In Go 1.16 `net.ErrClosed` was exported, removing the need to check the
exact text of "use of closed network connection". The stdlib's net listeners
are all setup for this to be a reality, but on Windows containerd uses the
the go-winio projects named pipe implementation as the listener for services.
Before version 0.6.0 this project returned a different error named
`ErrPipeListenerClosed` for using a closed pipe, where this error was just
an `errors.New` with the same text as `net.ErrClosed`, so checking against
`net.ErrClosed` wasn't possible.
Starting in 0.6.0 go-winio has that error assigned to `net.ErrClosed` directly
so this *should* be alright to finally change.

For Kata Containers, starting a privileged container will fail
if passing all host devices to container due to the permission

add a `privileged-without-host-devices` to `ctr run` command will

Previously we were reassigning os.Stderr to the panic.log file we create
when getting asked to run Containerd as a Windows service. The panic.log
file was used as a means to easily collect panic stacks as Windows
services don't have regular standard IO, and the usual recommendation
is to either write to the event log or just to a file in the case of
running as a service.
One place where this panic.log flow was biting us was with shim logging,
which is forwarded from the shim and copied to os.Stderr directly which was
causing shim logs to get forwarded to this panic.log file instead of just
panics. We expose an additional `--log-file` flag if you ask to run a
windows service which is the main way you'd get Containerd logs, and with
this change all of the shim logging which would today end up in panic.log
will now also go to this log file.

Added new runc shim binary in integration testing.
The shim is named by io.containerd.runc-fp.v1, which allows us to use
additional OCI annotation `io.containerd.runtime.v2.shim.failpoint.*` to
setup shim task API's failpoint. Since the shim can be shared with
multiple container, like what kubernetes pod does, the failpoint will be
initialized during setup the shim server. So, the following the
container's OCI failpoint's annotation will not work.
This commit also updates the ctr tool that we can use `--annotation` to
specify annotations when run container. For example:
```bash
➜ ctr run -d --runtime runc-fp.v1 \
--annotation "io.containerd.runtime.v2.shim.failpoint.Kill=1*error(sorry)" \
docker.io/library/alpine:latest testing sleep 1d
➜ ctr t ls
TASK PID STATUS
testing 147304 RUNNING
➜ ctr t kill -s SIGKILL testing
ctr: sorry: unknown
➜ ctr t kill -s SIGKILL testing
➜ sudo ctr t ls
TASK PID STATUS
testing 147304 STOPPED
```
The runc-fp.v1 shim is based on core runc.v2. We can use it to inject
failpoint during testing complicated or big transcation API, like
kubernetes PodRunPodsandbox.

Currently, ctr import will use loose matching as defined by
platforms.Only(), meaning in the case of platform linux/amd64 as in
issue#6441, importing will also match linux/386 platform on the
image-to-be-imported's index. However, that image-to-be-imported may not
have both the linux/amd64 and linux/386 platform contents, resulting in
a failure to unpack the image. This change makes that check strict such
that the requested platform to import for is the only platform content
imported. Both ctr pull and ctr export will treat the platform option as
strict, so this change makes ctr import consistent with those.

Schema 1 has been substantially deprecated since circa. 2017 in favor of Schema 2 introduced in Docker 1.10 (Feb 2016)
and its successor OCI Image Spec v1, but we have not officially deprecated Schema 1.
One of the reasons was that Quay did not support Schema 2 so far, but it is reported that Quay has been
supporting Schema 2 since Feb 2020 (moby/buildkit issue 409).
This PR deprecates pulling Schema 1 images but the feature will not be removed before containerd 2.0.
Pushing Schema 1 images was never implemented in containerd (and its consumers such as BuildKit).
Docker/Moby already disabled pushing Schema 1 images in Docker 20.10 (moby/moby PR 41295),
but Docker/Moby has not yet disabled pulling Schema 1 as containerd has not yet deprecated Schema 1.
(See the comments in moby/moby PR 42300.)
Docker/Moby is expected to disable pulling Schema 1 images in future after this deprecation.

This patch adds support for a container annotation and two separate
pod annotations for controlling the blockio class of containers.
The container annotation can be used by a CRI client:
"io.kubernetes.cri.blockio-class"
Pod annotations specify the blockio class in the K8s pod spec level:
"blockio.resources.beta.kubernetes.io/pod"
(pod-wide default for all containers within)
"blockio.resources.beta.kubernetes.io/container.<container_name>"
(container-specific overrides)
Correspondingly, this patch adds support for --blockio-class and
--blockio-config-file to ctr, too.
This implementation follows the resource class annotation pattern
introduced in RDT and merged in commit 893701220.

For some runtimes, the container is not ready for exec until the
initial container task has been started (as opposed to just having the task created).
More specifically, running containerd-stress with --exec would break
with Kata Container shim, since the sandbox is not created until a
start is issued. By starting the container's primary task before adding
exec's, we can avoid:
```
error="cannot enter container exec-container-1, with err Sandbox not running, impossible to enter the container: unknown"
```

In linux 5.14 and hopefully some backports, core scheduling allows processes to
be co scheduled within the same domain on SMT enabled systems.
The containerd impl sets the core sched domain when launching a shim. This
allows a clean way for each shim(container/pod) to be in its own domain and any
additional containers, (v2 pods) be be launched with the same domain as well as
any exec'd process added to the container.
