switch c/common to use runc cgroup creation so that we can use resource limits
This entails importing the newly refactored runc code to manage reading from and writing to cgroup.
vendoring in directly an unreleased runc commit from opencontainers/runc#3452
Signed-off-by: cdoern <cdoern@redhat.com>
The new `libimage` package is an attempt to consolidate the code for
managing container images and performing operations on them such as
pulling, pushing, saving, searching, local lookups, removing etc.
Over time, Buildah, CRI-O and Podman diverged with respect to managing
container images resulting in a high amount of code duplication
rendering the tools harder to maintain (e.g., bug fixes) and harder to
extend (e.g., adding new features) than necessary.
The desire to share all that code in a common library grew and this is
an attempt to address the it.
The changes as they are now pass Buildah CI [1]. Once merged into
Buildah, I expect follow up changes when migrating Podman over to
`libimage`.
Miscellaneous changes:
* Copy `podman/pkg/signal` to `pkg/signal`.
* Copy `buildah/manifests` to `image/manifests`. Note that the unit
tests require root privileges. Skip()'s are added when running
rootless. Currently excluded from linting.
* Copy `buildah/pkg/manifests` to `pkg/manifests`. Currently excluded
from linting.
* Copy `buildah/pkg/supplemented` to `pkg/supplemented`. Currently
excluded from linting.
