184fa38903 diagnostics: listen on both TCP/IP and vsock ports 
The TCP/IP port will be used by Windows, while Mac can use the vsock
one.

4802911c8f moby: rewrite diagnostics server in Go 
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!

18e54b792b diagnostics: apply a timeout to all commands 
This should avoid unnecessary blocking if (for example) the network is
down.

The extra `-t nat` includes the masquerading stuff.

af9b3ad7a2 Allow diagnostics to be downloaded on port 62374 
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.
