Teach an IPV6CP to pppd(8).
The eui64.[ch] and ipv6cp.[ch] were taken from ppp-2.3.11. However, our stock pppd(8) doesn't provide option_t nor some utility functions. So, I made some hacks to adjust to our stock pppd(8). The sys_bsd.c part was taken from NetBSD with some modifications to adjust to our stock pppd(8). MFC after: 1 week
