f12a282ff4 python/qemu: Add mypy type annotations
These should all be purely annotations with no changes in behavior at
all. You need to be in the python folder, but you should be able to
confirm that these annotations are correct (or at least self-consistent)
by running `mypy --strict qemu`.

aad3f3bb6c python/qemu: make 'args' style arguments immutable
These arguments don't need to be mutable and aren't really used as
such. Clarify their types as immutable and adjust code to match where
necessary.

In general, It's probably best not to accept a user-defined mutable
object and store it as internal object state unless there's a strong
justification for doing so. Instead, try to use generic types as input
with empty tuples as the default, and coerce to list where necessary.

652809dfa6 python/machine.py: Don't modify state in _base_args()
Don't append to the _remove_files list during _base_args; instead do so
during _launch. Rework _base_args as a @property to help facilitate
this impression.

This has the additional benefit of making the type of _console_address
easier to analyze statically.

932ca4bbde python/qemu: use isort to lay out imports
Borrowed from the QAPI cleanup series, use the same configuration to
standardize the way we write and sort imports.

0add048fbd python/qemu: fix socket.makefile() typing
Note:

A bug in typeshed (https://github.com/python/typeshed/issues/3977)
misinterprets the type of makefile(). Work around this by explicitly
stating that we are opening a text-mode file.

9b8ccd6d5b python/qemu: delint and add pylintrc
Bring our these files up to speed with pylint 2.5.0.
Add a pylintrc file to formalize which pylint subset
we are targeting.

The similarity ignore is there to suppress similarity
reports across imports, which for typing constants,
are going to trigger this report erroneously.

qtest.py do.  iotests.py needs to pass the respective path to them, and
they need to adhere to it.

976e8c5414 Replace '-machine accel=xyz' with '-accel xyz'
We've got a separate option to configure the accelerator nowadays, which
is shorter to type and the preferred way of specifying an accelerator.
Use it in the source and examples to show that it is the favored option.
(However, do not touch the places yet which also specify other machine
options or multiple accelerators - these are currently still better
handled with one single "-machine" statement instead)

abf0bf998d python/qemu: split QEMUMachine out from underneath __init__.py
It's not obvious that something named __init__.py actually houses
important code that isn't relevant to python packaging glue. Move the
QEMUMachine and related error classes out into their own module.

Adjust users to the new import location.

8f8fd9edba Introduce a Python module structure
This is a simple move of Python code that wraps common QEMU
functionality, and are used by a number of different tests
and scripts.

By treating that code as a real Python module, we can more easily:
 * reuse code
 * have a proper place for the module's own unittests
 * apply a more consistent style
 * generate documentation
