update netcat 1.12 to 1.13

update netcat 1.12 to 1.13

why?

modify by  2013/04/30

netcat -C ip port same as netcat -L -p port

how to update:

-   while ((x = getopt (argc, argv, "ade:g:G:hi:lLno:p:rs:tuvw:z")) != EOF) {
+   while ((x = getopt (argc, argv, "aCde:g:G:hi:lLno:p:rs:tuvw:z")) != EOF) {

+            case 'C':                /* connect then cycle back to start instead of exiting */
+      cycle = 1;
+      break;

#ifdef WIN32
    WSACleanup();
#endif

      if (cycle == 1)
        goto recycle;

changed to：

      if (cycle == 1)
        goto recycle;

#ifdef WIN32
    WSACleanup();
#endif
