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.

Fix conflicts after heimdal-1.1 import and add build infrastructure. Import
all non-style changes made by heimdal to our own libgssapi.

add hprop to the build and add LDAP mods to hprop.
add kadmind.8

Very big makeover in the way telnet, telnetd and libtelnet are built.

Previously, there were two copies of telnet; a non-crypto version
that lived in the usual places, and a crypto version that lived in
crypto/telnet/. The latter was built in a broken manner somewhat akin
to other "contribified" sources. This meant that there were 4 telnets
competing with each other at build time - KerberosIV, Kerberos5,
plain-old-secure and base. KerberosIV is no longer in the running, but
the other three took it in turns to jump all over each other during a
"make buildworld".

As the crypto issue has been clarified, and crypto _calls_ are not
a problem, crypto/telnet has been repo-copied to contrib/telnet,
and with this commit, all telnets are now "contribified". The contrib
path was chosen to not destroy history in the repository, and differs
from other contrib/ entries in that it may be worked on as "normal"
BSD code. There is no dangerous crypto in these sources, only a
very weak system less strong than enigma(1).

Kerberos5 telnet and Secure telnet are now selected by using the usual
macros in /etc/make.conf, and the build process is unsurprising and
less treacherous.

Post KerberosIV de-orbit: Clean up Kerberos5. We dont need KerberosIV
compatiblity mode anymore. Rename the k5foo utils to kfoo (after
repo-copy).

Revamp and diff-reduce the various secure telnets. Make sure that
Kerberos5 has _a_ telnet (which is not currently K5 enabled).
Incorporate BDE's static linking fixes.

Remove largescale evidence of crack-smoking.

Where a k4 applet has a k5 namesake, rename the k5 version
from k<app> to k5<app>. (Repo copy done).

Do some repairs to dependancies to support make world properly.

Userland build of Kerberos5 (AKA Heimdal). More to come.

This is not ready for primetime yet! Please hold off on the bug reports.
