Add support for simple rollbacks during `podman auto-update`. Rollbacks
are enabled by default. If a systemd unit cannot be restarted after an
update, the previous image will be retagged and the unit will be
restarted a second time.
Add system tests for rollbacks. Also fix a bug in the restart sequence;
we have to use the channel to actually know whether the restart was
successful or not.
NOTE: To make rollbacks really useful, users must run their containers
with `--sdnotify=container` such that the containers send the ready
message over the (mounted) socket. This way, restarting the systemd
units during auto update will block until the message has been received
(or a timeout kicked in).

this is the first pass at implementing init containers for podman pods.
init containersare made popular by k8s as a way to run setup for pods
before the pods standard containers run.
unlike k8s, we support two styles of init containers: always and
oneshot. always means the container stays in the pod and starts
whenever a pod is started. this does not apply to pods restarting.
oneshot means the container runs onetime when the pod starts and then is
removed.

The rootlessport forwarder requires a child IP to be set. This must be a
valid ip in the container network namespace. The problem is that after a
network disconnect and connect the eth0 ip changed. Therefore the
packages are dropped since the source ip does no longer exists in the
netns.
One solution is to set the child IP to 127.0.0.1, however this is a
security problem. [1]
To fix this we have to recreate the ports after network connect and
disconnect. To make this work the rootlessport process exposes a socket
where podman network connect/disconnect connect to and send to new child
IP to rootlessport. The rootlessport process will remove all ports and
recreate them with the new correct child IP.
Also bump rootlesskit to v0.14.3 to fix a race with RemovePort().

This adds support to checkpoint containers out of pods and restore
container into pods.
It is only possible to restore a container into a pod if it has been
checkpointed out of pod. It is also not possible to restore a non pod
container into a pod.
The main reason this does not work is the PID namespace. If a non pod
container is being restored in a pod with a shared PID namespace, at
least one process in the restored container uses PID 1 which is already
in use by the infrastructure container. If someone tries to restore
container from a pod with a shared PID namespace without a shared PID
namespace it will also fail because the resulting PID namespace will not
have a PID 1.

The rather raw and scarce output of `podman auto-update` has been a
thorn in my eyes for a longer while. So far, Podman would only print
updated systemd units, one per line, without further formatting.
Motivated by issue #9949 which is asking for some more useful
information in combination with a dry-run feature, I sat down and
reflected which information may come in handy.
Running `podman auto-update` will now look as follows:
```
$ podman auto-update
Trying to pull [...]
UNIT CONTAINER IMAGE POLICY UPDATED

Commit 748826fc88 fixed a bug where slow mounting of the runroot was
causing issues when the units are started at boot. The fix was to add
the container's runroot to the required mounts; the graph root has been
added as well.
Hard-coding the run- and graphroot to the required mounts, however,
breaks the portability of units generated with --now. Those units are
intended to be running on any machine as, theoreticaly, any user.
Make the mounts portable by using the `%t` macro for the run root.
Since the graphroot's location varies across root and ordinary users,
drop it from the list of required mounts. The graphroot was not causing
issues.

Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.
Note that I tried to leave bread crumbs for changed tests.
Miscellaneous changes:
* Some errors yield different messages which required to alter some
tests.
* I fixed some pre-existing issues in the code. Others were marked as
`//TODO`s to prevent the PR from exploding.
* The `NamesHistory` of an image is returned as is from the storage.
Previously, we did some filtering which I think is undesirable.
Instead we should return the data as stored in the storage.
* Touched handlers use the ABI interfaces where possible.
* Local image resolution: previously Podman would match "foo" on
"myfoo". This behaviour has been changed and Podman will now
only match on repository boundaries such that "foo" would match
"my/foo" but not "myfoo". I consider the old behaviour to be a
bug, at the very least an exotic corner case.
* Futhermore, "foo:none" does *not* resolve to a local image "foo"
without tag anymore. It's a hill I am (almost) willing to die on.
* `image prune` prints the IDs of pruned images. Previously, in some
cases, the names were printed instead. The API clearly states ID,
so we should stick to it.
* Compat endpoint image removal with _force_ deletes the entire not
only the specified tag.

It is rare but possible that storage locations for the graphroot and the
runroot are not mounted at boot time, and therefore might race when

slow tmpfs mount for the runroot would suddenly mount over /run, causing
the container to lose all currently-running data, requiring a system
refresh to get it back.

The rest of this document claims that the argument is called '--time',
not '--timeout', and that the value is expressed in seconds. As
currently written, the example (which ostensibly runs the API service
for 5 seconds) uses the '--timeout' spelling (which actually does work,
as an undocumented alias) and passes a value of '5000', which is more
than an hour. Fix both.
[NO TESTS NEEDED] as this is a simple documentation change.

Implement podman secret create, inspect, ls, rm
Implement podman run/create --secret
Secrets are blobs of data that are sensitive.
Currently, the only secret driver supported is filedriver, which means creating a secret stores it in base64 unencrypted in a file.
After creating a secret, a user can use the --secret flag to expose the secret inside the container at /run/secrets/[secretname]
This secret will not be commited to an image on a podman commit

Backstory: every time you run 'make podman' or even
just 'make', you get a full recompile. This is sub-ideal.
Cause: I don't really know. It looks complicated. #5017
introduced a .PHONY for bin/podman, for reasons not
explained in the PR. Then, much later, #5880 well-
intentionedly but improperly tweaked the 'find'
command used in defining SOURCES, adding a -prune
but without the corresponding and required -print.
Let's just say, it was an unfortunate cascade of events.
This PR fixes the SOURCES definition and removes the
highly-undesired .PHONY from podman & podman-remote,
making it so you can type 'make' and, oh joy, not
build anything if it's current. The way 'make' is
supposed to work.
Why fix this now? Because my PR (#9209) was failing in CI,
in the Validate step:
Can't exec "./bin/podman": No such file or directory at hack/xref-helpmsgs-manpages line 223.
It failed even on Re-run, and only passed once I force-pushed
the PR (with no changes, just a new commit SHA). I have no idea
why bin/podman wasn't built, and I have zero interest in pursuing
that right now, but the proper solution is to add bin/podman as
a Makefile dependency for that particular test. So done.
While I'm at it, fix what is pretty clearly a typo in a .PHONY
And, finally, fix a go-md2man warning introduced in #9189

Currently podman implements --override-arch and --overide-os
But Podman has made these aliases for --arch and --os. No
reason to have to specify --override, since it is clear what
the user intends.
Currently if the user specifies an --override-arch field but the
image was previously pulled for a different Arch, podman run uses
the different arch. This PR also fixes this issue.

When doing a podman images, manifests lists look just like images, so
it is logical that users would assume that they can just podman push them
to a registry. The problem is we throw out weird errors when this happens
and users need to somehow figure out this is a manifest list rather then
an image, and frankly the user will not understand the difference.
This PR will make podman push just do the right thing, by failing over and
attempting to push the manifest if it fails to push the image.
Fix up handling of manifest push
Protocol should bring back a digest string, which can either be
printed or stored in a file.
We should not reimplement the manifest push setup code in the tunnel
code but take advantage of the api path, to make sure remote and local
work the same way.

Basic theory: We remove the container, but *only from the DB*.
We leave it in c/storage, we leave the lock allocated, we leave
it running (if it is). Then we create an identical container with
an altered name, and add that back to the database. Theoretically
we now have a renamed container.
The advantage of this approach is that it doesn't just apply to
rename - we can use this to make *any* configuration change to a
container that does not alter its container ID.
Potential problems are numerous. This process is *THOROUGHLY*
non-atomic at present - if you `kill -9` Podman mid-rename things
will be in a bad place, for example. Also, we can't rename
containers that can't be removed normally - IE, containers with
dependencies (pod infra containers, for example).
The largest potential improvement will be to move the majority of
the work into the DB, with a `RecreateContainer()` method - that
will add atomicity, and let us remove the container without
worrying about depencies and similar issues.
Potential problems: long-running processes that edit the DB and
may have an older version of the configuration around. Most
notable example is `podman run --rm` - the removal command needed
to be manually edited to avoid this one. This begins to get at
the heart of me not wanting to do this in the first place...
This provides CLI and API implementations for frontend, but no
tunnel implementation. It will be added in a future release (just
held back for time now - we need this in 3.0 and are running low
on time).
This is honestly kind of horrifying, but I think it will work.

This implements support for mounting and unmounting volumes
backed by volume plugins. Support for actually retrieving
plugins requires a pull request to land in containers.conf and
then that to be vendored, and as such is not yet ready. Given
this, this code is only compile tested. However, the code for
everything past retrieving the plugin has been written - there is
support for creating, removing, mounting, and unmounting volumes,
which should allow full functionality once the c/common PR is
merged.
A major change is the signature of the MountPoint function for
volumes, which now, by necessity, returns an error. Named volumes
managed by a plugin do not have a mountpoint we control; instead,
it is managed entirely by the plugin. As such, we need to cache
the path in the DB, and calls to retrieve it now need to access
the DB (and may fail as such).
Notably absent is support for SELinux relabelling and chowning
these volumes. Given that we don't manage the mountpoint for
these volumes, I am extremely reluctant to try and modify it - we
could easily break the plugin trying to chown or relabel it.
Also, we had no less than *5* separate implementations of
inspecting a volume floating around in pkg/infra/abi and
pkg/api/handlers/libpod. And none of them used volume.Inspect(),
the only correct way of inspecting volumes. Remove them all and
consolidate to using the correct way. Compat API is likely still
doing things the wrong way, but that is an issue for another day.

When migrating a container with associated volumes, the content of
these volumes should be made available on the destination machine.
This patch enables container checkpoint/restore with named volumes
by including the content of volumes in checkpoint file. On restore,
volumes associated with container are created and their content is
restored.
The --ignore-volumes option is introduced to disable this feature.
Example:
# podman container checkpoint --export checkpoint.tar.gz <container>
The content of all volumes associated with the container are included
in `checkpoint.tar.gz`
# podman container checkpoint --export checkpoint.tar.gz --ignore-volumes <container>
The content of volumes is not included in `checkpoint.tar.gz`. This is
useful, for example, when the checkpoint/restore is performed on the
same machine.
# podman container restore --import checkpoint.tar.gz
The associated volumes will be created and their content will be
restored. Podman will exit with an error if volumes with the same
name already exist on the system or the content of volumes is not
included in checkpoint.tar.gz
# podman container restore --ignore-volumes --import checkpoint.tar.gz
Volumes associated with container must already exist. Podman will not
create them or restore their content.
