ncurses: chase dependency changes in the source tree

Differential Revision: https://reviews.freebsd.org/D32098

Don't link against libdialog/ncurses when bootstrapping tzsetup

Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones

This simplifies pathing in make/displayed output.

Fix build of tzsetup when WITHOUT_DIALOG is set

Hide dialog specific code behind HAVE_DIALOG. It allows to build a stripped
down version (missing the dialog UI) but perfectly function tzsetup when
world is built WITHOUT_DIALOG

Reorganise a bit the code to limit the number of blocks under HAVE_DIALOG

Convert usr.sbin to LIBADD
Reduce overlinking

Revert r261296. This removes the WITHOUT_NCURSESW option.

It was the wrong direction. We will instead remove use of the
non-wide-character supporting libncurses.

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

Add an option WITHOUT_NCURSESW to suppress building and linking to
libncursesw. While wide character support it useful we'd like to
only need one ncurses library on embedded systems.

Port to new libdialog.

Update dialog to version 20100428. This changes the license under which
dialog is distributed from GPLv2 to LGPLv2 and introduces a number of new
features and a new and better libdialog API. The existing libdialog will
be kept temporarily as libodialog for compatibility purposes until sade,
sysinstall and tzsetup have been either updated or replaced.

__FreeBSD_version is now 900030.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

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

- Import the HEAD csup code which is the basis for the cvsmode work.

style.Makefile(5)

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.

Remove -Wall. It breaks compiling with non-gcc compilers.

This builds fine with -Wall.

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

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

Remove unneded -lmytinfo

Re-add the libmytinfo/libncurses stuff - removing it breaks static
linkage.

Pointed out by: bde

The libraries `libmytinfo' and `libncurses' are not required by this
program.

$Id$ -> $FreeBSD$

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.

Completely re-vamped `tzsetup':

- It no longer attempts to fiddle wall-vs-UTC-in-RTC. The results
were just confusing most of the time.

- The program no longer contains a pre-compiled list of timezones
(compiled by groveling through the tzdata source files for comments
starting with `ZONE-DESCR'). Now it uses the new `zone.tab' file
supplied with current versions of the timezone data files, to determine
the list at run time. (It also requires the ISO 3166 table I
committed some months ago.)

AS A RESULT, this program will NOT work until the new timezone data files
are committed (should happen sometime soon).

Removed unused `-I.'s from CFLAGS.

"." means the object directory, so it is just confusing to use it
when nothing is included from the object directory unless the object
directory is also the source directory. It is confusing for "."
not to mean the source directory anyway, so used `-I.'s should be
replaced by `-I${.OBJDIR}'.

add a manpage

Grand new all-singing, dialog-wielding tzsetup(8). Still needs a man page.

A little script to help users in setting up their timezone. (Try it!)
