To debug a deadlock, we really want to know what lock is actually
locked, so we can figure out what is using that lock. This PR
adds support for this, using trylock to check if every lock on
the system is free or in use. Will really need to be run a few
times in quick succession to verify that it's not a transient
lock and it's actually stuck, but that's not really a big deal.

This is a nice quality-of-life change that should help to debug
situations where someone runs out of locks (usually when a bunch
of unused volumes accumulate).

Intented to fix an obscure, unlikely race condition in which (I
think) two parallel jobs called GetPort() and were assigned the
same port.
Also, add actual proper testing to two HTTP-registry tests, and
Skip a third that's a waste of cycles (filed #18768)

The current way of bind mounting the host timezone file has problems.
Because /etc/localtime in the image may exist and is a symlink under
/usr/share/zoneinfo it will overwrite the targetfile. That confuses
timezone parses especially java where this approach does not work at
all. So we end up with an link which does not reflect the actual truth.
The better way is to just change the symlink in the image like it is
done on the host. However because not all images ship tzdata we cannot
rely on that either. So now we do both, when tzdata is installed then
use the symlink and if not we keep the current way of copying the host
timezone file in the container to /etc/localtime.
Also note that we need to rebuild the systemd image to include tzdata in
order to test this as our images do not contain the tzdata by default.

"image rm concurrent" test is still failing, even after #18664:
Error: no contents in "/tmp/podman_test967723851/Dockerfile"
Probable cause: the images are built in parallel, and p.BuildImage()
writes one single Dockerfile. (This almost certainly renders the
test less effective than intended, since the generated images
might end up being identical).
Solution: write and use a uniquely-named Dockerfile

This test is intended to test concurrent removals, so don't

[NO NEW TESTS NEEDED]
@test "podman build -f test" in test/system/070-build.bats
Will test this. This was passing when run on a local system since
the remote end was using the clients path to read the Containerfile
The issue is it would not work in a podman machine since the
Containerfile would/should be a different path.

b25b330306 introduced this behaviour.
It was fine at the time because we didn't support "container update",
so the limit could not be changed at runtime. Since it is not
possible to change the memory limit at runtime, read the limit as
reported from the cgroup.
https://github.com/containers/crun/pull/1217 is required for crun.

the combination --pod and --userns is already blocked. Ignore the
PODMAN_USERNS variable when a pod is used, since it would cause to
create a new user namespace for the container.
Ideally a container should be able to do that, but its user namespace
must be a child of the pod user namespace, not a sibling. Since
nested user namespaces are not allowed in the OCI runtime specs,
disallow this case, since the end result is just confusing for the
user.

Reason: gpg tests all run with a different GNUPGHOME, and gpg-agent
does not like that, and there's no longer any way to run gpg
without the agent. So, do not run these tests in parallel, and
clean up agent after each test.

There is no reason to define the same code every time in each file, just
use global nodes. This diff should speak for itself.
CleanupSecrets()/Volume() no longer call Cleanup() directly, as the
global AfterEach node will always call Cleanup() this is no longer
necessary. If one AfterEach() node fails it will still run the others.
Also always unset the CONTAINERS_CONF env vars. This prevents people
from forgetting to unset it. And fix the special CONTAINERS_CONF logic
in the system connection tests, we do not want to preserve
CONTAINERS_CONF anyway so just remove this logic.
Ginkgo orders the BeforeEach and AfterEach nodes. They will be executed
from the outer-most defined to inner-most. This means our global
BeforeEach is always first. Only then the inner one (in the Describe()
function in each file). For AfterEach it is inverted, from the inner to
the outer.
