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.

For reasons buried in the history of Podman, looking up an untagged
image would match any tag of matching image. For instance, looking up
centos would match a local image centos:foobar. Change that behavior
to only match the latest tag.

Support downloading files, for instance via
`podman load -i server.com/image.tar`. The specified URL is downloaded
in the frontend and stored as a temp file that gets passed down to the
backend.
Also vendor in c/common@main to use the new `pkg/download`.

Health checks may be defined in the container config or the config of an
image. So far, Podman only looked at the container config.
The plumbing happened in libimage but add a regression test to Podman as
well to make sure the glue code will not regress.
Note that I am pinning github.com/onsi/gomega to v1.16.0 since v1.17.0
requires go 1.16 which in turn is breaking CI.

There was the question about how long it takes to create a checkpoint.
CRIU already provides some statistics about how long it takes to create
a checkpoint and similar.
With this change the file 'stats-dump' is included in the checkpoint
archive and the tool checkpointctl can be used to display these
statistics:
./checkpointctl show -t /tmp/cp.tar --print-stats
Displaying container checkpoint data from /tmp/dump.tar

Make sure that the value is only set if specified on the CLI. c/image
already defaults to true but if set in the system context, we'd skip
settings in the registries.conf.

Vendor the latest HEAD in c/common to pull in changes for a faster
inspection of images. Previously, only the size computation was
optional, now the one for the parent image is as well.
In many cases, the parent image is not needed but it takes around 10ms
on my local machine. With this change, we cut off 10ms from many code
paths, most importantly, container creation.

Update CNI so we can match wrapped errors. This should silence ENOENT
warnings when trying to read the cni conflist files.
Fixes#10926
Because CNI v1.0.0 contains breaking changes we have to change some
import paths. Also we cannot update the CNI version used for the
conflist files created by `podman network create` because this would
require at least containernetwork-plugins v1.0.1 and a updated dnsname
plugin. Because this will take a while until it lands in most distros
we should not use this version. So keep using v0.4.0 for now.
The update from checkpoint-restore/checkpointctl is also required to
make sure it no longer uses CNI to read the network status.

We do not use the ocicni code anymore so let's get rid of it. Only the
port struct is used but we can copy this into libpod network types so
we can debloat the binary.
The next step is to remove the OCICNI port mapping form the container
config and use the better PortMapping struct everywhere.

Make use of the new network interface in libpod.
This commit contains several breaking changes:
- podman network create only outputs the new network name and not file
path.
- podman network ls shows the network driver instead of the cni version
and plugins.
- podman network inspect outputs the new network struct and not the cni
conflist.
- The bindings and libpod api endpoints have been changed to use the new
network structure.
The container network status is stored in a new field in the state. The
status should be received with the new `c.getNetworkStatus`. This will
migrate the old status to the new format. Therefore old containers should
contine to work correctly in all cases even when network connect/
disconnect is used.
New features:
- podman network reload keeps the ip and mac for more than one network.
- podman container restore keeps the ip and mac for more than one
network.
- The network create compat endpoint can now use more than one ipam
config.
The man pages and the swagger doc are updated to reflect the latest
changes.
