golang.org/x/net contains a fix for CVE-2022-41717, which was addressed
in stdlib in go1.19.4 and go1.18.9;
> net/http: limit canonical header cache by bytes, not entries
>
> An attacker can cause excessive memory growth in a Go server accepting
> HTTP/2 requests.
>
> HTTP/2 server connections contain a cache of HTTP header keys sent by
> the client. While the total number of entries in this cache is capped,
> an attacker sending very large keys can cause the server to allocate
> approximately 64 MiB per open connection.
>
> This issue is also fixed in golang.org/x/net/http2 v0.4.0,
> for users manually configuring HTTP/2.

Add a common NRI 'service' plugin. It takes care of relaying
requests and respones to and from NRI (external NRI plugins)
and the high-level containerd namespace-independent logic of
applying NRI container adjustments and updates to actual CRI
and other containers.
The namespace-dependent details of the necessary container
manipulation operations are to be implemented by namespace-
specific adaptations. This NRI plugin defines the API which
such adaptations need to implement.

This was updated in 470d3ee057, but we
only needed the ebpf update. As nothing depends on this module anymore,
other than for the stats package (which didn't change in between), we
can (for now) roll it back to v1.0.4, and just force the newer ebpf
package.
Things rolled back (doesn't affect vendored code);

go.mod doesn't always do a great job on keeping the dependencies grouped in the
right block; 2b60770c4b added an extra "require"
block, after which things went downward.
This patch is grouping them back in the right block to nudge it in the right
direction.

Add spans around image unpack operations
Use image.ref to denote image name and image.id for the image config digest
Add top-level spand and record errors in the CRI instrumentation service
ArgsEscaped has now been merged into upstream OCI image spec.
This change removes the workaround we were doing in containerd
to deserialize the extra json outside of the spec and instead
just uses the formal spec types.

Some minor improvements, but biggest for here is ErrPipeListenerClosed
is no longer an errors.New where the string matches the text of the now
exported net.ErrClosed in the stdlib, but is just assigned to net.ErrClosed
directly. This should allow us to get rid of the string check for "use of closed
network connection" here now..

These functions were originally copied from the docker / moby repository in
4a7a8efc2d. Migrating these functions to use the
github.com/moby/sys/sequential module allows them being shared between moby,
docker/cli, and containerd, and to allow using them without importing all of sys
which also depends on hcsshim and more.
