- Line length should be < 80
- You shouldn't perform unscoped imports except at the top of the module
Notably, the sys.path hack creates problems with the import rule. This
will be fixed later.

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.

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.

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.

Redirect to the new qom scripts. These forwarders can be deleted
eventually when there has been more time for the dust on the Python
packaging to settle and people understand how to find these commands.
Note: You can run these by setting $PYTHONPATH in your shell and then
running "python3 -m qemu.qmp.qom", or you can install the qemu namespace
package and use the "qom" or "qom-set" scripts.
I've written how to install the package elsewhere, but for the sake of
git-blame, cd to ./python, and then do:
- pip3 install [--user] [-e] .
--user will install to your local user install (will not work inside of
a venv), omitting this flag installs to your system-wide packages
(outside of a venv) or to your current virtual environment (inside the
venv).
When installing to a venv or to your system-wide packages, "qom"
should be in your $PATH already. If you do a user install, you may
need to add ~/.local/bin to your $PATH if you haven't already.
-e installs in editable mode: the installed package is effectively just
a symlink to this folder; so changes to your git working tree are
reflected in the installed package.
Note: installing these packages to an environment outside a venv can be
dangerous: Many QEMU scripts will begin to prefer the installed version
instead of the version directly in the tree. Use with caution. editable
mode is recommended when working outside of a venv.

This takes the place of qmp-shell's __get_address function. It also
allows other utilities to share the same parser and syntax for
specifying QMP locations.

This script has not seen a patch that was specifically for this script
since it was moved to this location in 2013, and I doubt it is used. It
uses "man qmp" for its help message, which does not exist. It also
presumes there is a manual page for qmp-XXX, for each defined qmp
command XXX. I don't think that's true.
The format it expects arguments in is something like:
block-dirty-bitmap-add --node=foo --name=bar
and has no capacity to support nested JSON arguments, either.
Most developers use either qmp-shell or socat (or pasting JSON directly
into qmp stdio), so this duplication and additional alternate syntax is
not helpful.
Remove it. Leave a breadcrumb script just in case, to be removed next
release cycle.

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.

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.
