NG special for Kirby

Hi,

Many improvements again in this release :

- thanks to Gisle Vanem, win32 support is on a good way!

- add support for IP and TCP options : this is done through a shared
  structure (see libnet_opt_hdr in libnet_headers.h) and builders
  (a generic one, and specific for each kind of options, see
  libnet_build_[ip|tcp].c
  Have a look at tcp1.c and udp1.c

- add another granularity level for the builder: you can use macro à
  la dnet to "pack" headers (see in libnet-functions.h)

Kirby, isn't that (almost) what you ever wished ;-)
