When the service is running with trace log level it wraps the
`http.ResponseWriter` to log extra information. The problem is that the
new type does not keep all the functions from the embedded type.
Instead we have to implement them ourselves, however only Write() was
implemented. Thus `Hijack()`could not be called on the writer. To
prevent these issues we would implement all the interfaces that the
inner type supports (Header, WriteHeader, Flush, Hijack).

The goal of the wait_for_port() function is to return when the port is
bound. This is to make sure we wait for application startup time.
This can be seen in some comments of the callers.
Commit 7e3d04fb caused this regression while reworking the logic to read
ports from /proc. I doesn't seem to cause problems in CI, properly
because the function returns before the port is bound.
I have not seen any flakes related to this but I only see the ones on
PRs where I rerun tests so it is best to wait for Ed to take a look.
Also fixes the broken ipv4_to_procfs() which only passes one argument to
__ipv4_to_procfs(), this results in the ipv4 not beeing inverted.
Therefore all bind checks against a direct ipv4 did not work.
This function accepts only an ipv4 but one caller passes localhost
which is invalid.

On cgroup v1 we need to mount only the systemd named hierarchy as
writeable, so we configure the OCI runtime to mount /sys/fs/cgroup as
read-only and on top of that bind mount /sys/fs/cgroup/systemd.
But when we use a private cgroupns, we cannot do that since we don't
know the final cgroup path.
Also, do not override the mount if there is already one for
/sys/fs/cgroup/systemd.

Currently Podman prevents SELinux container separation,
when running within a container. This PR adds a new
--security-opt label=nested
When setting this option, Podman unmasks and mountsi
/sys/fs/selinux into the containers making /sys/fs/selinux
fully exposed. Secondly Podman sets the attribute
run.oci.mount_context_type=rootcontext
This attribute tells crun to mount volumes with rootcontext=MOUNTLABEL
as opposed to context=MOUNTLABEL.
With these two settings Podman inside the container is allowed to set
its own SELinux labels on tmpfs file systems mounted into its parents
container, while still being confined by SELinux. Thus you can have
nested SELinux labeling inside of a container.

This case is fixed by passt commit bad252687271 ("conf, udp: Allow
any loopback address to be used as resolver") and the fix is now
available in packages included by the CI images.
Note that, depending on the resolver on the host, we might get
1.0.0.127.in-addr.arpa resolved to localhost, or simply NXDOMAIN for
it: accept a failure on the nslookup command, as long as we have a
response for 1.0.0.127.in-addr.arpa in the output. If we have any
response, that means we could talk to the resolver.

The test should make sure the logs --follow call will log entries that
are created in the future when --since is used and doe not include the
container start event. However it seems the timing is to tight. I think
it was possible that CI logged the line before the logs call was made,
thus it is missing because --since excluded it.
I cannot reproduce so I am not 100% on this but we can reopen the issue
if it still happens.

It makes little sense to create a log line string from the entry just to
parse it again into a LogLine. We have the typed fields so we can
assemble the logLine direclty, this makes things simpler and more
efficient.
Also entries from the passthrough driver do not use the CONTAINER_ID_FULL
field, instead we can just access c.ID() directly.

The passthrough driver is designed for use in systemd units. By default
we can expect systemd to log the output on journald unless the unit sets
differen StandardOutput/StandardError settings.
At the moment podman logs just errors out when the passthrough driver is
used. With this change we will read the journald for the unit messages.
The logic is actually very similar to the existing one, we just need to
change the filter. We now filter by SYSTEMD_UNIT wich equals to the
contianer cgroup, this allows us the actually filter on a per contianer
basis even when multiple contianers are started in the same unit, i.e.
via podman-kube@.service.
The only difference a user will see is that journald will merge
stdout/err into one stream so we loose the separation there.

Support auto updating containers running inside pods. Similar to
containers, the systemd units need to be generated via
`podman-generate-systemd --new $POD` to generate the pod's units.
Note that auto updating a container inside a pod will restart the entire
pod. Updates of multiple containers inside a pod are batched, such that
a pod is restarted at most once. That is effectively the same mechanism
for auto updating containers in a K8s YAML via the `podman-kube@`
template or via Quadlet.
Updating a single container unit without restarting the entire pod is
not possible. The reasoning behind is that pods are created with
--exit-policy=stop which will render the pod to be stopped when auto
updating the only container inside the pod. The (reverse) dependencies
between the pod and its containers unit have been carefully selected for
robustness. Changes may entail undesired side effects or backward
incompatibilities that I am not comfortable with.

...safer, too: the big change is using 'mapfile' to split
multiline strings; this preserves empty lines, making it
easy to see spurious (or missing) blank lines in output.
Another change is to indent the expected-output string
consistently, for readability.
Then, to handle \r (CR) and other control characters, use
bash %q to format special chars. But %q makes\ it\ hard\ to
read\ lines\ with\ spaces, so strip off those backslashes.
This makes assert() much larger and uglier, but this is
code that shouldn't be touched often.
Finally, because these are big changes to critical code,
write a complicated regression test suite for assert().
