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.

-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.

Replaced SocketFlags.None (an enum which euqals 0) from zero.

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