First, make podman diff accept optionally a second argument. This allows
the user to specify a second image/container to compare the first with.
If it is not set the parent layer will be used as before.
Second, podman container diff should only use containers and podman
image diff should only use images. Previously, podman container diff
would use the image when both an image and container with this name
exists.
To make this work two new parameters have been added to the api. If they
are not used the previous behaviour is used. The same applies to the
bindings.

Added logic and handling for two new Podman pod create Flags.
--cpus specifies the total number of cores on which the pod can execute, this
is a combination of the period and quota for the CPU.
--cpuset-cpus is a string value which determines of these available cores,
how many we will truly execute on.

Much to my regret, there is a number of images in the wild with invalid
platforms breaking the platform checks in libimage that want to make
sure that a local image is matching the expected platform.
Imagine a `podman run --arch=arm64 fedora` with a local amd64 fedora
image. We really shouldn't use the local one in this case and pull down
the arm64 one.
The strict platform checks in libimage in combination with invalid
platforms in images surfaced in Podman being able to pull an image but
failing to look it up in subsequent presence checks. A `podman run`
would hence pull such an image but fail to create the container.
Support images with invalid platforms by vendoring the latest HEAD from
containers/common. Also remove the partially implemented pull-policy
logic from Podman and let libimage handle that entirely. However,
whenever --arch, --os or --platform are specified, the pull policy will
be forced to "newer". This way, we pessimistically assume that the
local image has an invalid platform and we reach out to the registry.
If there's a newer image (i.e., one with a different digest), we'll pull
it down.
Please note that most of the logic has either already been implemented
in libimage or been moved down which allows for removing some clutter
from Podman.
[NO TESTS NEEDED] since c/common has new tests. Podman can rely on the
existing tests.

The checkpoint archive compression was hardcoded to `archive.Gzip`.
There have been requests to make the used compression algorithm
selectable. There was especially the request to not compress the
checkpoint archive to be able to create faster checkpoints when not
compressing it.
This also changes the default from `gzip` to `zstd`. This change should
not break anything as the restore code path automatically handles
whatever compression the user provides during restore.

Restored containers, until now, had the same port mappings as the
original started container. This commit adds the parameter '--publish'
to 'podman container restore' with the same semantic as during
create/run.
With this change it is possible to create a copy from a container with a
'--publish' rule and replace the original '--publish' setting with a new
one.
# podman run -p 2345:8080 container
# podman container checkpoint -l --export=dump.tar
# podman container restore -p 5432:8080 --import=dump.tar
The restored container will now listen on localhost:5432 instead of
localhost:2345 as the original created container.

* Use cobra.Annotations to set supported EngineMode. This simplies

* Combined aliased commands into one file

Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.
Note that I tried to leave bread crumbs for changed tests.
Miscellaneous changes:
* Some errors yield different messages which required to alter some
tests.
* I fixed some pre-existing issues in the code. Others were marked as
`//TODO`s to prevent the PR from exploding.
* The `NamesHistory` of an image is returned as is from the storage.
Previously, we did some filtering which I think is undesirable.
Instead we should return the data as stored in the storage.
* Touched handlers use the ABI interfaces where possible.
* Local image resolution: previously Podman would match "foo" on
"myfoo". This behaviour has been changed and Podman will now
only match on repository boundaries such that "foo" would match
"my/foo" but not "myfoo". I consider the old behaviour to be a
bug, at the very least an exotic corner case.
* Futhermore, "foo:none" does *not* resolve to a local image "foo"
without tag anymore. It's a hill I am (almost) willing to die on.
* `image prune` prints the IDs of pruned images. Previously, in some
cases, the names were printed instead. The API clearly states ID,
so we should stick to it.
* Compat endpoint image removal with _force_ deletes the entire not
only the specified tag.

The --format flags accepts go template strings. I use this often but I
consistently forget the field names. This commit adds a way to provide
shell completion for the --format flag. It works by automatically
receiving the field names with the reflect package from the given
struct. This requires almost no maintenance since this ensures that we
always use the correct field names. This also works for nested structs.
```
$ podman ps --format "{{.P"
{{.Pid}} {{.PIDNS}} {{.Pod}} {{.PodName}} {{.Ports}}
```
NOTE: This only works when you use quotes otherwise the shell does not
provide completions. Also this does not work for fish at the moment.

Currently we have rootless users who want to leak their groups access
into containers, but this group access is only able to be pushed in by
a hard to find OCI Runtime annotation. This PR makes this option a lot
more visable and hides the complexity within the podman client.
This option is only really needed for local rootless users. It makes
no sense for remote clients, and probably makes little sense for
rootfull containers.

If you are attempting to run a container in interactive mode, and want
a --tty, then there must be a terminal in use.
Docker exits right away when a user specifies to use a --interactive and
--TTY but the stdin is not a tty.
Currently podman will pull the image and then fail much later.
Podman will continue to run but will print an warning message.

Copy is full of perils. Some of them are the nuances when copying
directories. Who would have thought that
* cp dir foo
* cp dir/ foo
* cp dir/. foo
are all supposed to yield the same result when foo does not exist.
`podman cp` now supports all three notations, which required to massage
the front-end code in `cmd/podman` a bit. The tests have been extended
and partially rewritten to test container->host and host->container
copy operations.

Traditionally, the path resolution for containers has been resolved on
the *host*; relative to the container's mount point or relative to
specified bind mounts or volumes.
While this works nicely for non-running containers, it poses a problem
for running ones. In that case, certain kinds of mounts (e.g., tmpfs)
will not resolve correctly. A tmpfs is held in memory and hence cannot
be resolved relatively to the container's mount point. A copy operation
will succeed but the data will not show up inside the container.
To support these kinds of mounts, we need to join the *running*
container's mount namespace (and PID namespace) when copying.
Note that this change implies moving the copy and stat logic into
`libpod` since we need to keep the container locked to avoid race
conditions. The immediate benefit is that all logic is now inside
`libpod`; the code isn't scattered anymore.
Further note that Docker does not support copying to tmpfs mounts.
Tests have been extended to cover *both* path resolutions for running
and created containers. New tests have been added to exercise the
tmpfs-mount case.
For the record: Some tests could be improved by using `start -a` instead
of a start-exec sequence. Unfortunately, `start -a` is flaky in the CI
which forced me to use the more expensive start-exec option.
