The linter ensures a common code style.
- use switch/case instead of else if
- use if instead of switch/case for single case statement
- add space between comment and text
- detect the use of defer with os.Exit()
- use short form var += "..." instead of var = var + "..."
- detect problems with append()
```
newSlice := append(orgSlice, val)
```
This could lead to nasty bugs because the orgSlice will be changed in
place if it has enough capacity too hold the new elements. Thus we
newSlice might not be a copy.
Of course most of the changes are just cosmetic and do not cause any
logic errors but I think it is a good idea to enforce a common style.
This should help maintainability.

The Docker-compatible REST API has historically behaved just as the rest
of Podman and Buildah (and the atomic Docker in older RHEL/Fedora) where
`containers-registries.conf` is centrally controlling which registries
a short name may resolve to during pull or local image lookups. Please
refer to a blog for more details [1].
Docker, however, is only resolving short names to docker.io which has
been reported (see #12320) to break certain clients who rely on this
behavior. In order to support this scenario, `containers.conf(5)`
received a new option to control whether Podman's compat API resolves
to docker.io only or behaves as before.
Most endpoints allow for directly normalizing parameters that represent
an image. If set in containers.conf, Podman will then normalize the
references directly to docker.io. The build endpoint is an outlier
since images are also referenced in Dockerfiles. The Buildah API,
however, supports specifying a custom `types.SystemContext` in which
we can set a field that enforces short-name resolution to docker.io
in `c/image/pkg/shortnames`.
Notice that this a "hybrid" approach of doing the normalization directly
in the compat endpoints *and* in `pkg/shortnames` by passing a system
context. Doing such a hybrid approach is neccessary since the compat
and the libpod endpoints share the same `libimage.Runtime` which makes
a global enforcement via the `libimage.Runtime.systemContext`
impossible. Having two separate runtimes for the compat and the libpod
endpoints seems risky and not generally applicable to all endpoints.

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.

When the query decoding fails at the beginning of WaitContainerLibpod(),
the Error() sets the header but doesn't returns after that.
This causes the execution flow to reach the WriteResponse() at the end
of WaitContainerLibpod(), which attempts to set another header, thus
causing the following error:

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

Listing images has shown increasing performance penalties with an
increasing number of images. Unless `--all` is specified, Podman
will filter intermediate images. Determining intermediate images
has been done by finding (and comparing!) parent images which is
expensive. We had to query the storage many times which turned it
into a bottleneck.
Instead, create a layer tree and assign one or more images to nodes that
match the images' top layer. Determining the children of an image is
now exponentially faster as we already know the child images from the
layer graph and the images using the same top layer, which may also be
considered child images based on their history.
On my system with 510 images, a rootful image list drops from 6 secs
down to 0.3 secs.
Also use the tree to compute parent nodes, and to filter intermediate
images for pruning.

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules. While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.
Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`. The renaming of the imports
was done via `gomove` [1].
