move another two capture related fields (iface and cfilter) from cfile to capture_opts also move the handling of capture related command line options from main.c to capture.c, that way a future privilege seperated capture program can use the same code to parse it's command line than Ethereal. It might be even possible to share this parser code even with Tethereal, didn't took a closer look at this. svn path=/trunk/; revision=13320
