runc considers libcontainer to be "unstable" (not for external use),
so we try not to use it. Commit ed47d6ba76
brought back the dependency on other parts of libcontainer, but looks to
be only depending on a single utility, which in itself was borrowed from
github.com/coreos/go-systemd to not introduce CGO code in the same package.
This patch copies the version from github.com/coreos/go-systemd (adding
proper attribution, although the function is pretty trivial).
runc is in process of moving the libcontainer/user package to an external
module, which means we can remove the dependency on libcontainer entirely
in the near future. There is one more use of `libcontainer` in our vendor
tree; it looks like CDI is depending on one utility (devices.DeviceFromPath);
a943033a8b/vendor/github.com/container-orchestrated-devices/container-device-interface/pkg/cdi/container-edits_unix.go (L38)
We should remove the dependency on that utility, and add a CI check to
prevent bringing it back.

The rpc only reports one field, i.e. the cgroup driver, to kubelet.
Containerd determines the effective cgroup driver by looking at all
runtime handlers, starting from the default runtime handler (the rest in
alphabetical order), and returning the cgroup driver setting of the
first runtime handler that supports one. If no runtime handler supports
cgroup driver (i.e. has a config option for it) containerd falls back to
auto-detection, returning systemd if systemd is running and cgroupfs
otherwise.

This brings in a ton of great improvements, most notably for the containerd
daemon is performance improvements for cgroups1 and 2 for gathering stats,
as well as some fixes for enabling controllers and deleting v1 cgroups.

release notes: https://github.com/opencontainers/runc/releases/tag/v1.1.6
full diff: opencontainers/runc@v1.1.5...v1.1.6
This is the sixth patch release in the 1.1.z series of runc, which fixes
a series of cgroup-related issues.
Note that this release can no longer be built from sources using Go
1.16. Using a latest maintained Go 1.20.x or Go 1.19.x release is
recommended. Go 1.17 can still be used.
- systemd cgroup v1 and v2 drivers were deliberately ignoring UnitExist error
from systemd while trying to create a systemd unit, which in some scenarios
may result in a container not being added to the proper systemd unit and
cgroup.
- systemd cgroup v2 driver was incorrectly translating cpuset range from spec's
resources.cpu.cpus to systemd unit property (AllowedCPUs) in case of more
than 8 CPUs, resulting in the wrong AllowedCPUs setting.
- systemd cgroup v1 driver was prefixing container's cgroup path with the path
of PID 1 cgroup, resulting in inability to place PID 1 in a non-root cgroup.
- runc run/start may return "permission denied" error when starting a rootless
container when the file to be executed does not have executable bit set for
the user, not taking the CAP_DAC_OVERRIDE capability into account. This is
a regression in runc 1.1.4, as well as in Go 1.20 and 1.20.1
- cgroup v1 drivers are now aware of misc controller.

We will use this in future commits to see if the kubelet requested idmap
mounts for volumes, that we don't yet support.
