Go commit https://github.com/golang/go/issues/23672 introduced a
whitelist ofr flags passed into gcc to prevent arbitrary code
execution (CVE-2018-6574). The x86 rngd code uses two CFLAGS
not on the whitelist. Add them to 'CGO_CFLAGS_ALLOW'.

Without the privileged flag, the tcsd daemon does not have
access to the mounted host device files, especially the tpm
device file.

We already had this increased above the defaults, but even larger values
seem to be recommended.

"It’s common to tune this setting in HPC clusters, and is particularly
relevant in Kubernetes clusters since every pod has its own IP address
which consumes space in the ARP cache."

This package is primarily for users of custom or foreign
kernels which may have drivers enabled for which the
'firmware' package does not contain the firmware blobs.

This new 'firmware' package contains the firmware blobs required
by the device drivers in a LinuxKit kernel. The list of required
blobs is determined by calling 'modinfo' on each module.
We also unconditionally include the AMD CPU microcode and the
licence files.

This is similar to ae64ab6b82 from #2849 which
did the same for runtime.mkdir.
This makes it possible to specify both host (absolute) or container (relative)
paths.

This PR correctly plumbs a single context to propagate the containerd
namespace to the necessary commands. Services launched with containerd
after this change will now be in a default namespace of
`services.linuxkit`.
A top-level flag is added to the service command,
`--containerd-namespace` which can be used to change, if needed.

Use unix.Reboot from golang.org/x/sys/unix for poweroff and reboot
instead of relying on external commands.

- Previously, KV lines which were commented would attempt to be set. Now any commented KV lines will also be ignored.
- Comments can start with a hash or semicolon
- Splitting KV on both period and forward slash
- Some kernels may not have certain features enabled (such as IPv6) in the default etc/sysctl.d/*.conf, and thus pkg/sysctl would only set the KV until the first failure, and then silently skip the rest of the KVs. Now any failure is logged as a WARN, and those lines can now be commented per the above change, as they will be identified.

This was added to alpine since our package was created. Now we have upgraded we
can just use the binary.
The package contains an auditd.conf but we have a tweak local copy which writes
to stdio (which goes to /var/log/auditd.*.log already). The package doesn't
have an audit.rules so keep that here too.

containerd v1.0.0-rc.0 changed the subreaper config entry to the
negative given subreaper "on" is the default. However, linuxkit
does not need to change the default subreaper setting so removing
the now invalid config line.

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.
