A few new annoyances. Of note is the new warning for an unspecified
encoding when opening a text file, which actually does indicate a
potentially real problem; see
https://www.python.org/dev/peps/pep-0597/#motivation
Use LC_CTYPE to determine an encoding to use for interpreting QEMU's
terminal output. Note that Python states: "language code and encoding
may be None if their values cannot be determined" -- use a platform
default as a backup.
Notes: Passing encoding=None will generate a suppressed warning on
Python 3.10+ that 'None' should not be passed as the encoding
argument. This behavior may be deprecated in the future and the default
switched to be a ubiquitous UTF-8. Opting in to the locale default will
be done by passing the encoding 'locale', but that isn't available in
3.6 through 3.9. Presumably this warning will be unsuppressed some time
prior to the actual switch and we can re-investigate these issues at
that time if necessary.

We often call qmp() with unpacking dict, like qmp('foo', **{...}).
mypy don't really like it, it thinks that passed unpacked dict is a
positional argument and complains that it type should be bool (because
second argument of qmp() is conv_keys: bool).
Allow passing dict directly, simplifying interface, and giving a way to
satisfy mypy.

Pylint prior to 2.8.3 (We pin at >= 2.8.0) includes function and method
signatures as part of its duplicate checking algorithm. This check does
not listen to pragmas, so the only way to disable it is to turn it off
completely or increase the minimum duplicate lines so that it doesn't
trigger for functions with long, multi-line signatures.
When we decide to upgrade to pylint 2.8.3 or greater, we will be able to
use 'ignore-signatures = true' to the config instead.
I'd prefer not to keep us on the very bleeding edge of pylint if I can
help it -- 2.8.3 came out only three days ago at time of writing.

Also add a new _qmp_timer field to the QEMUMachine class.
Let's change the default socket timeout to None, so that if
a subclass needs to add a timer, it can be done by modifying
this private field.
At the same time, restore the timer to be 15 seconds in iotests.py, to
give an upper bound to the QMP monitor test command execution.

Currently tox tests against the installed interpreters, however if any
supported interpreter is absent then it will return fail. It seems not
reasonable to expect developers to have all supported interpreters
installed on their systems. Luckily tox can be configured to skip
missing interpreters.
This changed the tox setup so that missing interpreters are skipped by
default. On the CI, however, we still want to enforce it tests
against all supported. This way on CI the
--skip-missing-interpreters=false option is passed to tox.

Logs can be very important to debug issues, and currently QEMUMachine
instances will remove logs that are created under the temporary
directories.
With this change, the stdout and stderr generated by the QEMU process
started by QEMUMachine will always be kept along the test results
directory.

This patch *doesn't* update all of the docstring standards across the
QEMU package directory to make our docstring usage consistent. It
*doesn't* fix the formatting to make it look pretty or reasonable in
generated output. It *does* fix a few small instances where Sphinx would
emit a build warning because of malformed ReST -- If we built our Python
docs with Sphinx.

For reasons that at-present escape me, pipenv insists on creating a stub
pyproject.toml file. This file is a nuisance, because its mere presence
changes the behavior of various tools.
For instance, this stub file will cause "pip install --user -e ." to
fail in spectacular fashion with misleading errors. "pip install -e ."
works okay, but for some reason pip does not support editable installs
to the user directory when using PEP517.
References:
https://github.com/pypa/pip/pull/9990https://github.com/pypa/pip/issues/7953
As outlined in ea1213b7cc, it is still too early for us to consider
moving to a PEP-517 exclusive package. We must support older
distributions, so squash the annoyance for now. (Python 3.6 shipped Dec
2016, PEP517 support showed up in pip sometime in 2019 or so.)
Add 'pyproject.toml' to the 'make clean' target, and also delete it
after every pipenv invocation issued by the Makefile.

This is a *third* way to run the Python tests. Unlike the first two
(check-pipenv, check-tox), this version does not require any specific
interpreter version -- making it a lot easier to tell people to run it
as a quick smoketest prior to submission to GitLab CI.
Summary:
Checked via GitLab CI:
- check-pipenv: tests our oldest python & dependencies
- check-tox: tests newest dependencies on all non-EOL python versions
Executed only incidentally:
- check-dev: tests newest dependencies on whichever python version
('make check' does not set up any environment at all, it just runs the
tests in your current environment. All four invocations perform the
exact same tests, just in different execution environments.)

specifier at the top into its component pieces and move them near the
targets they describe so that they're much harder to forget to update.

Move it up near the check-pipenv help text, and update it to suggest parity.
(At the time I first added it, I wasn't sure if I would be keeping it,
but I've come to appreciate it as it has actually helped uncover bugs I
would not have noticed without it. It should stay.)

Well, Cleber was right, this is a better name.
In preparation for adding a different kind of virtual environment check
(One that simply uses whichever version of Python you happen to have),
rename this test 'check-pipenv' so that it matches the CI job
'check-python-pipenv'.
Remove the "If you don't know which test to run" hint, because it's not
actually likely you have Python 3.6 installed to be able to run the
test. It's still the test I'd most prefer you to run, but it's not the
test you are most likely to be able to run.
Rename the 'venv' target to 'pipenv' as well, and move the more
pertinent help text under the 'check-pipenv' target.
