spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

Make ppp(8) buildable.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

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.

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

Make ppp WARNS=5 clean

Remove whitespace at the end of lines.

NetBSD keeps des.h in /usr/include/openssl these days

Change copyright to BSD-style copyright.

Staticise the OpenBSD SHA1_End() function

When we change the interface MTU, run through the routing table and tweak
all route MTUs too.

Use only the bit after the ``\'' when hashing the challenge in
MSChapv2

Merge some OpenBSD/NetBSD fixes to the recent MPPE/CHAP0x81 update.

Various whitespace changes.
Make some functions static.

Add MPPE and MSChap v2 support (denied and disabled by default)

Submitted by: Ustimenko Semen <semen@iclub.nsu.ru>

Adjust whitespace

Use libcrypto instead of libdes.

$Id$ -> $FreeBSD$

Fully support both NT and LANMan CHAP type 0x80 as both
authenticator and authenticatee.

Cosmetic: Make our external function names consistent.

Remove unused includes.

Move `CleaningUp' into struct bundle.

This commit was manufactured by cvs2svn to create branch 'MP'.

Remove unused #includes.
Make various bits static.
Remove unused variables.

Cosmetic (style):
sizeof(var) -> sizeof var
sizeof type -> sizeof(type)

Suggested by: J Wunsch <j@uriah.heep.sax.de>

Fix prototypes.
Remove extraneous decls.
Add ``const'' to several places.
Allow ``make NOALIAS=1'' to remove IP aliasing.
Merge with OpenBSD - only the Makefiles vary.

We can now survive a compile with
-Wall -Wbad-function-cast -Wcast-align -Wcast-qual
-Winline -Wmissing-declarations -Wmissing-prototypes
-Wnested-externs -Wpointer-arith -Wredundant-decls
-Wshadow -Wstrict-prototypes -Wwrite-strings -Wchar-subscripts
(although the Makefile just contains -Wall).

Cosmetic (no functional changes):
o Add missing $Id$s
o Move extern decls from .c -> .h files
o Staticize
o Remove #includes from .h files
o style(9)ify includes
o bcopy -> memcpy
bzero -> memset
bcmp -> memcmp
index -> strchr
rindex -> strrchr
o Move timeout.h -> timer.h (making it consistent w/ timer.c)
o Add -Wmissing-prototypes

Do the MSChap encryption.
