This seems to be a difference between the AF_VSOCK and AF_INET
implementations. We work around it by exiting the proxy process
immediately, which will clean up resources anyway.

- don't try to create a `FileConn` because the Go library sees through
the scam and rejects it
- explicitly keep a reference to the `ctl` file just in case the GC
decides its dead and should be closed.

The port will be automatically removed when the fd/fid is closed by
a process exit/crash, or by a hypervisor crash.

The `NewProxy` function already knows how to deal with `net.UDPAddr`
and `net.TCPAddr`, this patch adds similar support for `vsock.VsockAddr`.
Signed-off-by: David Scott <dave.scott@docker.com>
This patch adds a wrapper around the `net.Conn` to include the
`CloseRead` and `CloseWrite` implementations. This patch also
exposes the `VsockAddr` type, which is similar to `TCPAddr` and
`UDPAddr`.

We require the frontend to be a `net.Listener` and the `net.Conn`
connection which are established must be type-switched to
`Conn` to support the `CloseRead` and `CloseWrite` methods.

The TCPProxy can proxy from anything which satisfies this interface:
type Conn interface {
io.Reader
io.Writer
io.Closer
CloseRead() error
CloseWrite() error
}

This package supports a more normal Go interface, in particular it has:
// Listen returns a net.Listener which can accept connections on the given
// vhan port.
func Listen(port uint) (net.Listener, error)

Note there is a slight name clash between the final binary 'proxy'
and the library formerly known as 'proxy'. Resolve this by calling
the library 'libproxy'.

- Trigger a CIFS mount by writing to the "cifsmount" key.
- The value has the format: <mountpoint>;<alias mountpoint>;<options>
with <options> containing username, password and optional domain
- The key is not stored in the KV store (aka the 'registry')
- Trigger an unmount by writing to the cifsumount" key.
- The value has the format: <mountpoint>;<alias mountpoint>
- The 'registry' is also wiped on reboot

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 makes fast shutdown work on Hyper-V
While at it, also clean up whitespaces. The file was mixed
tabs and spaces. Now it uses spaces.

If bonjour is installed on the host, e.g. via iTunes or some other
program, a lookup for `docker.local` works just like on the Mac.
Just like with LLMNR there seems to be a 4-5 second delay before
Windows decides to do a multicast namelook up, though

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
