[Click] Click defines in ns3

Hi again,
Both for userlevel and linuxmodule click drivers, it is possible to set
defines for the click configurations with commandline options. The
attached patchset adds this ability to the ns3 click driver, too. It is
possible to set the defines for each click node within ns3 by
Ipv4ClickRouting::SetDefines (std::map<std::string, std::string> defines);
with defines being a key/value mapping for the defines to be set.
click-ns3-defines.diff is a small patch for click side, adding a new
function to create a click node instance with defines set.
ns3-nsclick-defines.diff adds support to the ns3 simulator side.
ns2 should still run without modification. It simply doesn't use the new
function, until someone provides a patch.
If this extension is interesting to you, please review the patch and
apply it if its ok.
Regards,
Sascha
