Type varlinkapi.VarlinkCall currently only used as receiver for
RequiresUpgrade() future helpers could be added to this type.
RequiresUpgrade() verifies caller has given correct options to the call
for the given operation.

StartAndAttach() runs start() in a goroutine, which can allow it
to fire after the caller returns - and thus, after the defer to
unlock the container lock has fired.
The start() call _must_ occur while the container is locked, or
else state inconsistencies may occur.

Adding the journald configuration broke decoding the default
libpod.conf, because it was after the [runtimes] table (and was
being interpreted as a member of the table, and not the larger
config). We can't easily fix this on the TOML side, so our best
bet is to move it above the table and add a comment to try and
make sure this doesn't happen again.

We want the remote tests for our distributions to be tested in a
different VM than the local tests. This allows for faster CI runs and
easier debug as well as seperation of flakes.

If the systemd development files are not present on the system which
builds podman, then `podman events` will error on runtime creation.
Beside this, a warning will be printed when compiling podman.
This commit mainly exists because projects which depend on libpod
would not need the podman event support and therefore do not need to
rely on the systemd headers.

We were always raising an error when the rootless user attempted to
setup resources, but this is not the case anymore with cgroup v2.

When using CGroupfs, we see races during pod removal between
removing the CGroup and the cleanup process starting (in the
CGroup, thus preventing removal).
The simplest way to avoid this is to prevent the forking of the
cleanup process. Conveniently, we can do this via the CGroup that
we already created for Conmon - we just need to update the PID
limit to 0, which completely inhibits new forks.

Buildah no longer updates the create time of single-action images
(e.g. `FROM ...` with no other instructions. This isn't a bug (it
matches Docker's behavior), but it broke one of our tests.

Instead of rewriting the logic, reuse the standard logic we use
for removing containers, which is much better tested.

Ensure that, if an error occurs somewhere along the way when we
remove a pod, it's preserved until the end and returned, even as
we continue to remove the pod.

Removing a pod must first removal all containers in the pod.
Libpod requires the state to remain consistent at all times, so
references to a deleted pod must all be cleansed first.
Pods can have many containers in them. We presently iterate
through all of them, and if an error occurs trying to clean up
and remove any single container, we abort the entire operation
(but cannot recover anything already removed - pod removal is not
an atomic operation).
Because of this, if a removal error occurs partway through, we
can end up with a pod in an inconsistent state that is no longer
usable. What's worse, if the error is in the infra container, and
it's persistent, we get zombie pods - completely unable to be
removed.
When we saw some of these same issues with containers not in
pods, we modified the removal code there to aggressively purge
containers from the database, then try to clean up afterwards.
Take the same approach here, and make cleanup errors nonfatal.
Once we've gone ahead and removed containers, we need to see
pod deletion through to the end - we'll log errors but keep
going.
Also, fix some other small things (most notably, we didn't make
events for the containers removed).
