These opts either inherit the parent cgroup device.list or append the
default unix devices like /dev/null /dev/random so that the container
has access.

We introduce a WithSpecFromFile option combinator to allow creation
simpler creation of OCI specs from a file name. Often used as the first
option in a `SpecOpts` slice, it simplifies choosing between a local
file and the built-in default.
The code in `ctr run` has been updated to use the new option, with out
changing the order of operations or functionality present there.

Commit 05513284e7 exposed the "rootfs"
and "no-pivot" flags for the "containers" command, but it accidentally
removed them for "run" since package-level variables are initialized
before package-level init functions in golang. Hoisting these flags to
a package imported by both commands solves the problem.

Without this `ctr run` can fail with:
ctr: parent snapshot sha256:70798fd80095f40b41baa5d107fb61532bfe494d96313fea01e8fcbf4e8743ee does not exist: not found
My image was produced by buildkit, which doesn't unpack (I think this makes
sense since buildkit doesn't know if I am going to run the image or export/push
it etc).

Adds a useful flag to `ctr` to enable joining any existing Linux
namespaces for any namespace types (network, pid, ipc, etc.) using the
existing With helper in the oci package.

This changes the Windows runtime to use the snapshotter and differ
created layers, and updates the ctr commands to use the snapshotter and differ.
