This changes the CLI specification for disks, as it needs to be able to
be repeated.
```
linuxkit run qemu -disk name,size=1G,format=qcow2 ...
```
Options may be omitted.
Currently other local backends may not support multiple disks, but this
can be added in future. Code for cloud backends has not changed as the
disk support is specific to the platform.

This ovmf package is part of the community repository. We don't
want to "pollute" the Alpine base with it. Luckily it's juts a single
file which we can install and then copy to the base image.
The package is needed for qemu EFI boot.

This should make it easier to switch out `init` for other versions,
although the `getty` config still needs to be removed.
- use `/bin/rc.init` for start
- use `rc.shutdown` for stop
- make `rc.init` run other code.
- merge `containers` and `containerd` startup code

We don't actually build it here, we just use the alpine package, which is
already included in the linuxkit/alpine base.
Can be instantiated with a service stanza such as:
- name: qemu-ga
image: "linuxkit/qemu-ga:e5fbcf55926f6e1a96b3e49a392e547e8be1022c"
binds:
- /dev/vport0p1:/dev/vport0p1
The only functionality I've tested is to report IP addresses to the host (e.g.
via `virsh domifaddr`).
The image is configured to use `/dev/vport0p1` by default. If your VM image is
using a different port number then you can either incorporate the rename into
the bind ("/dev/vport1p1:/dev/vport0p1") or override the command with:
command: ["/usr/bin/qemu-ga", "-p", "/dev/vport1p1"]
The mdev tool appears to not create the symlinks which udev would provide
`/dev/virtio-ports/org.qemu.guest_agent.0` hence the need to hardcode the
potentially unstable `/dev/vportNp1`, `N` seems to depend on the number and
order of virtio devices in use. I don't know if it is possible to get mdev to
create these links. For reference the udev rule is:
SUBSYSTEM=="virtio-ports", KERNEL=="vport*", ATTR{name}=="?*", SYMLINK+="virtio-ports/$attr{name}"
See https://wiki.libvirt.org/page/Qemu_guest_agent for more info on the guest
agent.
A suitable stanza is added to `projects/swarmd/swarmd.yml` since that is where
I am using it.

Adds a new --networking option to simplify selection of networking modes
for `linuxkit run hyperkit`. The new modes are "docker-for-mac",
"vpnkit" and "none".
By default docker-for-mac will be used for networking. HyperKit will
then connect to the default VPNKit socket location used by Docker for
Mac.
In vpnkit-mode a new VPNKit instance is started and the socket
"vpnkit_eth.sock" is created in the state directory. This mode also
enables port forwarding via 9p and vsock. The vpnkit mode optionally
accepts a path to an existing VPNKit socket. This allows two or more VMs
to be connected to the same virtual network - but only the VM that
created the the socket can use port forwarding.
Mode "none" disables networking.

This test check that the link is up, that we got a IP address
and the output of the dhcpcd daemon.

Don't rely on systctl test package. Instead, add the check shell
script to the image and execute it with a standard Alpine image.
While at it, make the test more verbose.

Use the index in the alphabet (a=1...) to group the tests
a little bit. The actual order does not matter.

While not used anywhere, adding it to the based makes it easy
to add temporarily add it to init (or elsewhere) for debugging.
