New port: mcl

[Panagiotis Astithas]

Hi,

I have submitted a port (ports/58728) of mcl (http://www.inrialpes.fr/planete/
people/roca/mcl/mcl.html), an implementation of Reliable Multicast Protocols. 
To quote from pkg-descr:

The MCLv3 project is an Open-Source GNU/GPL, multi-platform
implementation of the two major reliable multicast protocols being
standardized by the RMT IETF working group: ALC/LCT and NORM. It is
composed of a C/C++ library and several applications built on top of it
and provides an easy-to-use and integrated solution for reliable and
highly scalable multicast delivery of data.

It gets a clean pass from portlint. I would be grateful if someone would 
review and commit it.

Regards,
