Implementation of UDP server and client under Windows

UDP is a non-connected protocol, so when implementing a UDP server, the server is not always in the listening state. You can send and receive data directly.

4. Send and receive Data recvfrom (..) SendTo (..)
5. Close the connection and release the resource closesocket (..) WSACleanup ()
Client//No binding required
