This will be used when we allow 'podman ps' to display info on
storage containers instead of Libpod containers.

Lookup was written before volume states merged, but merged after,
and CI didn't catch the obvious failure here. Without a valid
state, we try to unmarshall into a null pointer, and 'volume rm'
is completely broken because of it.

When constructing VM cache-images, the latest/greatest podman package is
installed to ensure all necessary dependencies are met. Prior to
testing source-built binaries, most of of the packaged files are removed.
However, if the `io.podman` service or socket is enabled/running, it
could cause the packaged podman and varlink binaries to be both resident
and cached. Since this condition would cause very difficult to diagnose
behaviors, add preventative measures to ensure these services are absent
prior to removing packaged podman files.

Podman is not the only user of containers/storage, and as such we
cannot rely on our database as the sole source of truth when
pruning images. If images do not show as in use from Podman's
perspective, but subsequently fail to remove because they are
being used by a container, they're probably being used by Buildah
or another c/storage client.
Since the images in question are in use, we shouldn't error on
failure to prune them - we weren't supposed to prune them in the
first place.

This is mostly used with Systemd, which really wants to manage
CGroups itself when managing containers via unit file.

This change adds the following annotation to every container created by
podman:
```json
"Annotations": {
"io.containers.manager": "libpod"
}
```
Target of this annotaions is to indicate which project in the containers
ecosystem is the major manager of a container when applications share
the same storage paths. This way projects can decide if they want to
manipulate the container or not. For example, since CRI-O and podman are
not using the same container library (libpod), CRI-O can skip podman
containers and provide the end user more useful information.
A corresponding end-to-end test has been adapted as well.

Previously, we only did this for volumes created at the same time
as the container. However, this is not correct behavior - Docker
does so for all named volumes, even those made with
'podman volume create' and mounted into a container later.

This isn't included in Docker, but seems handy enough.
Use the new API for 'volume rm' and 'volume inspect'.

Make the errors more readable, with clearer instructions on

Do not require 0755 permissons for the ~/.config directory but require
at least 0700 which should be sufficient. The current implementation
internally creates this directory with 0755 if it does not exist, but if the
directory already exists with different perissions the current code returns
an empty string.

The bsd variant of `ln` does not support the ``-T`` option.
Testing for existence using wildcard before creating new symlinks
should be sufficient here. Furthermore the target directory is
managed internally by this Makefile anyway.

In the Dockerfiles that are used to build the podman images on
quay.io, we were changing the events_logger from journald to
file in libpod.conf, but we weren't enabling it as we didn't
remove the comment. This corrects that and addresses: #3464

We want to get podman info to tell us about the version of
the mount program to help us diagnose issues users are having.
Also if in rootless mode and slirp4netns is installed reveal package
info on slirp4netns.

If c/storage paths are explicitly set to "" (the empty string) it
will use compiled-in defaults. However, it won't tell us this via
`storage.GetDefaultStoreOptions()` - we just get the empty string
(which can put our defaults, some of which are relative to
c/storage, in a bad spot).
Hardcode a sane default for cases like this. Furthermore, add
some sanity checks to paths, to ensure we don't use relative
paths for core parts of libpod.

When we fail to remove a container's SHM, that's an error, and we
need to report it as such. This may be part of our lingering
storage woes.
Also, remove MNT_DETACH. It may be another cause of the storage
removal failures.

When volume options and the local volume driver are specified,
the volume is intended to be mounted using the 'mount' command.
Supported options will be used to volume the volume before the
first container using it starts, and unmount the volume after the
last container using it dies.
This should work for any local filesystem, though at present I've
only tested with tmpfs and btrfs.
