Ensure that, if an error occurs somewhere along the way when we
remove a pod, it's preserved until the end and returned, even as
we continue to remove the pod.

Removing a pod must first removal all containers in the pod.
Libpod requires the state to remain consistent at all times, so
references to a deleted pod must all be cleansed first.
Pods can have many containers in them. We presently iterate
through all of them, and if an error occurs trying to clean up
and remove any single container, we abort the entire operation
(but cannot recover anything already removed - pod removal is not
an atomic operation).
Because of this, if a removal error occurs partway through, we
can end up with a pod in an inconsistent state that is no longer
usable. What's worse, if the error is in the infra container, and
it's persistent, we get zombie pods - completely unable to be
removed.
When we saw some of these same issues with containers not in
pods, we modified the removal code there to aggressively purge
containers from the database, then try to clean up afterwards.
Take the same approach here, and make cleanup errors nonfatal.
Once we've gone ahead and removed containers, we need to see
pod deletion through to the end - we'll log errors but keep
going.
Also, fix some other small things (most notably, we didn't make
events for the containers removed).

the remote-podman checkpoint and restore commands were done some time
ago but for some reason not added to the container subcommand
Signed-off-by: baude <bbaude@redhat.com>
After a reboot, when we refresh Podman's state, we retrieved the
lock from the fresh SHM instance, but we did not mark it as
allocated to prevent it being handed out to other containers and
pods.
Provide a method for marking locks as in-use, and use it when we
refresh Podman state after a reboot.

Only Fedora 29 and newer has an updated container-selinux and
selinux-policy new enough to support CRIU in restoring threaded
processes in a container with SELinux enabled.
Also skip checkpoint/restore tests if rootless. CRIU requires root.

Theory: it's SELinux blowing up and preventing us from creating
files as the container. Try and use a fresh dir and :Z to fix.

if checkAuth() success but not logged in with podman, assume it's logged in with docker and retrun the message.

We want to start supporting the registries.conf format.
Also start showing blocked registries in podman info
Fix sorting so all registries are listed together in podman info.
