golint, scopelint and interfacer are deprecated. golint is replaced by
revive. This linter is better because it will also check for our error
style: `error strings should not be capitalized or end with punctuation or a newline`
scopelint is replaced by exportloopref (already endabled)
interfacer has no replacement but I do not think this linter is
important.

There is no reason to mark them directly as deprecated since we still
have to use them as long as we want to support 3.X calls. The
staticcheck linter is complaining about the Deprecated comment but that
doesn't make sense in this context. There is no good way to only exclude
a single check with golangci-lint.
I renamed the function with a V3 suffix to make clear that we only use
this for backwards compat.

activation.Listeners() can return an net.Listener array which contains
nil entries if it cannot listen on the given fds. This can cause podman
to panic so we should check the we have non nil net.Listener first.

This is an enhancement proposal for the checkpoint / restore feature of
Podman that enables container migration across multiple systems with
standard image distribution infrastructure.
A new option `--create-image <image>` has been added to the
`podman container checkpoint` command. This option tells Podman to
create a container image. This is a standard image with a single layer,
tar archive, that that contains all checkpoint files. This is similar to
the current approach with checkpoint `--export`/`--import`.
This image can be pushed to a container registry and pulled on a
different system. It can also be exported locally with `podman image
save` and inspected with `podman inspect`. Inspecting the image would
display additional information about the host and the versions of
Podman, criu, crun/runc, kernel, etc.
`podman container restore` has also been extended to support image
name or ID as input.

There's a potential race condition where we attempt to attach to
a container immediately after it's been stopped, but before the
cleanup process has run on it. The existing code doesn't allow an
attach to containers in the Stopped state (cleanup process has
not run) but does allow an attach to containers in the Exited
state (cleanup process has run). This doesn't make very much
sense and there's no technical reason to restrict attach to only
Exited containers, so allow attaching to Stopped containers.
[NO NEW TESTS NEEDED] Testing this is very racy - we need to get
in before the cleanup process runs, which isn't really
deterministic when we're invoked from a script - like the CI
tests.

The PlayKube and PlayKubeDown commands accepted a "path" argument to a YAML file
to play. This requires the caller to write the YAML to a file path. The downside
of this is apparent in the HTTP handlers which have to use a temporary file on
disk to store the YAML file.
The file is opened & used as the body of the HTTP request. It's possible to
instead pass a io.Reader and use a fully in-memory request body.
Add backwards-compatible changes to bindings to allow passing either a filepath
or a io.Reader body.
Refactor the podman bindings to use a io.Reader instead of a filepath.
Simplify the HTTP handlers for PlayKube by removing the now unneeded tempfile.

When you run podman stats, the first interval always shows the wrong cpu
usage. To calculate cpu percentage we get the cpu time from the cgroup
and compare this against the system time between two stats. Since the
first time we do not have a previous stats an empty struct is used
instead. Thus we do not use the actual running time of the container but
the current unix timestamp (time since Jan 1 1970).
To fix this we make sure that the previous stats time is set to the
container start time, when it is empty.
[NO NEW TESTS NEEDED] No idea how I could create a test which would have
a predictable cpu usage.
See the linked bugzilla for a reproducer.

Add an `--ignore` flag to `podman image rm` to instruct ignoring image
if a specified image does not exist and to not throw an error. Other
commands (e.g., `podman container rm`) already support this flag.
Such an `--ignore` flag can come in handy in clean-up scripcts such as
the teardown phases in the Podman tests.

When podman generate systemd is invoked, it previously did not check if
container-prefix or pod-prefix are empty. When these are empty, the file name
starts with the separator, which is hyphen by default. This results in files
like '-containername.service'.
The code now checks if these prefixes are empty. If they are, the filename no
longer adds a separator. Instead, it uses name or ID of the container or pod.

podman container clone takes the id of an existing continer and creates a specgen from the given container's config
recreating all proper namespaces and overriding spec options like resource limits and the container name if given in the cli options
this command utilizes the common function DefineCreateFlags meaning that we can funnel as many create options as we want
into clone over time allowing the user to clone with as much or as little of the original config as they want.
container clone takes a second argument which is a new name and a third argument which is an image name to use instead of the original container's
the current supported flags are:
--destroy (remove the original container)
--name (new ctr name)
--cpus (sets cpu period and quota)
--cpuset-cpus
--cpu-period
--cpu-rt-period
--cpu-rt-runtime
--cpu-shares
--cpuset-mems
--memory
