This patch fixes two problems caused by the ubiquitous long "hctx->ccid2htx_" and "hcrx->ccid2hcrx_" prefixes: * code becomes hard to read; * multiple-line statements are almost inevitable even for simple expressions; The prefixes are not really necessary (compare with "struct tcp_sock"). There had been previous discussion of this on dccp@vger, but so far this was not followed up (most people agreed that the prefixes are too long).
