This changes libstdc++ to use the 'black' Python formatter. This
formatter is somewhat standard and fairly comprehensive. FWIW we use
this in gdb, mainly because it means we don't have to review Python
code for formatting style.
This patch also runs 'isort', which handles sorting the imports.
A new pyproject.tom file is added, so after this you can:
cd .../libstdc++/python
black .
isort .
... and have any changes reformatted.
libstdc++-v3/ChangeLog:
* pyproject.toml: New file.
* python/libstdcxx/v6/printers.py: Reformat.
* python/libstdcxx/v6/xmethods.py: Reformat.
* python/libstdcxx/v6/__init__.py: Reformat.
