[bug#58587] [PATCH 00/14] Introducing pyproject-build-system.

[Marius Bakke]

This is an adaptation of Lars' work in wip-python-pep517 for 'master'.

I've implemented it as a separate build system so we can do a slow
transition, starting at the leafs.

Changes from the original branch:

* Renamed to pyproject-build-system.
* It inherits some code from python-build-system.
* Python 2 and <3.7 support removed.
* A (temporary) sanity-check-next.py file is introduced.
* A new (hidden) 'python-sans-pip' variable is introduced.
* The 'python-toolchain' package includes pip, wheel, setuptools, and
  pypa-build.

The build system logic is unchanged from Lars' branch.

I've converted a handful packages that were doing PEP 517 style builds
to the new build system with great success.  It should help a lot with
packaging "modern" Python packages.

Please try it for new packages, even those using setup.py, and don't be
afraid to report problems!

I plan to eventually merge it with python-build-system instead of
keeping it separate.  Thoughts?

Note: documentation is missing.  Will work on that next.
