When stopping the transient systemd timer/unit which powers running
health checks, make sure to ignore its dependencies. It turns out
that we're otherwise running into a timeout when running a container in
a systemd unit and reboot.
An alternative may be to further tweak some attributes/options when
creating the timer/unit via systemd-run but it seems safe to just ignore
the dependencies and stop.
[NO NEW TESTS NEEDED] - we don't yet have means to test reboots.

The podman healthchecks are implemented using systemd timers, this works
great but it will never work on non systemd distros. Currently the logic
always assumes systemd is available and will fail with an error, so users
are forced to always run with `--no-healthcheck` to disable healthchecks
that are defined in an image for example. This is annoying and IMO
unnecessary, we should just default to no healthcheck on these systems.
First, use the systemd build tag to disable it at build time if this tag
is not used.
Second, use make sure systemd is used as init before trying
to use healthchecks. This could be the case when we are run in a container.
[NO NEW TESTS NEEDED] We do not have any non systemd VMs in CI AFAIK.

This just calls GC on the local storage, which will remove any leftover
directories from previous containers that are not in the podman db anymore.
This is useful primarily for transient store mode, but can also help in
the case of an unclean shutdown.
Also adds some e2e test to ensure prune --external works.

This brings a performance improvement to `podman run` on top of the
other transient_store improvements in containers/storage:
Transient mode without transient bolt_db:
Benchmark 1: bin/podman run --transient-store=true --rm --pull=never --network=host --security-opt seccomp=unconfined fedora true
Time (mean ± σ): 130.6 ms ± 5.8 ms [User: 44.4 ms, System: 25.9 ms]
Range (min … max): 122.6 ms … 143.7 ms 21 runs
Transient mode with transient bolt_db:
Benchmark 1: bin/podman run --transient-store=true --rm --pull=never --network=host --security-opt seccomp=unconfined fedora true
Time (mean ± σ): 100.3 ms ± 5.3 ms [User: 40.5 ms, System: 24.9 ms]
Range (min … max): 93.0 ms … 111.6 ms 29 runs

This handles the transient store options from the container/storage
configuration in the runtime/engine.
Changes are:
* Print transient store status in `podman info`
* Print transient store status in runtime debug output
* Add --transient-store argument to override config option
* Propagate config state to conmon cleanup args so the callback podman
gets the same config.
Note: This doesn't really change any behaviour yet (other than the changes
in containers/storage).

Startup healthchecks are similar to K8S startup probes, in that
they are a separate check from the regular healthcheck that runs
before it. If the startup healthcheck fails repeatedly, the
associated container is restarted.

Fix swapped NetInput and NetOutput container stats. This resulted
in `podman stats` showing outgoing traffic as NetInput and incoming
traffic as NetOutput. This change might be visible or cause problems
for users who are actively relying on those stats for monitoring reasons.

Since mountStorage and createNetNS run in parallel, the directory file
descriptors used by mountStorage were (rarely) propagated to the CNI
plugins. On FreeBSD, the CNI bridge plugin needs to make changes to the
network jail. This fails if there are any descriptors to open directories
to protect against host directories being visible to the jail's chroot.
Adding O_CLOEXEC to the unix.Open call in openDirectory ensures that these
descriptors are not visible to podman's child processes.

When restarting a container, clean up the healthcheck state by removing
the old log on disk. Carrying over the old state can lead to various
issues, for instance, in a wrong failing streak and hence wrong
behaviour after the restart.

Conceptually equivalent to networking by means of slirp4netns(1),
with a few practical differences:
- pasta(1) forks to background once networking is configured in the
namespace and quits on its own once the namespace is deleted:
file descriptor synchronisation and PID tracking are not needed
- port forwarding is configured via command line options at start-up,
instead of an API socket: this is taken care of right away as we're
about to start pasta
- there's no need for further selection of port forwarding modes:
pasta behaves similarly to containers-rootlessport for local binds
(splice() instead of read()/write() pairs, without L2-L4
translation), and keeps the original source address for non-local
connections like slirp4netns does
- IPv6 is not an experimental feature, and enabled by default. IPv6
port forwarding is supported
- by default, addresses and routes are copied from the host, that is,
container users will see the same IP address and routes as if they
were in the init namespace context. The interface name is also
sourced from the host upstream interface with the first default
route in the routing table. This is also configurable as documented
- sandboxing and seccomp(2) policies cannot be disabled
- only rootless mode is supported.
See https://passt.top for more details about pasta.
Also add a link to the maintained build of pasta(1) manual as valid
in the man page cross-reference checks: that's where the man page
for the latest build actually is -- it's not on Github and it doesn't
match any existing pattern, so add it explicitly.
