This includes most things except the containerd and runc builds
which I will do next time I update them.
Note that all golang:alpine images now for 1.8 are ALpine 3.5 based.

The options added in de6e7f9cbe
were not applied for ntp configured servers.
As the address is always the same, stop using dhcp and just hard code this.
This should make sync work how it used to, ie quite well.
Also trust the GCP ntp server, as it is local and provided by infrastructure.

Set your daemon.json to something like:
```
{
"experimental": true,
"metrics-addr": "0.0.0.0:4999"
}
```
and your metrics will be at `localhost:4999/metrics`

After freeing the head of the perfstat block list, we must set it to NULL
to indicate that new blocks must be allocated. Previously, we risked
segfaults by trying to use a freed list.

This adds two new control channel requests, START_PERFSTAT and
STOP_PERFSTAT, that begin and end performance statistics collection
respectively. START_PERFSTAT takes the name of the mountpoint on which
to enable statistics collection and returns the current monotonic time.
STOP_PERFSTAT takes the name of the mountpoint on which to disable
statistics collection and returns the current monotonic time and the
message timings that have been collected.
Performance statistics are collected in a linked list of blocks. pthread
locks are used for synchronization.

This will potentially leave stuff in lost+found but may be able to
recover from more filesystem corruption.

Move to the development track of `containerd` not the legacy 0.2
branch. The commands have changed a bit.
This does increase the image size as we are bundling the Docker
copy and our copy, and the new one is larger as it is growing features.
Hopefully Docker will shrink eventually. Also we may replace `ctr`
with a library.
Fix#1029

Add basic database setup for AWS, GCP although these are not yet used
by the setup code but will be useful later.
Currently each is gated by `mobyplatform` but this can be removed once we
construct Moby per platform, and once these are containerised so they
are not run from `openrc`.

Previously we allocated `sizeof(struct ring) + size`. This patch
allocates `sizeof(struct ring)` and then `size` for the payload
separately. Hopefully the payload will be better aligned.

This patch adds a simple ring buffer implementation and uses it to buffer
the reads and writes to/from the AF_HYPERV socket and tap file descriptor.
This removes the need to perform small reads and writes for the per-packet
headers and allows a read on the Hyper-V socket to block at the same time
as a write to the tap device (and vice-versa)
The configuration in the init.d script is:
- a max message size (individual read or write) of 8192. Experimentally
this seems to be the largest completely reliable size across the Windows
versions we can support. Messages of length 16384 sometimes fail.
- a buffer size of 256KiB in each direction.
Single stream TCP throughput as measured by iperf increases modestly, by
another 100Mbit/sec.

In #1057 removed the 9p paths from the database mount
but that broke some users accessing them directly. Fix these.
