For some very specific use cases (ex: debuggers), it can be interesting to access the internal API of CPython. I propose to install the internal API: Include/internal/*.h header files.
Attached PR implements this idea.

Example of debuggers: vmprof or faulthandler (now part of the stdlib).

bpo-35296: make install now installs the internal API (GH-10665)

I decided to merge my PR because I started to *remove* functions from the public C API to move them to the CPython internal API: _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() are two examples from bpo-35081. So some people might want even more to use the internal API. The main issue with this API is the requirement to use the same compiler with the same compilation options, especially to access atomic variables.

I reopen the issue since I'm now also interested to make the change in Python 3.7. I wrote PR 10897.
