Improve our compatibility with Docker by better handling the
state strings that we print in `podman ps`. Docker capitalizes
all states in `ps` (we do not) - fix this in our PS code. Also,
stop normalizing ContainerStateConfigured to the "Created" state,
and instead make it always be Created, with the existing Created
state becoming Initialized.
I didn't rename the actual states because I'm somewhat reticent
to make such a large change a day before we leave for break. It's
somewhat confusing that ContainerStateConfigured now returns
Created, but internally and externally we're still consistent.
[NO NEW TESTS NEEDED] existing tests should catch anything that
broke.
I also consider this a breaking change. I will flag appropriately
on Github.

When Podman is running a container in private IPC mode (default), it
creates a bind mount for /dev/shm that is then attached to a tmpfs
folder on the host file system. However, checkpointing a container has
the side-effect of stopping that container and unmount the tmpfs used
for /dev/shm. As a result, after checkpoint all files stored in the
container's /dev/shm would be lost and the container might fail to
restore from checkpoint.
To address this problem, this patch creates a tar file with the
content of /dev/shm that is included in the container checkpoint and
used to restore the container.

rootlessNetNS.Cleanup() has an issue with how it detects if cleanup

containers are first stopped and than cleanup will be called. So at one
time two containers could wait for cleanup but the second one will fail
because the first one triggered already the cleanup thus making rootless
netns unavailable for the second container resulting in an teardown
error. Instead of checking the container state we need to check the
netns state.
Secondly, podman unshare --rootless-netns should not do the cleanup.

There is a problem with creating and storing the exit command when the
container was created. It only contains the options the container was
created with but NOT the options the container is started with. One
example would be a CNI network config. If I start a container once, then
change the cni config dir with `--cni-config-dir` ans start it a second
time it will start successfully. However the exit command still contains
the wrong `--cni-config-dir` because it was not updated.
To fix this we do not want to store the exit command at all. Instead we
create it every time the conmon process for the container is startet.
This guarantees us that the container cleanup process is startet with
the correct settings.

Since we want to use the rootless cni ns also for netavark we should
pick a more generic name. The name is now "rootless network namespace"
or short "rootless netns".
The rename might cause some issues after the update but when the
all containers are restarted or the host is rebooted it should work
correctly.

We should mount the full runtime directory into the namespace instead of
just the netns dir. This allows more use cases.

The check if cleanup is needed reads all container and checks if there
are running containers with bridge networking. If we do not find any we
have to cleanup the ns. However there was a problem with this because
the state is empty by default so the running check never worked.
Fortunately the was a second check which relies on the CNI files so we
still did cleanup anyway.
With netavark I noticed that this check is broken because the CNI files
were not present.

Create a new mac address type which supports json marshal/unmarshal from
and to string. This change is backwards compatible with the previous
versions as the unmarshal method still accepts the old byte array or
base64 encoded string.

Make Podman more tolerant when parsing image volumes during container
creation and further fix an infinite loop when checking them.
Consider `VOLUME ['/etc/foo', '/etc/bar']` in a Containerfile. While
it looks correct to the human eye, the single quotes are wrong and yield
the two volumes to be `[/etc/foo,` and `/etc/bar]` in Podman and Docker.
When running the container, it'll create a directory `bar]` in `/etc`
and a directory `[` in `/` with two subdirectories `etc/foo,`. This
behavior is surprising to me but how Docker behaves. We may improve on
that in the future. Note that the correct way to syntax for volumes in
a Containerfile is `VOLUME /A /B /C` or `VOLUME ["/A", "/B", "/C"]`;
single quotes are not supported.
This change restores this behavior without breaking container creation
or ending up in an infinite loop.

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 OCICNI port format has one big problem: It does not support ranges.
So if a users forwards a range of 1k ports with podman run -p 1001-2000
we have to store each of the thousand ports individually as array element.
This bloats the db and makes the JSON encoding and decoding much slower.
In many places we already use a better port struct type which supports
ranges, e.g. `pkg/specgen` or the new network interface.
Because of this we have to do many runtime conversions between the two
port formats. If everything uses the new format we can skip the runtime
conversions.
This commit adds logic to replace all occurrences of the old format
with the new one. The database will automatically migrate the ports
to new format when the container config is read for the first time
after the update.
The `ParsePortMapping` function is `pkg/specgen/generate` has been
reworked to better work with the new format. The new logic is able
to deduplicate the given ports. This is necessary the ensure we
store them efficiently in the DB. The new code should also be more
performant than the old one.
To prove that the code is fast enough I added go benchmarks. Parsing
1 million ports took less than 0.5 seconds on my laptop.
Benchmark normalize PortMappings in specgen:
Please note that the 1 million ports are actually 20x 50k ranges
because we cannot have bigger ranges than 65535 ports.
