Lock is evil.

This will actually affect the accuracy of GetDelta because
inboundDelta and outboundDelta may be calculated based on
the data collected at different time (eg. UpdateOutbound
get called before Interlocked.Read(ref _outbound)).

But that's not a problem. We can tolerate this little
inaccuracy. Besides, the _inbound, _outbound, _lastInbound
and _lastOutbound will be totally good because we use Interlocked.

At that time the remote even doesn't exist.
Also this debug output doesn't make any sense because when handling
udp request, this tcp connection won't have any meaningful data.
So I simply removed these two lines.

-Use dual-mode socket & DnsEndPoint to handle all domain name connection.
-Move all socket creation into one single function.

So that we could treat domain name just like ipv4 & ipv6 address.
This also solves the async domain solving problem because the os will
hanlde it for us.

Correct AvailabilityStatistics's behavior under special strategies like "LoadBalance", which may switch the server several times in a short period.
