EAFNOTSUPPORT likely means we are running on a hypervisor which doesn't support
that particular socket type.

- try several wget's on well known IP addresses to check IP
connectivity (ping in hostnet mode is not good enough)
- try DNS lookup on a well known server
- add service-port-opener logs

The Windows start script polls the VM for it's IP address before
initiating things like CIFS mounts. Getting the IP config is
done via the KVP daemon. Starting it earlier reduce the start up
delay, in particular if the VM is part of a swarm.

This allows the proxy to be run easily from a terminal or other script
without requiring fd 3 to be open and writable.

This tells start-stop-daemon to run tap-vsockd as a daemon, and tells
tap-vsockd not to daemonize itself. This seems to work more reliably
than when tap-vsockd self-daemonizes.

The existing `ntp=gateway` cmdline support overrides this, but is largely
redundant now.
A DHCP derived server will not be given the "trust" directive in the
configuration file, since it is harder to argue that we know we should trust a
server which arrives this way since it depends on the context in which Moby is
running. It's not clear to me that it makes much difference anyway.
This only uses the first server in $ntpsrv, since Piñata will only provide one
and supporting more makes the sed quite a bit more complex.
If `ntp=gateway` is given then we now use $router instead of parsing IP output.

Linux xargs calls the command with no arguments if it gets no inputs, which
`docker rmi` complains about. It provides -r / --no-run-if-empty to prevent
this but unfortunately this isn't supported on OSX.
Ignore errors from `docker rmi` so that `make clean` will keep going and clean
up later stuff.

Reconfigure chronyd in a udhcpc post-bound hook and restart it, but use
conditionalrestart so it is not started if it isn't running, which is the case
during boot when this hook happens from init.d/networking via ifup, running
"service ... start" in that context results in the daemon running but the
service db saying it isn't.
Doing it in the udhcpc hook leaves a nice hole where support for getting the
NTP server via DHCP can fit in once it is available.
This also switches from using "initstepslew" to "makestep", the former was
responsible for the long delay starting chronyd (meaning we can now drop
"before chronyd" from Docker's init dependencies), while the later will force a
step if the time is out by more than the configured amount (half a second
here), meaning it will be corrected on resume. The rest of the time it chrony
will do the usual slewing to keep the clock accurate. Passing -1 as the limit
to "makestep" ensures the step will always occur, if it were positive it would
only be done that number of times.
We add "iburst" and "minpoll 2" to the default configuration file to speed up
initial sync and resync after sleep respectively, resync after sleep happens in
a couple of seconds. In "ntp=gateway" mode we also patch in "trust", this isn't
in the default config file since we won't be so sure about DHCP provided
servers, but when talking to a host provided NTP we want to use its time (for
sync accross host mounts) even if it has a crazy idea about what the time is.
With this we can also remove the 15min ntp sync, which in turn gets rid of the
need for cron.
