Subject: 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).
