MFC r264400,r265836:

r264400:

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

r265836:

Remove last two NO_MAN= in the tree. In both of these cases, MAN= is
what is needed.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Rever the previous changes. It turns out that it perfectly correct
for a makefile to set 'NO_MAN=' when the makefile is for a program
that will not create a man page.

Based on reaction from: ru bde

Switch these makefiles to use 'MAN=' to indicate they will not generate
a man page, instead of 'NO_MAN='. 'NO_MAN=' is something users would
set, not something a makefile should be using.

Based on comments by: des

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

For variables that are only checked with defined(), don't provide
any fake value.

More changes to use __FBSDID() for setting rcsids. For the filter
programs, minor Makefile changes are needed to find lp.cdefs.h.
For lpf.c, the 'sccsid' line is formatted to match style(9), and
a 'From:' is removed so the sccsid returns to what it was back
in the days of '-r CSRG' (1994).

We don't need two $FreeBSD$'s. Remove the older one.

Include stdlib.h for atoi declaration.
Add $FreeBSD$ while I'm here.

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.

Add koi2855 filter
