[PATCH v5 05/25] python: add qemu package installer

From: John Snow
Subject: [PATCH v5 05/25] python: add qemu package installer
Date: Thu, 18 Feb 2021 14:27:13 -0500

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.

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.

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.

Additional reading on this matter:

+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.
+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.
+This package is maintained by John Snow <jsnow@redhat.com> as part of
+the QEMU source tree. Contributions are welcome and follow the `QEMU
+patch submission process
+<https://wiki.qemu.org/Contribute/SubmitAPatch>`_, which involves
+sending patches to the QEMU development mailing list.
+John maintains a `GitLab staging branch
+<https://gitlab.com/jsnow/qemu/-/tree/python>`_, and there is an
+official `GitLab mirror <https://gitlab.com/qemu-project/qemu>`_.
+Please report bugs by sending a mail to qemu-devel@nongnu.org and CC
