[CCID 3]: New RX History Step 1 - Integrate data structure into CCID3
This is a `glue' patch to integrate the new RX history structure:
-- the `ccid3hcrx_hist' field is now present in rx_sock, but not yet used;
-- it obsoletes the {seqno,ccval}_nonloss fields (now in the history object);
-- the remainder is clerical - variable renaming for `last_counter'.
