Add a ypinit script and man page (script lifted from OpenBSD and haqued

to work on FreeBSD, man page written by me.)

Also change Makefile.yp a little to be more tolerane in the face of
missing source files. Print a message if we can't find /var/yp/master.passwd
telling the user what to do to fix things.

+.Sh NAME
+.Nm ypinit
+.Nd build and install NIS databases
+.Sh SYNOPSIS
+.Nm ypinit
+.Fl m
+.Op Ar domainname
+.Nm ypinit
+.Fl s
+.Ar master_server
+.Op Ar domainname
+.Nm ypinit
+.Fl u
+.Op Ar domainname
+.Sh DESCRIPTION
+The
+.Nm
+script sets up databases on a Network Information Service (NIS)
+master or slave server.
+.Pp
+On a master server,
+.Nm
+creates the
+.Pa /var/yp/$DOMAINNAME
+directory, the
+.Pa /var/yp/ypservers
+file, and calls
+.Pa /var/yp/Makefile
+to create and populate an initial set of NIS maps. The maps are
+created from local source files using the
+.Xr yp_mkdb 8
+command. The script will prompt the user for a list of servers
+that support the specified domain; this list is used to populate
+the ypservers map.
+.Pp
+On a slave server,
+.Nm
+creates the
+.Pa /var/yp/$DOMAINNAME
+populates it with copies of the NIS maps from the master. The maps
+are obtained from the master using the
+.Xr ypxfr 8
+command. The
+.Nm
+script obtains the list of maps to transfer in one of two ways: if
+the system is configured as an NIS client and is bound to the master
+server,
+.Nm
+is able to use the
+.Xr ypwhich 8
+command to obtain a list of maps exported by the master server.
+If the system is not configured as a client of the NIS master,
+.Nm
+uses a hardcoded list of maps, some of which may or may not actually
+exist on the master. The system administrator can edit the script and
+modify the map list if necessary. Otherwise, indivudual maps can
+be transfered manually from the master using
+.Xr ypxfr 8 .
+.Pp
+.Sh OPTIONS
+.Nm
+supports the following options:
+.Bl -tag -width Fl
+.It Fl m Op Ar domainname
+Set up a master server. By default, the script sets up a server for
+the system default domain. The user can override this default by specifying
+.Ar domainname
+explicitly.
+Maps are constructed from scratch using local files as templates using
+the
+.Xr yp_mkdb 8
+command.
+.It Fl s Ar master_server Op Ar domainname
+Set up a slave server using
+.Ar master_name
+as the master. Maps are copied from
+.Ar master_server
+to the slave using
+.Xr ypxfr 8 .
+By default, the script sets up a server for
+the system default domain. The user can override this default by specifying
+.Ar domainname
+explicitly.
+.It Fl u Op Ar domainname
+Update the ypservers map on the master server. When a new slave
+server is added to a domain, its hostname must be added to the
+ypservers map so that
+.Xr yppush 8
+can propagate updates on the master to all of the slaves.
+.Sh FILES
+.Bl -tag -width /var/yp/master.passwd -compact
+.It Pa /etc/bootparams
+Bootparams source file
+.It Pa /etc/ethers
+Ethers data source file
