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
them out from the PyPI upload.

c89b38cd0a scripts/qom-fuse: add redirection shim to python/qemu/qmp/qom-fuse.py
By leaving the script absent for a commit, git-blame travels to the new
file instead of staying on the shim.

173d185de9 scripts/qom-fuse: move to python/qemu/qmp/qom_fuse.py
Move qom-fuse over to the python package now that it passes the
linter. Update the import paradigms so that it continues to pass in the
context of the Python package.

30ec845c59 scripts/qom-fuse: add static type hints
Because fusepy does not have type hints, add some targeted warning
suppressions.

Namely, we need to allow subclassing something of an unknown type (in
qom_fuse.py), and we need to allow missing imports (recorded against
fuse itself) because mypy will be unable to import fusepy (even when
installed) as it has no types nor type stubs available.

Note: Until now, it was possible to run invocations like 'mypy qemu/'
from ./python and have that work. However, these targeted suppressions
require that you run 'mypy -p qemu/' instead. The correct, canonical
invocation is recorded in ./python/tests/mypy.sh and all of the various
CI invocations always use this correct form.

- Use FuseOSError to signal ENOENT instead of returning it

2aa101799a scripts/qom-fuse: Convert to QOMCommand
Move qom-fuse onto the QOMCommand base established in
python/qemu/qmp/qom_common.py. The interface doesn't change
incompatibly, "qom-fuse mountpoint" still works as an invocation, and
QMP_SOCKET is still used as the environment variable.

67abc3ddea scripts/qmp/qom-fuse: Unbreak import of QEMUMonitorProtocol
Commit c7b942d7f8 "scripts/qmp: Fix shebang and imports" messed with
it for reasons I don't quite understand.  I do understand how it fails
now: it neglects to import sys.  Fix that.

It now fails because it expects an old version of module fuse.  That's
next.

c7b942d7f8 scripts/qmp: Fix shebang and imports
There's more wrong with these scripts; They are in various stages of
disrepair. That's beyond the scope of this current patchset.

This just mechanically corrects the imports and the shebangs, as part of
ensuring that the python/qemu/lib refactoring didn't break anything
needlessly.

bf20b675cc Partially revert "python: futurize -f libfuturize.fixes.fix_absolute_import"
Since commit 068cf7a44c, qmp-shell

  $ ./scripts/qmp/qmp-shell
  Traceback (most recent call last):
    File "./scripts/qmp/qmp-shell", line 70, in <module>
      from . import qmp
  ValueError: Attempted relative import in non-package

Relative imports don't work on scripts that are executed
directly, so revert the change on the scripts inside scripts/qmp.
