Apply the following mechanical transformations in preparation for
ansification and constification:

s{\s+__P\((\(.*?\))\)}{$1}g;
s{\(\s+}{\(}g;
s{\s+\)}{\)}g;
s{\s+,}{,}g;
s{(\s+)(for|if|switch|while)\(}{$1$2 \(}g;
s{return ([^\(].*?);}{return ($1);}g;
s{([\w\)])([!=+/\*-]?=)([\w\(+-])}{$1 $2 $3}g;
s{\s+$}{\n};g

Also add $FreeBSD$ where needed.

MFC after: 1 week

change callrpc() from taking "char *" args, I'm quite sure they really meant
to use "void *".

remove a duplicate prototype for callrpc() from libexec/ypxfr/ypxfr_extern.h

$Id$ -> $FreeBSD$

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Change declaration of yp_errno from int to enum ypstat so that it
matches what's in ypserv/yp_extern.h (which I changed when I added the
async DNS stuff). The conflict broke the build of rpc.yppasswdd.

Give ypxfr the ability to detect the presence of the YP_INTERDOMAIN
and YP_SECURE flags so that it can properly add them to newly created
maps when needed. This applies only when using the 'standard' method
for map transfers. When using rpc.ypxfrd, the whole map is copied
verbatim, along with any special entries that may be encoded in it.

Also made -Wall a little quieter for ypxfrd_getmap.c.

Add support for rpc.ypxfrd and document it in the man page.

Also generallize the yp_dbwrite functions a little: allow the caller
to specify certain flags. I need this mostly for some changes to
rpc.yppasswdd to allow in-place updates.

Also change Makefile a little to use the same format as ypserv.

This commit was generated by cvs2svn to compensate for changes in r13007,
which included commits to RCS files with non-trunk default branches.

Import the new ypxfr, written by yours truly. Functionally equivalent
to the old one, except that it supports an additional option (-p path)
that lets you specify the top level path wiere your NIS maps live.
(ypserv allows you to specify a path like this, so it makes sense that
ypxfr should too. ypserv will automagically pass the -p flag to ypxfr
if you use a path other than /var/yp when you start it.)

This program uses client stub code generated by rpcgen as well as
the yp_dblookup.c module from ypserv.
