Currently we are mounting /dev/shm from disk, it should be from a tmpfs.
User Namespace supports tmpfs mounts for nonroot users, so this section of
code should work fine in bother root and rootless mode.

Don't try to argparse command-line arguments on the right-hand
side of the image; those are intended for the container command:
pypodman create fedora ls -l
pypodman run fedora find / -name foo
pypodman run fedora bash -c 'echo hi'
If/when `pypodman exec` gets implemented, it should use this too.

with https://github.com/opencontainers/runc/pull/1807 we moved the
systemd notify initialization from "create" to "start", so that the
OCI runtime doesn't hang while waiting on reading from the notify
socket. This means we also need to set the correct NOTIFY_SOCKET when
start'ing the container.

We regressed on this at some point. Adding a new test should help
ensure that doesn't happen again.

We now default to setting storage options to "nodev", when running
privileged containers, we need to turn this off so the processes can
manipulate the image.

prefer a fsnotify watcher to polling the file, we take advantage of
inotify on Linux and react more promptly to the PID file being
created.
If the watcher cannot be created, then fallback to the old polling
mechanism.

do not store the entire file but only the subset of what we have
modified. Also, we were not writing the correct data. Since it is
not trivial to serialize storage.conf correctly and all the various
supported options, serialize only what we care about.

The conmon exit command is running inside of a namespace where the
process is running with uid=0. When it launches again podman for the
cleanup, podman is not running in rootless mode as the uid=0.
Export some more env variables to tell podman we are in rootless
mode.

This adds checkpoint/restore test cases for the newly added options

podman container restore -a was using the wrong filter to restore
checkpointed containers. This switches from 'running' containers to
'exited' containers.
Restoring with -a only works if all exited containers have been
checkpointed. Maybe it would make sense to track which containers have
been really checkpointed. This is just to fix '-a' to work at least
if all exited containers have been checkpointed.

CRIU can checkpoint and restore processes/containers with established
TCP connections if the correct option is specified. To implement
checkpoint and restore with support for established TCP connections with
Podman this commit adds the necessary options to runc during checkpoint
and also tells conmon during restore to use 'runc restore' with
'--tcp-established'.
For this Podman feature to work a corresponding conmon change is
required.
Example:
$ podman run --tmpfs /tmp --name podman-criu-test -d docker://docker.io/yovfiatbeb/podman-criu-test
$ nc `podman inspect -l | jq -r '.[0].NetworkSettings.IPAddress'` 8080
GET /examples/servlets/servlet/HelloWorldExample
Connection: keep-alive
1
GET /examples/servlets/servlet/HelloWorldExample
Connection: keep-alive
2
$ # Using HTTP keep-alive multiple requests are send to the server in the container
$ # Different terminal:
$ podman container checkpoint -l
criu failed: type NOTIFY errno 0
$ # Looking at the log file would show errors because of established TCP connections
$ podman container checkpoint -l --tcp-established
$ # This works now and after the restore the same connection as above can be used for requests
$ podman container restore -l --tcp-established
The restore would fail without '--tcp-established' as the checkpoint image
contains established TCP connections.
