Until Podman v4.3, privileged rootfull containers would expose all the
host devices to the container while rootless ones would exclude
`/dev/ptmx` and `/dev/tty*`.
When 5a2405ae1b ("Don't mount /dev/tty* inside privileged containers
running systemd") landed, rootfull containers started excluding all the
`/dev/tty*` devices when the container would be running in systemd
mode, reducing the disparity between rootless and rootfull containers
when running in this mode.
However, this commit regressed some legitimate use cases: exposing
non-virtual-terminal tty devices (modems, arduinos, serial
consoles, ...) to the container, and the regression was addressed in
f4c81b0aa5 ("Only prevent VTs to be mounted inside privileged
systemd containers").
This now calls into question why all tty devices were historically
prevented from being shared to the rootless non-privileged containers.
A look at the podman git history reveals that the code was introduced
as part of ba430bfe5e ("podman v2 remove bloat v2"), and obviously
was copy-pasted from some other code I couldn't find.
In any case, we can easily guess that this check was put for the same
reason 5a2405ae1b was introduced: to prevent breaking the host
environment's consoles. This also means that excluding *all* tty
devices is overbearing, and should instead be limited to just virtual
terminals like we do on the rootfull path.
This is what this commit does, thus making the rootless codepath behave
like the rootfull one when in systemd mode.
This leaves `/dev/ptmx` as the main difference between the two
codepath. Based on the blog post from the then-runC maintainer[1] and
this Red Hat bug[2], I believe that this is intentional and a needed
difference for the rootless path.

Increase the loop range from 5 to 20 to make sure we give the service
enough time to transition to inactive. Other tests have the same range
with 0.5 seconds sleeps, so I expect the new value to be sufficient and

While manually playing with --service-container, I encountered a number
of too verbose logs. For instance, there's no need to error-log when
the service-container has already been stopped.

implicitly show that #17024 is now working.

While mounting virtual console devices in a systemd container is a
recipe for disaster (I experienced it first hand), mounting serial
console devices, modems, and others should still be done by default
for privileged systemd-based containers.
v2, addressing the review from @fho:
- use backticks in the regular expression to remove backslashes
- pre-compile the regex at the package level
- drop IsVirtualTerminalDevice (not needed for a one-liner)
v3, addressing the review from @fho and @rhatdan:
- re-introduce a private function for matching the device names
- use path.Match rather than a regex not to slow down startup time
Closes#16925.

If the run errors, cobra does not execute post runs. It is a somehow
known issue (https://github.com/spf13/cobra/issues/914) but problematic
for Podmand as the runtime is shutdown during post run.
Since some commands overwrite the post run and a general lack in cobra
of post runs on errors, move the shutting down the engines directly into
Execute. Fixing the issue may fix a number of flakes.
Note that the shutdowns are NOPs for the remote client.

Do not allow for removing the service container unless all associated
pods have been removed. Previously, the service container could be
removed when all pods have exited which can lead to a number of issues.
Now, the service container is treated like an infra container and can
only be removed along with the pods.
Also make sure that a pod is unlinked from the service container once
it's being removed.

Red Hat registry is too unreliable. (As of this writing
in January 2023, quay.io is not much better, but this is
a new flake. Ubi has been flaking for a year or more).
Instead of UBI, use the new systemd-image added to system tests
in #16814. Since this reduces the number of cached images,
a few unrelated tests (image count) need to be tweaked.
And, sigh, Fedora systemd colorizes boot messages by default,
causing a failure where we don't see an expected Reached Target
message. I don't want to rely on ASCII formatting codes, so
I've updated the build-systemd-image script so it disables
systemd colors, and have built a new systemd-image:20230106.
Made a few small usability improvements to the script as well.

When you use podman logs with --until and --follow it should exit after
the requested until time and not keep hanging forever.
To make this work I reworked the code to use the better journald event
reading code for logs as well. this correctly uses the sd_journal API
without having to compare the cursors to find the EOF.
The same problems exists for the k8s-file driver, I will fix this in the
next commit.

The `containerCouldBeLogging` bool should not be false by default, when
--since is used we seek in the journal and can miss the start event so
that bool would stay false forever. This means that a running container
is not followed even when it should.
To fix this we can just set the `containerCouldBeLogging` bool based on
the current contianer state.

Reasoning
---------
When the log-driver is passthrough, the journal socket is passed to the containers as-is which has two advantages:
1. journald can see who the actual sender of the log event is,
rather than thinking everything comes from the conmon process
2. conmon will not have to copy all the log data
Code Changes
------------
If log-driver was not set by the user and service-container is set use
passthrough as the default log-driver
Update the system tests
- explicitly set logdriver in sdnotify and play tests
- podman-kube template test: Verify the default log driver for service-container
