ignoring PYBIND11_CPP_STANDARD and simply not
passing any standard (which makes MSVC default to its C++14 mode).
MSVC 2015u3 added the `/std:c++14` and `/std:c++latest` flags; the
latter, under MSVC 2017, enables some C++17 features (such as
`std::optional` and `std::variant`), so it is something we need to
start supporting under MSVC.
This makes the PYBIND11_CPP_STANDARD cmake variable work under MSVC,
defaulting it to /std:c++14 (matching the default -std=c++14 for
non-MSVC).
It also adds a new appveyor test running under MSVC 2017 with
/std:c++latest, which runs (and passes) the
`std::optional`/`std::variant` tests.
Also updated the documentation to clarify the c++ flags and add show
MSVC flag examples.
When processing many files that contain top-level items with the same
name (e.g. "operator<<"), the output was non-deterministic and depended
on the order in which the different Clang processes finished. This
commit adds sorting that also accounts for the filename to prevent
random changes from run to run.
