Ralf W. Grosse-Kunstleve 6d1b197b46 Splitting out pybind11/stl/filesystem.h. (#3077) ... * 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.		2021-07-08 09:02:48 -07:00
