Still an unknown number remains but I am running out of patience.
Adding dots is not the best use of my time.

When running podman inside systemd user units, it is possible that
systemd kills the rootless netns slirp4netns process because it was
started in the default unit cgroup. When the unit is stopped all
processes in that cgroup are killed. Since the slirp4netns process is
run once for all containers it should not be killed. To make sure
systemd will not kill the process we move it to the user.slice.
Fixes#13153

machinectl does not propogate error messages and adds extra lines in the output, exec.Cmd is able to clear the env besides PATH and TERM,
and use the given UID and GID to execute the command properly.
machinectl is still used to create a user session. Ubuntu support is limited by this.

Podman image scp should never enter the Podman UserNS unless it needs to. This allows for
a sudo exec.Command to transfer images to and from rootful storage. If this command is run using sudo,
the simple sudo podman save/load does not work, machinectl/su is necessary here.
This modification allows for both rootful and rootless transfers, and an overall change of scp to be
more of a wrapper function for different load and save calls as well as the ssh component

Instead of using math/rand we can use crypto/rand which we do not have
to seed. crypto/rand uses getrandom(2)
Also instead of adding an int to the scope name we add a 4 byte hex
string.

Otherwise, we'll always get the same sequence of random numbers which
may lead to conflicts. Also bump the number of maximum attempts to 10
instead of 3.
[NO NEW TESTS NEEDED] as I cannot enforce random number collisions.
Existing tests should continue be green and flake slightly less.

We should not modify the XDG_RUNTIME_DIR env value during runtime of
libpod, this can cause hard to find bugs. Only set it for the OCI
runtime, this matches the other commands such as start, stop, kill...

we try hard to re-use the existing podman-pause.scope name when it
already exists, causing any sort of race errors when the already
existing scope is terminating.
There is no such a requirement though, so just try with a random
name.

commit 6b3b0a17c6 introduced a check for
the PID file before attempting to move the PID to a new scope.
This is still vulnerable to TOCTOU race condition though, since the
PID file or the PID can be removed/killed after the check was
successful but before it was used.

The define package under Libpod is intended to be an extremely
minimal package, including constants and very little else.
However, as a result of some legacy code, it was dragging in all
of libpod/image (and, less significantly, the util package).
Fortunately, this was just to ensure that error constants were
not duplicating, and there's nothing preventing us from
importing in the other direction and keeping libpod/define free
of dependencies.

At present, when manually detaching from an attached container
(using the detach hotkeys, default C-p C-q), Podman will still
wait for the container to exit to obtain its exit code (so we can
set Podman's exit code to match). This is correct in the case
where attach finished because the container exited, but very
wrong for the manual detach case.
As a result of this, we can no longer guarantee that the cleanup
and --rm functions will fire at the end of 'podman run' - we may
be exiting before we get that far. Cleanup is easy enough - we
swap to unconditionally using the cleanup processes we've used
for detached and rootless containers all along. To duplicate --rm
we need to also teach 'podman cleanup' to optionally remove
containers instead of cleaning them up.
(There is an argument for just using 'podman rm' instead of
'podman cleanup --rm', but cleanup does have different semantics
given that we only ever expect it to run when the container has
just exited. I think it might be useful to keep the two separate
for things like 'podman events'...)

Execute the command as described by a container image. The value of the label is processed
into a command by:
1. Ensuring the first argument of the command is podman.
2. Substituting any variables with those defined by the environment or otherwise.
If no label exists in the container image, nothing is done.
