ndppd: initial import (release 0.2.1)

Hi,

here is a patch to add a package for ndppd:

    ndppd, or NDP Proxy Daemon, is a daemon that proxies NDP (Neighbor Discovery
    Protocol) messages between interfaces.  ndppd currently only supports
    Neighbor Solicitation Messages and Neighbor Advertisement Messages.

    The ndp_proxy provided by Linux doesn't support listing proxies, and only
    hosts are supported.  No subnets.  ndppd solves this by listening for
    Neighbor Solicitation messages on an interface, then query the internal
    interfaces for that target IP before finally sending a Neighbor
    Advertisement message.

I tested it and it works fine.  I am willing to maintain it.

Note that this my first C++ package and it took a lot of trial and error to get
the Build/Compile target working.  Any feedback would be much welcome.

Best regard,
