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: https://github.com/pypa/pip/pull/9547/commits/7a95720e796a5e56481c1cc20b6ce6249c50f357 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.

QEMU Python Tooling
===================
This package provides QEMU tooling used by the QEMU project to build,
configure, and test QEMU. It is not a fully-fledged SDK and it is subject
to change at any time.
Usage
-----
The ``qemu.qmp`` subpackage provides a library for communicating with
QMP servers. The ``qemu.machine`` subpackage offers rudimentary
facilities for launching and managing QEMU processes. Refer to each
package's documentation
(``>>> help(qemu.qmp)``, ``>>> help(qemu.machine)``)
for more information.

Optional packages necessary for running code quality analysis for this
package can be installed with the optional dependency group "devel":
``pip install qemu[devel]``.
``make develop`` can be used to install this package in editable mode
(to the current environment) *and* bring in testing dependencies in one
command.
``make check`` can be used to run the available tests.
