newkey(8): fix 'tmpname' memory leak (always) and input file descriptor leak
when output file cannot be opened

PR: 201732
Reported by: David Binderman <dcb314@hotmail.com>
MFC after: 1 week

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.

Revert most part of 200420 as requested, as more review and polish is
needed.

Remove unneeded header includes from usr.bin/ except contributed code.

Tested with: make universe

Fix compilation of newkey(8) with WITHOUT_NIS=yes.

Increasing WARNS seems to have broken compilation of this utility.
Instead of lowering WARNS, just fix to code to compile properly.

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

Avoid usage of implicit int.

ANSIfy, VCS inclusions and some very minor style.

remove __P

WARNS=2 fixup.

Turn on YP (NIS) while I'm about it.

Fix the type of the NULL arg to execl()

Idea from: Theo de Raadt <deraadt@openbsd.org>

$Id$ -> $FreeBSD$

Calls one or more of malloc(), warn(), err(), syslog(), execlp() or
execvp() in the child branch of a vfork(). Changed to use fork()
instead.

Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

Replace incomplete malloc prototype with #include <stdlib.h>
to get the proper one.

Add usage(), use err(3).
Rewrote man page in mdoc format.

Import newkey.

This is the program used to generate new Secure RPC public and secret
key pairs.
