Nikos Makris 9db40696f7 Added functionality for UDP/TCP/SCTP transferring of data over the ASYNC channel interface. 
Added selection of interfaces through the configuration file with a new block of statements as follows:

    FLEXSPLIT_INTERFACES :
    {
        DU_INTERFACE_NAME_FOR_F1U           = "lo";
        DU_IPV4_ADDRESS_FOR_F1U             = "127.0.0.1/24";
        DU_PORT_FOR_F1U			    = 2210;

        CU_INTERFACE_NAME_FOR_F1U           = "lo";
        CU_IPV4_ADDRESS_FOR_F1U             = "127.0.0.1";	//Address to search the DU
        CU_PORT_FOR_F1U			    = 2210;

        // One of TCP/UDP/SCTP
        F1_U_TRANSPORT_TYPE 		    = "UDP";
    };

Nikos Makris 2eb2b5e7ba First working version of the DL split. 
TODO list:
1) check the message handler as if the function is not present it does not return msg not handled
2) use and check return arguments from the functions calling the data req
3) parse the config file for the configuration arguments
4) clean up the messy code
5) define and use other protocols than TCP for the communication between RLC and PDCP
