Consistently set RPCGEN_CPP when running rpcgen, so the C preprocessor
set via ${CPP} is used, instead of always using hardcoded /usr/bin/cpp.

MFC after: 1 week

The last big commit: let usr.sbin/ use WARNS=6 by default.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

$Id$ -> $FreeBSD$

Fixed missing dependencies on headers generated by rpcgen, as usual.
Removed bogus dependencies of generated .c files on generated headers.
Sorted sources lists.

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.

yppush_main.c:

- Remove unused 'pid' member from the jobs structure. (This was left over
from an earlier incarnation of the program that used multiple processes.)

- Remove #ifdef'ed longjmp() stuff.

- Print warning message if the 'pushing' host is not the master for
a map being pushed but don't bail out. (While yppush should only
be used on an NIS master, using it elsewhere is not an unpardonable sin.)

yppush.8:

- Fix a couple of mind-os.

Makefile

- Change format to hopefully ease bootstrapping. (Suggested by wollman.)
Other Makefiles should follow.

This commit was generated by cvs2svn to compensate for changes in r13394,
which included commits to RCS files with non-trunk default branches.

Import the new yppush.

This program does what the old one did, PLUS:

- Supports parallel jobs (like the SunOS yppush)
- Does everything in one proces instead of fork()ing off
children processes as callback listeners (this is done
using async socket I/O).
- Can be used to transmit maps to user-specified hosts.
- Has a much more verbose verbose option.
- Reuses existing code from ypserv and ypxfr.
- Uses some rpcgen-erated code as well.
- Isn't fattening. :)

Note that this is going in /usr/sbin rather than /usr/bin like
the old one. yppush is an administrative command it it's anything.
