[PATCH v4 0/9] improvement to Python detection, preparation for dropping 3.6

[Paolo Bonzini]

This is my take on John's patches to improve Python detection and to
prepare for dropping Python 3.6 support.

The main change with respect to John's work is that lcitool is updated
and the container images for CI can install Sphinx via pip; this
way documentation is still built on the CentOS 8 jobs.

A smaller change is that patch "configure: Look for auxiliary Python
installations" will only look at the $PYTHON variable if it is set,
without falling back to a PATH search.

This series includes the final patch to drop support for Python 3.6,
but it makes sense even without it.
