Many dependencies started using go 1.22 which means we have to follow in
order to update.
Disable the now depracted exportloopref linter as it was replaced by
copyloopvar as go fixed the loop copy problem in 1.22[1]
Another new chnage in go 1.22 is the for loop syntax over ints, the
intrange linter chacks for this but there a lot of loops that have to be
converted so I didn't do it here and disable th elinter for now, th eold
syntax is still fine.

This commit vendor pre-release version of `c/common:8483ef6022b4`.
It also adapts the code to the new `c/common/libimage` API, which
fixes an image listing race that was listing false warnings.

The podman container cleanup process runs asynchronous and by the time
it gets the lock it is possible another podman process already did the
cleanup and then did a new init() to start it again. If the cleanup
process gets the lock there it will cause very weird things.
This can be observed in the remote start API as CI flakes.

This started off as an attempt to make `podman stop` on a
container started with `--rm` actually remove the container,
instead of just cleaning it up and waiting for the cleanup
process to finish the removal.
In the process, I realized that `podman run --rmi` was rather
broken. It was only done as part of the Podman CLI, not the
cleanup process (meaning it only worked with attached containers)
and the way it was wired meant that I was fairly confident that
it wouldn't work if I did a `podman stop` on an attached
container run with `--rmi`. I rewired it to use the same
mechanism that `podman run --rm` uses, so it should be a lot more
durable now, and I also wired it into `podman inspect` so you can
tell that a container will remove its image.
Tests have been added for the changes to `podman run --rmi`. No
tests for `stop` on a `run --rm` container as that would be racy.

The new golangci-lint version 1.60.1 has problems with typecheck when
linting remote files. We have certain pakcages that should never be
inlcuded in remote but the typecheck tries to compile all of them but
this never works and it seems to ignore the exclude files we gave it.
To fix this the proper way is to mark all packages we only use locally
with !remote tags. This is a bit ugly but more correct. I also moved the
DecodeChanges() code around as it is called from the client so the
handles package which should only be remote doesn't really fit anyway.

When we create a container we first create it in the storage then in the
libpod db so there is a tiny window where it is seen as storage ctr but
then by the time we mount it we see it was a libpod container.

When the cidfile does not exists and ignore is set the cli parser skips
the file without error and we call into the backend code without any
names at all. This should logically be a NOP but on remote it caused all
containers to be returned which caused podman stop to stop everything in
this case.

The podman container cleanup command is not really intended for human
use. Instead each conmon will spawn this command after the container
exit to make sure we can cleanup resources asynchronously. However this
command will always race against other foreground process such as podman
rm -fa. Therefore it is possible that the ctr was already removed and we
should not log errors in this case.
While these errors are normally not seen as the command is int he
background you can see it if you enable syslog logging and then they
just spam the log with useless errors so just ignore them.

The current code did something like this:
lock()
getState()
unlock()
if state != running
lock()
getState() == running -> error
unlock()
This of course is wrong because between the first unlock() and second
lock() call another process could have modified the state. This meant
that sometimes you would get a weird error on start because the internal
setup errored as the container was already running.
In general any state check without holding the lock is incorrect and
will result in race conditions. As such refactor the code to combine
both StartAndAttach and Attach() into one function that can handle both.
With that we can move the running check into the locked code.
Also use typed error for this specific error case then the callers can
check and ignore the specific error when needed. This also allows us to
fix races in the compat API that did a similar racy state check.
This commit changes slightly how we output the result, previously a
start on already running container would never print the id/name of the
container which is confusing and sort of breaks idempotence. Now it will
include the output except when --all is used. Then it only reports the
ids that were actually started.

The code currently tried to avoid joining the userns from conmon
directly and rather joined to only read the pid file and then send this
back to use so we could join the userns. From the comment this was done
because we could not read the pid file. However this is no longer true
as of commit 49eb5af301 and file is no always owned by the real user.
This means we can just remove this special logic and join the namespace
directly there. A test has been added to check the rejoin logic with a
custom uidmapping.

When a user specifies a invalid connection in CONTAINER_CONNECTION then
podman should return a proper error saying so. Currently it ignored the
error and in rootFlags() just exited early with defining any flags. This
caused a panic then when trying to use the flags later.
In order to address this first store the connection error in the
PodmanConfig struct and not abort right away during flag setup. This is
important as the user might have specified a flag with a valid remote
connection. As such we check all flags and only when none were given we
return the connection error.
Also while at it I noticed that the default connection reported via
podman --help was wrong as it only used the old containers.conf field
for it and did not consider the podman-connections.json default.
New regression tests have been added to make sure it behaves correctly.
This fixes the problem reported in the PR #22997.

is marked as experimental in c/storage.

Effectively, this is an ability to take an image already pulled
to the system, and automatically mount it into one or more
containers defined in Kubernetes YAML accepted by `podman play`.
Requirements:
- The image must already exist in storage.
- The image must have at least 1 volume directive.
- The path given by the volume directive will be mounted from the
image into the container. For example, an image with a volume
at `/test/test_dir` will have `/test/test_dir` in the image
mounted to `/test/test_dir` in the container.
- Multiple images can be specified. If multiple images have a
volume at a specific path, the last image specified trumps.
- The images are always mounted read-only.
- Images to mount are defined in the annotation
"io.podman.annotations.kube.image.automount/$ctrname" as a
semicolon-separated list. They are mounted into a single
container in the pod, not the whole pod.
As we're using a nonstandard annotation, this is Podman only, any
Kubernetes install will just ignore this.
Underneath, this compiles down to an image volume
(`podman run --mount type=image,...`) with subpaths to specify
what bits we want to mount into the container.

Commit 668d517af9 moved a lot of type definitions and by that also
copied a bucnh of swagger:model comments, this caused swagger to create
a incorrect yaml that can no longer be parsed by redoc due
"Self-referencing circular pointer".
The yaml basically defined the type with a name and the pointed to the
same name definition again so it caused a infinitive recursion where
redoc just throws an error but the swagger style ignored the case so it
seemed like it worked but obviously the type information was not
working.

This was added ages ago in commit c65b3599cc, however in the meantime
both podman and conmon can support longer socket paths as they use a

Thus this restriction is not needed anymore and we can drop a workaround
