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.

Before this change, for several of the services that `WithServices`
handles, only the grpc client is supported.
Now, for instance, one can use an `images.Store` directly instead of
only an `imagesapi.StoreSlient`.
Some of the methods have been renamed to satisfy the difference between
using a grpc `<Foo>Client` vs the main interface.
I did not see a good candidate for TaskService so have left that mostly
unchanged.

CNI plugins that need to wait for network state to converge
may want to cancel waiting when a short lived pod is deleted.
However, there is a race between when kubelet asks the runtime
to create the sandbox for the pod, and when the plugin is able
request the pod object from the apiserver. It may be the case
that the plugin receives the new pod, rather than the pod
the sandbox request was initiated for.
Passing the pod UID to the plugin allows the plugin to check
whether the pod it gets from the apiserver is actually the
pod its sandbox request was started for.

Similar to other deferred cleanup operations, teardownPodNetwork should
use a different context as the original context may have expired,
otherwise CNI wouldn't been invoked, leading to leak of network
resources, e.g. IP addresses.

This commit adds support for the PID namespace mode TARGET
when generating a container spec.
The container that is created will be sharing its PID namespace
with the target container that was specified by ID in the namespace
options.

Looks like we had our own copy of the "getDevices" code already, so use
that code (which also matches the code that's used to _generate_ the spec,
so a better match).
Moving the code to a separate file, I also noticed that the _unix and _linux
code was _exactly_ the same (baring some `//nolint:` comments), so also
removing the duplicated code.
With this patch applied, we removed the dependency on the libcontainer/devices
package (leaving only libcontainer/user).

Move `pkg/cri/opts.WithoutRunMount` function to `oci.WithoutRunMount`
so that it can be used without dependency on CRI.
Also add `oci.WithoutMounts(dests ...string)` for generality.

Currently image references end up being stored in a
random order due to the way maps are iterated through
in Go. This leads to inconsistent identifiers being
resolved when a single reference is needed to identify
an image and the ordering of the references is used for
the selection.
Sort references in a consistent and ranked manner,
from higher information formats to lower.
Note: A `name + tag` reference is considered higher
information than a `name + digest` reference since a
registry may be used to resolve the digest from a
`name + tag` reference.

golang has enabled RFC 6555 Fast Fallback (aka HappyEyeballs)
by default in 1.12.
It means that if a host resolves to both IPv6 and IPv4,
it will try to connect to any of those addresses and use the
working connection.
However, the implementation uses go routines to start both connections in parallel,
and this has limitations when running inside a namespace, so we try to the connections
serially, trying IPv4 first for keeping the same behaviour.
