479eeac62c move editing of exitCode to runtime
There's no way to get the error if we successfully get an exit code (as it's just printed to stderr instead).
instead of relying on the error to be passed to podman, and edit based on the error code, process it on the varlink side instead

Also move error codes to define package

Add --ignore-rootfs option for checkpoint/restore
The newly added functionality to include the container's root
file-system changes into the checkpoint archive can now be explicitly
disabled. Either during checkpoint or during restore.

If a container changes a lot of files during its runtime it might be
more effective to migrated the root file-system changes in some other
way and to not needlessly increase the size of the checkpoint archive.

If a checkpoint archive does not contain the root file-system changes
information it will automatically be skipped. If the root file-system
changes are part of the checkpoint archive it is also possible to tell
Podman to ignore these changes.

Include root file-system changes in container migration
One of the last limitations when migrating a container using Podman's
'podman container checkpoint --export=/path/to/archive.tar.gz' was
that it was necessary to manually handle changes to the container's root
file-system. The recommendation was to mount everything as --tmpfs where
the root file-system was changed.

This extends the checkpoint export functionality to also include all
changes to the root file-system in the checkpoint archive. The
checkpoint archive now includes a tarstream of the result from 'podman
diff'. This tarstream will be applied to the restored container before
restoring the container.

With this any container can now be migrated, even it there are changes
to the root file-system.

There was some discussion before implementing this to base the root
file-system migration on 'podman commit', but it seemed wrong to do
a 'podman commit' before the migration as that would change the parent
layer the restored container is referencing. Probably not really a
problem, but it would have meant that a migrated container will always
reference another storage top layer than it used to reference during
initial creation.

a54429cf87 Use conmon pidfile in generated systemd unit as PIDFile.
By default, podman points PIDFile in generated unit file to non-existent
location. As a result, the unit file, generated by podman, is broken:
an attempt to start this unit without prior modification results in a crash,
because systemd can not find the pidfile of service's main process.

Fix the value of "PIDFile" and add a system test for this case.

d0a0a3fbd9 configure runtime without store
some podman commands do not require the use of a container/image store.
in those cases, it is more effecient to not open the store, because that
results in having to also close the store which can be costly when the
system is under heavy write I/O loads.

dd81a44ccf remove libpod from main
the compilation demands of having libpod in main is a burden for the
remote client compilations.  to combat this, we should move the use of
libpod structs, vars, constants, and functions into the adapter code
where it will only be compiled by the local client.

this should result in cleaner code organization and smaller binaries. it
should also help if we ever need to compile the remote client on
non-Linux operating systems natively (not cross-compiled).

49e696642d Add --storage flag to 'podman rm' (local only)
This flag switches to removing containers directly from c/storage
and is mostly used to remove orphan containers.

It's a superior solution to our former one, which attempted
removal from storage under certain circumstances and could, under
some conditions, not trigger.

Also contains the beginning of support for storage in `ps` but
wiring that in is going to be a much bigger pain.

Fixes #3329.

migration: add possibility to restore a container with a new name
The option to restore a container from an external checkpoint archive
(podman container restore -i /tmp/checkpoint.tar.gz) restores a
container with the same name and same ID as id had before checkpointing.

This commit adds the option '--name,-n' to 'podman container restore'.
With this option the restored container gets the name specified after
'--name,-n' and a new ID. This way it is possible to restore one
container multiple times.

If a container is restored with a new name Podman will not try to
request the same IP address for the container as it had during
checkpointing. This implicitly assumes that if a container is restored
from a checkpoint archive with a different name, that it will be
restored multiple times and restoring a container multiple times with
the same IP address will fail as each IP address can only be used once.

Added support to migrate containers
This commit adds an option to the checkpoint command to export a
checkpoint into a tar.gz file as well as importing a checkpoint tar.gz
file during restore. With all checkpoint artifacts in one file it is
possible to easily transfer a checkpoint and thus enabling container
migration in Podman. With the following steps it is possible to migrate
a running container from one system (source) to another (destination).

 Source system:
  * podman container checkpoint -l -e /tmp/checkpoint.tar.gz
  * scp /tmp/checkpoint.tar.gz destination:/tmp

 Destination system:
  * podman pull 'container-image-as-on-source-system'
  * podman container restore -i /tmp/checkpoint.tar.gz

The exported tar.gz file contains the checkpoint image as created by
CRIU and a few additional JSON files describing the state of the
checkpointed container.

Now the container is running on the destination system with the same
state just as during checkpointing. If the container is kept running
on the source system with the checkpoint flag '-R', the result will be
that the same container is running on two different hosts.

followed by a resize event.  this is fine for the local client but when
doing things over the varlink, the first sigwinch is wiped out by the
immediate resize event and is therefore lost.  by making the channel
buffered, both events are processed after the varlink connection is
