Implement UDP/IP wrapper objects.

[aregtech]

Implement support of UDP/IP communication channel, integrate in communication manager.
Goal:

• Currently AREG SDK supports TCP/IP protocol and it should support as well UDP.
• The protocol configuration is defined in file router.init

Motivaton:

• As an alternative to TCP/IP and as a fast communication, AREG SDK should support UDP.
• There will be a new example of testing data rate by switching between protocols, developers may make test protocols and choose one, which is more suitable for their projects.

Background information:

• The TCP/IP implementation (wrapper) is defined in NESocket.hpp. The sources are implemented separately for the POSIX and Win32.
• The Socket.hpp class is generic object for TCP/IP, SocketServer.hpp, SocketClient.hpp and SocketAccepted.hpp are appropriate objects for communication.
• Similar to this, there should be wrappers of UDP.

When the objects are ready, there will be refactoring of IPC, so that depending of configuration the application will decide whether to use TCP/IP or UDP channels.
