Added functionality for UDP/TCP/SCTP transferring of data over the ASYNC channel interface.

Browse Source 
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";
    };
