dccp ccid-3: Remove ccid3hc{tx,rx}_ prefixes 

This patch does the same for CCID-3 as the previous patch for CCID-2:

        s#ccid3hctx_##g;
        s#ccid3hcrx_##g;

plus manual editing to retain consistency.

Please note: expanded the fields of the `struct tfrc_tx_info' in the hc_tx_sock,
since using short #define identifiers is not a good idea. The only place where
this embedded struct was used is ccid3_hc_tx_getsockopt().
