lib: Changes to du_buff structure

du_buff.c : Will now allocate memory only upon init, not upon create.
            User can add compiler flag DU_BUFF_BLOCKSIZE to set the
            size of a du_buff memory block.  If the size for the
            du_buff is larger than DU_BUFF_BLOCKSIZE, the du_buff will
            be structured as follows:

            HEAD -> DATA_BLOCK -> ... -> DATA_BLOCK -> TAIL

            HEAD and TAIL are contiguous and may be larger than
            DU_BUFF_BLOCKSIZE if required.
