Prior to this, setting VersionAddendum will be a no-op: one will
always have BASE_VERSION + " " + VERSION_HPN for VersionAddendum
set in the config and a bare BASE_VERSION + VERSION_HPN when there
is no VersionAddendum is set.
HPN patch requires both parties to have the "hpn" inside their
advertized versions, so we add VERSION_HPN to the VERSION_BASE
if HPN is enabled and omitting it if HPN is disabled.
VersionAddendum now uses the following logics:
* unset (default value): append " " and VERSION_ADDENDUM;
* VersionAddendum is set and isn't empty: append " "
and VersionAddendum;
* VersionAddendum is set and empty: don't append anything.

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.
- Revert unneeded whitespace changes.
- Revert modifications to loginrec.c, as the upstream version already
does the right thing.
- Fix indentation and whitespace of local changes.

I have worked hard to reduce diffs against the vendor branch. One

RSA - the reasons for doing so went away years ago. This may cause

From the OpenSSL advisory:
Andy Polyakov discovered a flaw in OpenSSL's DTLS
implementation which could lead to the compromise of clients
and servers with DTLS enabled.
DTLS is a datagram variant of TLS specified in RFC 4347 first
supported in OpenSSL version 0.9.8. Note that the
vulnerabilities do not affect SSL and TLS so only clients and
servers explicitly using DTLS are affected.
We believe this flaw will permit remote code execution.
