cf771f223b - Update FreeBSD's Heimdal distribution to 1.5.2. This is a bugfix
release, which fixes a DoS issue in libkrb5.

ae77177087 - Update FreeBSD Heimdal distribution to version 1.5.1. This also brings
several new kerberos related libraries and applications to FreeBSD:
  o kgetcred(1) allows one to manually get a ticket for a particular service.
  o kf(1) securily forwards ticket to another host through an authenticated
    and encrypted stream.
  o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1)
    and other user kerberos operations. klist and kswitch are just symlinks
    to kcc(1) now.
  o kswitch(1) allows you to easily switch between kerberos credentials if
    you're running KCM.
  o hxtool(1) is a certificate management tool to use with PKINIT.
  o string2key(1) maps a password into key.
  o kdigest(8) is a userland tool to access the KDC's digest interface.
  o kimpersonate(8) creates a "fake" ticket for a service.

  We also now install manpages for some lirbaries that were not installed
  before, libheimntlm and libhx509.

- The new HEIMDAL version no longer supports Kerberos 4.  All users are
  recommended to switch to Kerberos 5.

- Weak ciphers are now disabled by default.  To enable DES support (used
  by telnet(8)), use "allow_weak_crypto" option in krb5.conf.

- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
  disabled due to the function they use (krb5_get_err_text(3)) being
  deprecated.  I plan to work on this next.

- Heimdal's KDC now require sqlite to operate.  We use the bundled version
  and install it as libheimsqlite.  If some other FreeBSD components will
  require it in the future we can rename it to libbsdsqlite and use for these
  components as well.

- This is not a latest Heimdal version, the new one was released while I was
  working on the update.  I will update it to 1.5.2 soon, as it fixes some
  important bugs and security issues.

8998619212 Add support for dynamically adjusted buffers to allow the full use of
the bandwidth of long fat pipes (i.e. 100Mbps+ trans-oceanic or
trans-continental links).  Bandwidth-delay products up to 64MB are
supported.

Also add support (not compiled by default) for the None cypher.  The
None cypher can only be enabled on non-interactive sessions (those
without a pty where -T was not used) and must be enabled in both
the client and server configuration files and on the client command
line.  Additionally, the None cypher will only be activated after
authentication is complete.  To enable the None cypher you must add
-DNONE_CIPHER_ENABLED to CFLAGS via the make command line or in
/etc/make.conf.

This code is a style(9) compliant version of these features extracted
from the patches published at:

http://www.psc.edu/networking/projects/hpn-ssh/

Merging this patch has been a collaboration between me and Bjoern.

905571c031 Remove copyright strings printed at login time via login(1) or sshd(8).
It is not clear to what this copyright should apply, and this is in line
with what other operating systems do.

For ssh specifically, printing of the copyright string is not in the
upstream version so this reduces our FreeBSD-local diffs.

This also "reverts" some FreeBSD local changes so we should now
be back to using entirely stock OpenSSL.  The local changes were
simple $FreeBSD$ lines additions, which were required in the CVS
days, and the patch for FreeBSD-SA-09:15.ssl which has been
superseded with OpenSSL 0.9.8m's RFC5746 'TLS renegotiation
extension' support.

b40cdde64c Make OpenSSH work with utmpx.
- Partially revert r184122 (sshd.c). Our ut_host is now big enough to
  fit proper hostnames.

- Change config.h to match reality.

- defines.h requires UTMPX_FILE to be set by <utmpx.h> before it allows
  the utmpx code to work. This makes no sense to me. I've already
  mentioned this upstream.

- Add our own platform-specific handling of lastlog. The version I will
  send to the OpenSSH folks will use proper autoconf generated
  definitions instead of `#if 1'.
