[Xymon] Xymond and xymonnet quirks

[Steve Holmes]

We just ran into this same problem and removing the 'dns' tag from one DNS
server (non-production) which wasn't working reduced the time to do the DNS
tests from over 300 seconds to 22. This was after already tuning the
options on the xymonnet call.

Also, WRT the unknown option --timelimit, we think that in (4.3.7)
xymonnet.c starting at line 2011:

    else if (strcmp(argv[argi], "--timelimit=") == 0) {
      char *p = strchr(argv[argi], '=');
      p++; runtimewarn = atol(p);
    }
    else if (strcmp(argv[argi], "--huge=") == 0) {
      char *p = strchr(argv[argi], '=');
      p++; warnbytesread = atoi(p);
    }

Both of the strcmp calls should be argnmatch. The second one is for a
different option, of course, but it probably would get the same error
without this fix. Note, I haven't tested this, but I'm pretty confident
that it is right.
