Add Masscan

[GoogleCodeExporter]

Evaluate adding Masscan to the Image. 
https://github.com/robertdavidgraham/masscan

While there are a number of port scanners on the image there are none quite 
this fast and flexible. It works wonders for things like CVE-2014-0160. Nmap 
detection was slow and painful while scanning our internal /8 (Think 
University), Masscan was able to tackle the /8 in 20 minutes while being rather 
successful at identifying bad hosts.

I know as an attack tool it's easily blocked/slowed down but I don't believe it 
is so wide spreed that many of the larger blocks are stopping it at this point. 
On a red team it's a quick picture of the attack surface.

It should be noted this tool has wide spread adoption in the world of higher 
education. 

What is the expected output? What do you see instead?
Masscan will become a default installed app.

it's not in Pentoo iso by default, but we have added to the overlay. You can 
just run "emerge masscan" and start using it.

1.) this bug is about do we want it on the live cd
2.) please stop forking gentoo ebuilds into the pentoo overlay.  remove masscan 
from pentoo and open a gentoo bug if you have any fixes.

I did not fork it for nothing. The bug report is opened for 2 years:
https://bugs.gentoo.org/show_bug.cgi?id=366609

Our fork supports that kernel module optionally.
