Microsoft.AspNet.Server.Kestrel.Http.Listener ignores host argument

[srdjantot]

Listener always binds to IPAddress.Any host. This can lead to problems when security policy allow only specific IP to bind to.

Are there any reasons for listener to ignore supplied host argument?

public Task StartAsync(
            string scheme,
            string host,
            int port,
            KestrelThread thread,
            Func<Frame, Task> application)
        {
            Thread = thread;
            Application = application;

            var tcs = new TaskCompletionSource<int>();
            Thread.Post(_ =>
            {
                try
                {
                    ListenSocket = new UvTcpHandle();
                    ListenSocket.Init(Thread.Loop, Thread.QueueCloseHandle);
                    ListenSocket.Bind(new IPEndPoint(IPAddress.Any, port));
                    ListenSocket.Listen(10, _connectionCallback, this);
                    tcs.SetResult(0);
                }
                catch (Exception ex)
                {
                    tcs.SetException(ex);
                }
            }, null);
            return tcs.Task;
        }

Looks like a bug to me

Allow binding to IPs or *.
If localhost is requested, bind to 127.0.0.1 and ::1.
If any other host is requested bind to *.
For *, bind to both IPv4 and IPv6.

I think this is a dupe of #57. Should we close one of these issues?

Taken care of.
