  Returns 0 if the candidate does not seem to be a URL.
  Returns 1 if it might be a URL, with the above pointers set to its pieces:
    service : [ // ] [ user [ : password ] @ ] host [ : service ] [ / path ] -
              [ ? name [ = value ]]

  Example: ftp://ds.internic.net:21/rfc/rfc1234.txt
    url.svc = [ftp]
    url.usr = [(NULL)]
    url.psw = [(NULL)]
    url.hos = [ds.internic.net]
    url.por = [21]
    url.pth = [rfc/rfc1234.txt]

  It might be a URL if it contains a possible service name followed by a
  a colon (:).  Thus "telnet:xyzcorp.com" is a minimal URL, whereas a
  full-blown example would be:

    ftp://olga:secret@ftp.xyzcorp.com/public/oofa.txt

  The caller must verify the results, i.e. that the service string is a real
  TCP service, etc.  This routine just parses the fields.
