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(). Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
