Add baud rate support to telnet(1)

This implements part of RFC-2217

It's based off a patch originally written by Sujal Patel at Isilon, and
contributions from other Isilon employees.

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.

o Make telnet[d] -S (IP TOS) flag really work. We do not have
/etc/iptos implementation so only numeric values supported.

o telnetd.8: steal the -S flag description from telnet.1, bump
the date of the document.

o Remove -t flag from getopt(3), it was killed in rev. 1.15 three
years ago.

Fix up external variables named "debug" that have a horrible habit
of conflicting with other, similarly named functions in static
libraries. This is done mostly by renaming the var if it is shared
amongst modules, or making it static otherwise.

Use __FBSDID vs. rcsid[]. Also protect sccs[] and copyright[] from GCC 3.3.

Catch up with "base" telnet.

s/FALL THROUGH/FALLTHROUGH/ for lint(1).
s/Usage/usage/ for consistency.

Very large style makeover.

1) ANSIfy.
2) Clean up ifdefs so that
a) ones that never/always apply are appropriately either
fully removed, or just the #if junk is removed.
b) change #if defined(FOO) for appropiate values of FOO.
(currently AUTHENTICATION and ENCRYPTION)
3) WARNS=2 fixing
4) GC other unused stuff

This code can now be unifdef(1)ed to make non-crypto telnet.

Manually unifdef(1) CRAY, UNICOS, hpux and sun uselsess code.

Code merge and diff reduce with "base" telnet. This is the "later"
telnet, so it was treated as the reference code, except where later
commits were made to "base" telnet.

MF non-crypto: 1.13: document -u in usage.

Oops, forgot the 'u' in the getopt for the previous commit.

A feature to allow one to telnet to a unix domain socket. (MFC from
non-crypto version)

Also update the crypto telnet's man page to reflect other options
ported from the non-crypto version.

Back out last commit. This was already fixed. This should never have
happened, this is why we have commit mail expressly delivered to
committers.

Since the root-on-insecure-tty code was added to telnetd, a dependency
on char *line was added to libtelnet. Put a dummy one in to keep the
linker happy.

Clean up telnet's argument processing a bit. autologin and encryption is
now the default, so ignore the arguments that turn it on. Add a new -y
argument to turn off encryption in case someone wants to do that. Sync
these changes with the man page (including removing the now obsolete
statement about availability only in the US and Canada).

Bring the FreeBSD changes to the virgin sources.

Initial import of BSD telnet. This will be used to build the kerberised
telnet, and after userland diffs have been merged in, will be used to
build the non-kerberised sources as well. (See unifdef(1) for details)
