New port - mpd-l2tp-ipv6pd-client

A sample implementaiton set of "L2TP-IPv6PD" client using mpd.
"OCN IPv6", provided by NTT Communications Corp, was the first
commercial tunnel service using "L2TP-IPv6PD".

NOTE: This port runs on FreeBSD 6.3 and later.  If you want to run it
on FreeBSD 6.2, you need to apply following diff to your ng_ksocket:
