move python/qemu/*.py to python/qemu/[machine, qmp, utils]/*.py and
update import directives across the tree.
This is done to create a PEP420 namespace package, in which we may
create subpackages. To do this, the namespace directory ("qemu") should
not have any modules in it. Those files will go into new 'machine',
'qmp' and 'utils' subpackages instead.
Implement machine/__init__.py making the top-level classes and functions
from its various modules available directly inside the package. Change
qmp.py to qmp/__init__.py similarly, such that all of the useful QMP
library classes are available directly from "qemu.qmp" instead of
"qemu.qmp.qmp".

Each instance of qemu.machine.QEMUMachine currently has a "test
directory", which may not have any relation to a "test", and it's
really a temporary directory.
Users instantiating the QEMUMachine class will be able to set the
location of the directory that will *contain* the QEMUMachine unique
temporary directory, so that parameter name has been changed from
test_dir to base_temp_dir.
A property has been added to allow users to access it without using
private attributes, and with that, the directory is created on first
use of the property.

Python test scripts that use unittest consist of multiple tests.
unittest.main allows selecting which tests to run, but currently this
is not possible because the iotests wrapper ignores sys.argv.
unittest.main command line options also allow the user to pick the
desired options for verbosity, failfast mode, etc. While "-d" is
currently translated to "-v", it also enables extra debug output,
and other options are not available at all.
These command line options only work if the unittest.main testRunner
argument is a type, rather than a TestRunner instance. Therefore, pass
the class name and "verbosity" argument to unittest.main, and adjust for
the different default warnings between TextTestRunner and unittest.main.

the machine is a s390-ccw-virtio and to select virtio-*-ccw rather

There are a couple of environment variables that we fetch with
os.environ.get() without supplying a default. Clearly they are required
and expected to be set by the ./check script (as evidenced by
execute_setup_common(), which checks for test_dir and
qemu_default_machine to be set, and aborts if they are not).
Using .get() this way has the disadvantage of returning an Optional[str]
type, which mypy will complain about when tests just assume these values
to be str.
Use [] instead, which raises a KeyError for environment variables that
are not set. When this exception is raised, catch it and move the abort
code from execute_setup_common() there.
Drop the 'assert iotests.sock_dir is not None' from iotest 300, because
that sort of thing is precisely what this patch wants to prevent.

mypy wants to ensure there's consistency between the kwargs arguments
types and any unspecified keyword arguments. In this case, conv_keys is
a bool, but the remaining keys are Any type. Mypy (correctly) infers the
**kwargs type to be **Dict[str, str], which is not compatible with
conv_keys: bool.
Because QMP typing is a little fraught right now anyway, re-type kwargs
to Dict[str, Any] which has the benefit of silencing this check right
now.
A future re-design might type these more aggressively, but this will
give us a baseline to work from with minimal disruption.

We can turn logging on/off globally instead of per-function.
Remove use_log from run_job, and use python logging to turn on
diffable output when we run through a script entry point.
iotest 245 changes output order due to buffering reasons.
An extended note on python logging:
A NullHandler is added to `qemu.iotests` to stop output from being
generated if this code is used as a library without configuring logging.
A NullHandler is only needed at the root, so a duplicate handler is not
needed for `qemu.iotests.diff_io`.
When logging is not configured, messages at the 'WARNING' levels or
above are printed with default settings. The NullHandler stops this from
occurring, which is considered good hygiene for code used as a library.
See https://docs.python.org/3/howto/logging.html#library-config
When logging is actually enabled (always at the behest of an explicit
call by a client script), a root logger is implicitly created at the
root, which allows messages to propagate upwards and be handled/emitted
from the root logger with default settings.
When we want iotest logging, we attach a handler to the
qemu.iotests.diff_io logger and disable propagation to avoid possible
double-printing.
For more information on python logging infrastructure, I highly
recommend downloading the pip package `logging_tree`, which provides
convenient visualizations of the hierarchical logging configuration
under different circumstances.
See https://pypi.org/project/logging_tree/ for more information.

Like script_main, but doesn't require a single point of entry.
Replace all existing initialization sections with this drop-in replacement.
This brings debug support to all existing script-style iotests.

Minor cleanup for HMP functions; helps with line length and consolidates
HMP helpers through one implementation function.
Although we are adding a universal toggle to turn QMP logging on or off,
many existing callers to hmp functions don't expect that output to be
logged, which causes quite a few changes in the test output.
For now, offer a use_log parameter.
Typing notes:
QMPResponse is just an alias for Dict[str, Any]. It holds no special
meanings and it is not a formal subtype of Dict[str, Any]. It is best
thought of as a lexical synonym.
We may well wish to add stricter subtypes in the future for certain
shapes of data that are not formalized as Python objects, at which point
we can simply retire the alias and allow mypy to more strictly check
usages of the name.

79 is the PEP8 recommendation. This recommendation works well for
reading patch diffs in TUI email clients.

Representing nested, recursive data structures in mypy is notoriously
difficult; the best we can reliably do right now is denote the leaf
types as "Any" while describing the general shape of the data.
Regardless, this fully annotates the log() function.
Typing notes:
TypeVar is a Type variable that can optionally be constrained by a
sequence of possible types. This variable is bound to a specific type
per-invocation, like a Generic.
log() behaves as log<Msg>() now, where the incoming type informs the
signature it expects for any filter arguments passed in. If Msg is a
str, then filter should take and return a str.
