missing short options (`F:' and `Z:' for example)
ipinfo update

1) now `y' and `z' keys work when MTR is started without `y' or `z' option

  for example: start mtr then press `y' ...

2) `y/ipinfo' option can accept multiple values

  syntax:
    -y/--ipinfo origin,fields

  examples:

    origin.asn.spameatingmonkey.net: CC, ASN, ORG
    % mtr -4t -y3,5,2,3 hostname

    origin.asn.cymru.com: ASN
    % mtr -4t -y, hostname
New mode added: graphcairo (alpha version)

To build mtr with graphcairo you need to install -
  cairo pango xcb xcb-keysyms cairo-xcb

then, for example
% ./bootstrap.sh
% ./configure --with-graphcairo --without-gtk
% make
% ./mtr -G, hostname

1 - small code cleanup, 2 - waittime and first TTL issue

2:
for example:
  mtr -f16 japan-guide.com

In my case,
  numhosts 17 and intervaltime ~60 msec (ping ~150msec in my case)
  but actually hosts 2 only (i.e. intervaltime must be 500 msec).

  In the result the last ping is always -1 ('?' in display mode).

fix:
 If the socket is connected, getpeername() will return 0.
 Else getpeername() will return ENOTCONN, and read(,,1) will produce the right errno.
 This is a combination of suggestions from Douglas C. Schmidt and Ken Keys.
