47430775ed python/qmp: remove pylint workaround from legacy.py
Pylint upgraded recently (2.13.z) and having a pylint: disable comment
in the middle of an argument field causes it some grief (It appears to
stop parsing when it encounters it, causing some syntax problems). Since
the duplicate line threshold was bumped up in 22305c2a08, we don't
need this workaround anymore. Drop it.

37094b6dd5 python: rename qemu.aqmp to qemu.qmp
Now that we are fully switched over to the new QMP library, move it back
over the old namespace. This is being done primarily so that we may
upload this package simply as "qemu.qmp" without introducing confusion
over whether or not "aqmp" is a new protocol or not.

The trade-off is increased confusion inside the QEMU developer
tree. Sorry!

Note: the 'private' member "_aqmp" in legacy.py also changes to "_qmp";
not out of necessity, but just to remove any traces of the "aqmp"
name.

0347c4c4cf python: move qmp utilities to python/qemu/utils
In order to upload a QMP package to PyPI, I want to remove any scripts
that I am not 100% confident I want to support upstream, beyond our
castle walls.

Move most of our QMP utilities into the utils package so we can split

bbbd9b6ec6 tests/acceptance: rename tests acceptance to tests avocado
In the discussion about renaming the `tests/acceptance` [1], the
conclusion was that the folders inside `tests` are related to the
framework running the tests and not directly related to the type of
the tests.

This changes the folder to `tests/avocado` and adjusts the MAKEFILE, the
CI related files and the documentation.

514d00df5f python/qmp: add send_fd_scm directly to QEMUMonitorProtocol
It turns out you can do this directly from Python ... and because of
this, you don't need to worry about setting the inheritability of the
fds or spawning another process.

Doing this is helpful because it allows QEMUMonitorProtocol to keep its
file descriptor and socket object as private implementation
details. /that/ is helpful in turn because it allows me to write a
compatible, alternative implementation.

d911accf0a python/qmp: clear events on get_events() call
All callers in the tree *already* clear the events after a call to
get_events(). Do it automatically instead and update callsites to remove
the manual clear call.

These semantics are quite a bit easier to emulate with async QMP, and
nobody appears to be abusing some emergent properties of what happens if
you decide not to clear them, so let's dial down to the dumber, simpler
thing.

Specifically: callers of clear() right after a call to get_events() are
more likely expressing their desire to not see any events they just
retrieved, whereas callers of clear_events() not in relation to a recent
call to pull_event/get_events are likely expressing their desire to
simply drop *all* pending events straight onto the floor. In the sync
world, this is safe enough; in the async world it's nearly impossible to
promise that nothing happens between getting and clearing the
events.

Making the retrieval also clear the queue is vastly simpler.

7f17908263 python: expose typing information via PEP 561
https://www.python.org/dev/peps/pep-0561/#specification

Create 'py.typed' files in each subpackage that indicate to mypy that
this is a typed module, so that users of any of these packages can use
mypy to check their code as well.

Note: Theoretically it's possible to ditch MANIFEST.in in favor of using
package_data in setup.cfg, but I genuinely could not figure out how to
get it to include things from the *source root* into the *package root*;
only how to include things from each subpackage. I tried!

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".
