pkg_resources has been fully dropped from modern pip/setuptools
distributions and we should phase out its use. This patch is enough to,
by itself, repair most GitLab CI tests upstream; with the exception of
tox tests which are still making use of avocado - which will be dropped
in a separate series to restore functionality there.

Python: discourage direct setup.py install

When invoking setup.py directly, the default behavior for 'install' is
to run the bdist_egg installation hook, which is ... actually deprecated
by setuptools. It doesn't seem to work quite right anymore.

By contrast, 'pip install' will invoke the bdist_wheel hook
instead. This leads to differences in behavior for the two approaches. I
advocate using pip in the documentation in this directory, but the
'setup.py' which has been used for quite a long time in the Python world
may deceptively appear to work at first glance.

Add an error message that will save a bit of time and frustration
that points the user towards using the supported installation
invocation.

python: add qemu package installer

Add setup.cfg and setup.py, necessary for installing a package via
pip. Add a ReST document (PACKAGE.rst) explaining the basics of what
this package is for and who to contact for more information. This
document will be used as the landing page for the package on PyPI.

List the subpackages we intend to package by name instead of using
find_namespace because find_namespace will naively also packages tests,
things it finds in the dist/ folder, etc. I could not figure out how to
modify this behavior; adding allow/deny lists to setuptools kept
changing the packaged hierarchy. This works, roll with it.

I am not yet using a pyproject.toml style package manifest, because
"editable" installs are not defined (yet?) by PEP-517/518.

I consider editable installs crucial for development, though they have
(apparently) always been somewhat poorly defined.

Pip now (19.2 and later) now supports editable installs for projects
using pyproject.toml manifests, but might require the use of the
--no-use-pep517 flag, which somewhat defeats the point. Full support for
setup.py-less editable installs was not introduced until pip 21.1.1:
7a95720e79

For now, while the dust settles, stick with the de-facto
setup.py/setup.cfg combination supported by setuptools. It will be worth
re-evaluating this point again in the future when our supported build
platforms all ship a fairly modern pip.
