Upgrade from Qt5 to Qt6 in our CI runners and dev environments, since
the latest PySide6 versions do not support Qt5. This leaves only our
Debian / Fedora packages relying on Qt5, since there's no PySide6
package for them yet.
There are some caveats to the Qt6 upgrade:
1. Debian Bullseye has a missing dependency to `libgl1`, so we need to
install it separately.
2. Ubuntu Jammy has a missing dependency to `libxkbcommon-x11-0`, which
we have to install separately.
3. Ubuntu Focal does not have Qt6, but surprisingly PySide6 works with
Qt5.
4. All Debian-based distros require `libxcb-cursor0`.
As a side effect, we have to make our `env.py` a bit more complicated,
to cater to these exceptions.

Pass the X11 socket of the Linux CI runners to the container where our
CI tests run, with the `-g` flag of `dev_scripts/env.py`. By having a
working X11 socket, we can run GUI tests. Prior to this fix, we would
encounter this error:
tests/gui/test_main_window.py::test_change_document_button qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: xcb, offscreen, wayland-egl, wayland, eglfs, vnc, minimalegl, vkkhrdisplay, linuxfb, minimal.
Another alternative we considered was to use the
`QT_QPA_PLATFORM=offscreen` environment variable. This alternative
works, but it's less close to the end-user's environment, so we decided
in favor of the approach above.
The Ubuntu 23.04 docker image includes a user by default (ubuntu) which
overtakes the 1000 uid and so our user becomes 1001 which makes the user
directory unwritable. The solution as suggested in [1] was to remove
that user.

The files in `container/` no longer make sense to have that name since
the "document to pixels" part will run in Qubes OS in its own virtual
machine.
To adapt to this, this PR does the following:
- Moves all the files in `container` to `dangerzone/conversion`
- Splits the old `container/dangerzone.py` into its two components
`dangerzone/conversion/{doc_to_pixels,pixels_to_pdf}.py` with a
`common.py` file for shared functions
- Moves the Dockerfile to the project root and adapts it to the new
container code location
- Updates the CircleCI config to properly cache Docker images.
- Updates our install scripts to properly build Docker images.
- Adds the new conversion module to the container image, so that it can
be imported as a package.
- Adapts the container isolation provider to use the new way of calling
the code.
NOTE: We have made zero changes to the conversion code in this commit,
except for necessary imports in order to factor out some common parts.
Any changes necessary for Qubes integration follow in the subsequent
commits.
Fix transient errors in Debian Bullseye CI tests by using a different
machine image (Ubuntu 22.04 vs Ubuntu 20.04), and solving some Podman
config issues along the way.

Pave the way for deploying .deb and .rpm packages to
packages.freedom.press. Remove the code that deploys to PackageCloud
once we tag a commit with `v<semver>`.

We no longer need to install Poetry via PyPI, since the upstream Debian
issues have been fixed. Moreover, PEP 668 [1] is now enforced in Debian
Bookworm, so we can't install Poetry globally via `pip` in any case.
For these reasons, prefer installing Poetry via APT.

Add libqt5gui5 as a test dependency in the 'convert-test-docs' step.
This package brings several other Qt and graphics libraries, which are
the ones that we actually require to run the tests *with PySide6*. Else,
we encounter this error:
```
Traceback (most recent call last):
File "/home/circleci/project/dangerzone/gui/__init__.py", line 19, in <module>
from PySide6 import QtCore, QtGui, QtWidgets
ImportError: libEGL.so.1: cannot open shared object file: No such file or directory
```
Note that the same package is not required when importing PySide2.QtGui,
which is why we hadn't encountered this issue before. Also, in the rest
of our environments, we explicitly install libqt5gui5, in order to run
the Dangerzone GUI.
Narrow down the system packages that we install in dev environments. The
rationale is that we get most of the Python dependencies from Poetry, so
we don't need to install them from the system as well.
The packages that we do need to install are non-Python ones, and this
commit adds some that were missing: make, python3-stdeb. Also, we
explicitly install the base Qt5 libraries, in order to get the graphics
and C++ libraries that we can't get from PyPI.
Add a script that makes the user go through the QA steps for a supported
Dangerzone platform, and may optionally run them automatically, if the
user agrees.
Closes#287
Fix the failing convert-test-docs step, by pinning Poetry to version
1.2.2. This way, we avoid a bug in Poetry 1.3 [1], which was recently
released on PyPI.

Debian has removed the python-all package from its Bookworm repos, which
breaks our CI tests. Looking into why python-all is required in the
first place, we found that it's an artificial stdeb requirement [1],
prior to 0.9.1 versions
The only platform affected by this issue is Ubuntu Focal, so our
solution is to install python-all specifically for that platform.
Finally, we further simplify our build tasks [2] (on Debian-like
distros) by not letting dh-python run tests when building the packages.
Running the tests has some issues after all:
1. It requires installing all the runtime dependencies of Dangerzone,
since it uses `python -m unittest discover` underneath.
2. It doesn't aid in the stability of the package, since unittest cannot
run test cases for PyTest.

Introduce a script for installing Podman in Ubuntu Focal, in
environments that may, or may not, have sudo installed.
Also, update our CircleCI configuration to use this script when
installing Podman.
Fedora 37 had been removed (commit d7cbe41) due to lack of support by
packagecloud (our package hosting solution at the time). This will no
longer be true and thus we can add this distro to the list of supported.
