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
container-test.service 08fd34e533fd (test) localhost:5000/busybox registry false
```
Also refactor the spaghetti code in the backend a bit to make it easier
to digest and maintain.

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.

In the documentation source `--` is only used in long option names or
console output. Currently any unescaped `--` that's not in a code
block/inline gets converted into a single "en dash". This is confusing
to the reader because long options start with two dashes, not one.
This switches off the dash transformation in Sphinx. Quotation marks,
apostrophes and ellipses are still transformed as before.
It also switches off all smart transforms in the podman-remote windows
documentation build. This matches the Linux man page build, which
doesn't use smart transforms.

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.
