- ENA networking is what the very new (and bare metal) machines have
- sriov "simple" mode is Intel VF passthrough
I reflect the underlying APIs, which is bool for ENA and a string
for sriov even though there is currently only one valid sriov option...

Currently we will always create a temp tar file even the 'docker run'
failed for some reason,e.g, the docker daemon doesn't run. As a result,
we'll get the 2nd error even we've fixed 'docker run' failure.

This is a `moby.ImageConfig` struct which is marshalled into JSON and added as
the `org.mobyproject.config` label on the built image.
Convert `pkg/sysctl` as PoC.

The update in 6ede240737 ("kernel: Update to
4.14.1/4.13.15/4.9.64/4.4.100") failed to build on aarch64.
This fixes it.

If doing the build separately from pushing (as I am intending in
https://github.com/linuxkit/kubernetes/pull/8/) it is desirable to avoid a
second build when pushing.

For 'build_perf_' and 'build_zfs_' targets in the Makefile,
since both of them are dependends on the build_$(2)$(3) target,
So, we pull the image with DCT as part of the dependency on build_$(2)$(3)
and then build with DOCKER_CONTENT_TRUST explicitly set to 0.

The PR adding cadvisor overlapped with the kernel updates. This
brings the example back in line.

Also add libelf-dev as this is needed for ORC_UNWINDER. While this is only
a feature of 4.14.x we added it to all Dockerfiles to keep things in synch.

REFCOUNT_FULL enables full reference count validation. There is a
potential slow down but ti protects against certain use-after-free
attacks.

On 4.13 and 4.14 kernels GCC_PLUGIN_RANDSTRUCT can be use to randomise
some kernel data structures such as structs with function pointers.
We also select GCC_PLUGIN_RANDSTRUCT_PERFORMANCE which
tries harder to restrict randomisation to cache-lines in order to reduce
performance impact.

The 4.13 and 4.14 kernels support GCC_PLUGIN_STRUCTLEAK, a GCC plugin
to zero initialise any structures with the __user attribute to prevent
information exposure.
On 4.14 kernels also enable GCC_PLUGIN_STRUCTLEAK_BYREF_ALL which is
an extension of the above
