MFC r259286,259424,259425:
Apply patch from upstream Heimdal for encoding fix

RFC 4402 specifies the implementation of the gss_pseudo_random()
function for the krb5 mechanism (and the C bindings therein).
The implementation uses a PRF+ function that concatenates the output
of individual krb5 pseudo-random operations produced with a counter
and seed. The original implementation of this function in Heimdal
incorrectly encoded the counter as a little-endian integer, but the
RFC specifies the counter encoding as big-endian. The implementation
initializes the counter to zero, so the first block of output (16 octets,
for the modern AES enctypes 17 and 18) is unchanged. (RFC 4402 specifies
that the counter should begin at 1, but both existing implementations
begin with zero and it looks like the standard will be re-issued, with
test vectors, to begin at zero.)

This is upstream's commit f85652af868e64811f2b32b815d4198e7f9017f6,
from 13 October, 2013:
% Fix krb5's gss_pseudo_random() (n is big-endian)
%
% The first enctype RFC3961 prf output length's bytes are correct because
% the little- and big-endian representations of unsigned zero are the
% same. The second block of output was wrong because the counter was not
% being encoded as big-endian.
%
% This change could break applications. But those applications would not
% have been interoperating with other implementations anyways (in
% particular: MIT's).

Bump __FreeBSD_version accordingly and add a note in UPDATING.

Fix gssapi/gssapi_krb5.h after Heimdal 1.5.1 import.

Reviewed by: dfr

Have the ipropd-master listen on an IPv6 socket in addition to an IPv4
socket to allow propagation of changes to a Heimdal Kerberos database
from the KDC master to the slave(s) work on IPv6 as well.

Update the stats logging to also handle IPv6 addresses.

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

- 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.

Fix clang warning (why is there nowhere yyparse() is declared?).

Fix the amd64 (and presumably ia64) lib32 build by ensuring that the
heimdal GSS-API mechanism uses its own version of gssapi.h, including all
the implementation-dependant pollution contained therein.

This moves the file off the vendor branch, sadly.
