Alan Somers fac7bc2365 Serve /etc/eui64 via NIS.
The C library already knows how to lookup eui64 entries from NIS. For
example, fwcontrol(8) does it. But /var/yp/Makefile.dist doesn't build the
eui64 maps, and ypinit(8) doesn't push them to slaves. This change fixes
that.

The `-m' flag builds a master YP server, and the `-s' flag builds
a slave YP server. When building a slave YP server, `master_server'
must be an existing, reachable YP server.
The `-u' is for updating the ypservers map on a master server.
