when using --userns=auto or --userns=pod, we should bind mount /sys
from the host instead of creating a new /sys in the container,
otherwise we rely on the fallback provided by crun, which might not be
available in other runtimes.
Also, in the last version of crun the fallback is stricter than it
used to be before and it uses a recursive bind mount through the new
mount API. That can be missing on old kernel.

The function which generates and assigns a random
port number for the --publish-all functionality
was not properly marking some ports as "used".
In very rare occasions this can cause a randomly
"generated" port to be used twice creating an
impossible container configuration.

As @mheon pointed out in PR #17055[^1], isVirtualConsoleDevice() does
not only matches VT device paths but also devices named like
/dev/tty0abcd.
This causes that non VT device paths named /dev/tty[0-9]+[A-Za-z]+ are
not mounted into privileged container and systemd containers accidentally.
This is an unlikely issue because the Linux kernel does not use device
paths like that.
To make it failproof and prevent issues in unlikely scenarios, change
isVirtualConsoleDevice() to exactly match ^/dev/tty[0-9]+$ paths.
Because it is not possible to match this path exactly with Glob syntax,
the path is now checked with strings.TrimPrefix() and
strconv.ParseUint().
ParseUint uses a bitsize of 16, this is sufficient because the max
number of TTY devices is 512 in Linux 6.1.5.
(Checked via 'git grep -e '#define' --and -e 'TTY_MINORS').
The commit also adds a unit-test for isVirtualConsoleDevice().

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.
