systemd uses SIGRTMIN+n signals, but containerd didn't support the signals
since Go's sys/unix doesn't support them.
This change introduces SIGRTMIN+n handling by utilizing moby/sys/signal.
Fixes#5402.

add '--snapshotter-labels' in ctr run and ctr c create
which can pass labels to snappshotter on preparing new
snapshot.
Pass command label to snapshotter can help it determine
which kind of writable snapshots should be provide.
For some snapshotter, such as overlaybd:
( https://github.com/alibaba/accelerated-container-image ),
it can provide 2 kind of writable snapshot (overlayfs dir or
blockdevice) by command label values.

FreeBSD mount options may have embedded = characters. For example,
devfs(5) supports the `ruleset` option which can be passed as
`ruleset=4` to indicate that ruleset 4 should be used.

Handle initial pty resize after the exec process has started and the pty
is available, consistent with the behavior of ctr run.

Use cio.WithStreams with explicit console device when --tty is passed,
consistent with how ctr run behaves.

This enables cases where devices exist in a subdirectory of /dev,
particularly where those device names are not portable across machines,
which makes it problematic to specify from a runtime such as cri.
Added this to `ctr` as well so I could test that the code at least
works.

The provides additional insight into how much time is being spent in
unpacking and is helpful in performance comparison for just this stage
without resorting to running under time command in linux for example.

Go example:
```go
opts := []converter.Opt{
// convert Docker media types to OCI ones
converter.WithDocker2OCI(true),
// convert tar.gz layers to uncompressed tar layers
converter.WithLayerConvertFunc(uncompress.LayerConvertFunc),
}
srcRef := "example.com/foo:orig"
dstRef := "example.com/foo:converted"
dstImg, err = converter.Convert(ctx, client, dstRef, srcRef, opts...)
fmt.Println(dstImg.Target)
```
ctr example: `ctr images convert --oci --uncompress example.com/foo:orig example.com/foo:converted`
Go test: `go test -exec sudo -test.root -test.run TestConvert`
The implementation is from https://github.com/containerd/stargz-snapshotter/pull/224,
but eStargz-specific functions are not included in this PR.
eStargz converter can be specified by importing `estargz` package and using `WithLayerConvertFunc(estargz.LayerConvertFunc)` option.
This converter interface will be potentially useful for converting zstd and ocicrypt layers as well.

The additional []containerd.RemoteOpt is not used by ctr currently,
but planned to be used by nerdctl and also probably by stargz's ctr-remote.

This adds linux cni support to `ctr run` via a `--cni` flag. This uses the
default configuration for CNI on `ctr` to configure the network namespace for a
container.
