CRIU's pre-copy migration support relies on the soft dirty page tracking
in the Linux kernel:
https://www.kernel.org/doc/Documentation/vm/soft-dirty.txt
This functionality is not implemented for all architectures and it can
also be turned off in the kernel.
CRIU can check if the combination of architecture/kernel/CRIU supports
the soft dirty page tracking and exports this feature checking
functionality in go-criu.
This commit adds an early check if the user selects pre-copy
checkpointing to error out if the system does not support it.

Fixes#11089 - cleanup PATH on MSI uninstall
Additionally fixes scenarios where the path can be overwritten by setx
Also removes the console flash, since the helper is built as a silent gui
Helper executable can be rerun by user to repair PATHs broken by other tools
Utilizes executable location instead of passed parameters to remove delicate escaping requirements

DevShmCheckpointTar constant has been recently introduced in
checkpointctl. This constant will be used in subsequent patch and this
patch contains auto-generated changes with the following commands:

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.
