The ListContainers API previously had a Pod parameter, which
determined if pod name was returned (but, notably, not Pod ID,
which was returned unconditionally). This was fairly confusing,
so we decided to deprecate/remove the parameter and return it
unconditionally.
To do this without serious performance implications, we need to
avoid expensive JSON decodes of pod configuration in the DB. The
way our Bolt tables are structured, retrieving name given ID is
actually quite cheap, but we did not expose this via the Libpod
API. Add a new GetName API to do this.

The problem is that the default route was hardcoded to IPv4, this

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.

In `podman inspect` output for containers and pods, we include
the command that was used to create the container. This is also
used by `podman generate systemd --new` to generate unit files.
With remote podman, the generated create commands were incorrect
since we sourced directly from os.Args on the server side, which
was guaranteed to be `podman system service` (or some variant
thereof). The solution is to pass the command along in the
Specgen or PodSpecgen, where we can source it from the client's
os.Args.
This will still be VERY iffy for mixed local/remote use (doing a
`podman --remote run ...` on a remote client then a
`podman generate systemd --new` on the server on the same
container will not work, because the `--remote` flag will slip
in) but at the very least the output of `podman inspect` will be
correct. We can look into properly handling `--remote` (parsing
it out would be a little iffy) in a future PR.

The infra/abi code for pods was written in a flawed way, assuming
that the map[string]error containing individual container errors
was only set when the global error for the pod function was nil;
that is not accurate, and we are actually *guaranteed* to set the
global error when any individual container errors. Thus, we'd
never actually include individual container errors, because the
infra code assumed that err being set meant everything failed and
no container operations were attempted.
We were originally setting the cause of the error to something
nonsensical ("container already exists"), so I made a new error
indicating that some containers in the pod failed. We can then
ignore that error when building the report on the pod operation
and actually return errors from individual containers.
Unfortunately, this exposed another weakness of the infra code,
which was discarding the container IDs. Errors from individual
containers are not guaranteed to identify which container they
came from, hence the use of map[string]error in the Pod API
functions. Rather than restructuring the structs we return from
pkg/infra, I just wrapped the returned errors with a message
including the ID of the container.

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].

As part of APIv2 Attach, we need to be able to attach to freshly
created containers (in ContainerStateConfigured). This isn't
something Libpod is interested in supporting, so we use Init() to
get the container into ContainerStateCreated, in which attach is
possible. Problem: Init() will fail if dependencies are not
started, so a fresh container in a fresh pod will fail. The
simplest solution is to extend the existing recursive start code
from Start() to Init(), allowing dependency containers to be
started when we initialize the container (optionally, controlled
via bool).
Also, update some comments in container_api.go to make it more
clear how some of our major API calls work.

These were part of Podman v1.9, but were lost in the transition
to using Specgen to create containers. Most resource limits are
checked via the sysinfo package to ensure they are safe to use
(the cgroup is mounted, kernel support is present, etc) and
removed if not safe. Further, bounds checks are performed to
ensure that values are valid.
Ensure these warnings are printed client-side when they occur.
This part is a little bit gross, as it happens in pkg/infra and
not cmd/podman, which is largely down to how we implemented
`podman run` - all the work is done in pkg/infra and it returns
only once the container has exited, and we need warnings to print
*before* the container runs. The solution here, while inelegant,
avoid the need to extensively refactor our handling of run.
Should fix blkio-limit warnings that were identified by the FCOS
test suite.

This started as a small fix to `podman inspect` where a container
and image, with the same name/tag, were present, and
`podman inspect` was run on that name. `podman inspect` in 1.9
(and `docker inspect`) will give you the container; in v2.0, we
gave the image. This was an easy fix (just reorder how we check
for image/container).
Unfortunately, in the process of testing this fix, I determined
that we regressed in a different area. When you run inspect on
a number of containers, some of which do not exist,
`podman inspect` should return an array of inspect results for
the objects that exist, then print a number of errors, one for
each object that could not be found. We were bailing after the
first error, and not printing output for the containers that
succeeded. (For reference, this applied to images as well). This
required a much more substantial set of changes to properly
handle - signatures for the inspect functions in ContainerEngine
and ImageEngine, plus the implementations of these interfaces,
plus the actual inspect frontend code needed to be adjusted to
use this.
