On a Hyper-V system we can only register one listening endpoint (with
a GUID), so we need to accept connections, read a header and then
start the proxy.
If the binary has argv[0] == "proxy-vsockd" then run this new frontend.

The tap-vsockd service is started from eth1's pre-up script.
On the Mac: the bind of the AF_HYPERV socket fails, and eth1 is skipped.
On Windows: if there is no database then eth1 is skipped.
On Windows: if the database has network=native then eth1 is brought up.

This will make it easier to add a vsock interface as well as a regular
TCP/IP one.
As a side-effect, the server is now able to handle more than one concurrent
request!

This is a bit ugly as we copied and then modified the chronyd init.d
script as shipped in the package.

- Don't start hv_fcopy_daemon. It seems to exit and we are not
using it anyway. Also, remove it from the initrd
- Move hv_kvp_daemon and hv_vss_daemon to start earlier
(before networking and docker being started)

LLMNR is the Windows equivalent of mDNS.
Import the LLMNR daemon from https://github.com/tklauser/llmnrd
It needed some small modification to compile cleanly on Moby
LLMNRD is only started when running inside a Hyper-V VM

These are WIP taken from git@github.com:stefanha/linux.git#vsock
(==4c9d2a6be1c6, using "cherry-pick -x") and correspond to RFC v5 of the
frontend patches posted in
http://thread.gmane.org/gmane.linux.kernel.virtualization/27455
There is no corresponding spec proposal update yet, but this set of patches
correspond (roughly) to addressing the feedback on v4 of the spec proposal
http://thread.gmane.org/gmane.comp.emulators.virtio.devel/1062.
kernel_config.arm modifications copied from x86, not tested.
Added /etc/kernel-patches/ directory to the image to be consumed by the
licensing.

A client like `pinata diagnose` can do the equivalent of:
nc 192.168.64.2 62374 > foo.tar
and find `foo.tar` contains
- the output of `/usr/bin/diagnostics`
- `iptables -L`
- `netstat -an`
- `ps uax`
- `docker ps`
- `dig docker.com`
- `wget http://docker.com`
This will allow us to diagnose various in-VM faults, without having
to ask the user to access the console and run commands.

The busybox adduser and addgroup commands are ignored by docker,
as it avoids symlinks, but they are not compatible so this is
kind of a good idea.
See https://github.com/docker/docker/blob/master/pkg/idtools/usergroupadd_linux.go
However, these do not yet deal with creating mapping ranges in /etc/subuid and
/etc/subgid, so initially we provide a set that match the default docker name
so at least docker daemon --userns-remap=default should work.

The daemons allow proper shutdown of a VM, heartbeats,
inquiring and setting the network configuratio etc etc.
They are only started with running in a Hyper-V VM
