Setting port mappings only works when CNI is configuring our
network (or slirp4netns, in the rootless case). This is not the
case with `--net=host`, `--net=container:`, and joining the
network namespace of the pod we are part of. Instead of allowing
users to do these things and then be confused why they do
nothing, let's match Docker and return a warning that your port
mappings will do nothing.

if the kernel supports ambient capabilities (Linux 4.3+), also set

This is different that what Moby does, as ambient capabilities are

Currently it double counts connections because it's incrementing the
total for both the new and active states. Based on the comments, we
should only count new connections for the total count and perform the
timer stop actions when the connection has transitioned to an active
state.

The sig-proxy code is set up to error on failing to forward
signals to a container. This is reasonable in cases where the
container is running, but something strange went wrong - but when
the Kill fails because the container is stopped, we shouldn't
bother with aggressive Error logging since this is an expected
part of the container lifecycle - it stops, and then `podman run`
also stops, but there is a timing window in between where signals
will fail to be proxied, and we should not print angry errors
during that.

Most of the builtin golang functions like os.Stat and
os.Open report errors including the file system object
path. We should not wrap these errors and put the file path
in a second time, causing stuttering of errors when they
get presented to the user.
This patch tries to cleanup a bunch of these errors.

Containers that share IPC Namespaces share each others
/dev/shm, which means a private /dev/shm needs to be setup
for the infra container.
Added a system test and an e2e test to make sure the
/dev/shm is shared.

Add a new "image" mount type to `--mount`. The source of the mount is
the name or ID of an image. The destination is the path inside the
container. Image mounts further support an optional `rw,readwrite`
parameter which if set to "true" will yield the mount writable inside
the container. Note that no changes are propagated to the image mount
on the host (which in any case is read only).
Mounts are overlay mounts. To support read-only overlay mounts, vendor
a non-release version of Buildah.

If you use additional stores and pull the same image into
writable stores, you can end up with the situation where
you have the same image twice. This causes image exists
to return the wrong error. It should return true in this
situation rather then an error.

Followon to #7965 (mirror registry). mirror.gcr.io doesn't
cache all the images we need, and I can't find a way to
add to its cache, so let's just use quay.io for those
images that it can't serve.
Tools used:
skopeo copy --all docker://docker.io/library/alpine:3.10.2 \
docker://quay.io/libpod/alpine:3.10.2
...and also:
docker.io/library/alpine:3.2
docker.io/library/busybox:latest
docker.io/library/busybox:glibc
docker.io/library/busybox:1.30.1
docker.io/library/redis:alpine
docker.io/libpod/alpine-with-bogus-seccomp:label
docker.io/libpod/alpine-with-seccomp:label
docker.io/libpod/alpine_healthcheck:latest
docker.io/libpod/badhealthcheck:latest
Since most of those were new quay.io/libpod images, they required
going in through the quay.io GUI, image, settings, Make Public.

podman inspect only had the capabilities to inspect containers and images. if a user wanted to inspect a pod, volume, or network, they would have to use `podman network inspect`, `podman pod inspect` etc. Docker's cli allowed users to inspect both volumes and networks using regular inspect, so this commit gives the user the functionality
If the inspect type is not specified using --type, the order of inspection is:
containers
images
volumes
networks
pods
meaning if container that has the same name as an image, podman inspect would return the container inspect.
To avoid duplicate code, podman network inspect and podman volume inspect now use the inspect package as well. Podman pod inspect does not because podman pod inspect returns a single json object while podman inspect can return multiple)

Currently if you run an interactive session of podman run and
specifiy the --cidfile option, the cidfile will not get created
until the container finishes running. If you run a detached
container, it will get created right away. This Patch creates
the cidfile as soon as the container is created. This could allow
other tools to use the cidefile on all running containers.
