Export gssrpc_bindresvport_sa

It was added in commit 0d04b60d159ab83b943e43802b1449a3b074bc83, but
was not added to the library export symbol list, and thus was unusable
on systems that enforced library export lists.

Map .hin files to the C language for doxygen

In Debian unstable, the current version of doxygen is unhappy with
our generated Doxyfile, and does not handle krb5.hin in the expected
fashion (as a C header).  Work around this issue by explicitly
specifying that files with the .hin extension are to be treated
as C language files.

Fix KCM ccache per-type cursor

The KCM per-type cursor was too simplistic and did not obey the
conventions of the other ccache types.  Fix it to return a singleton
cursor when the default cache is a subsidiary and to return the
primary cache first.

For internal convenience, make_cache now accepts a context parameter
and creates a kcmio if necessary.

Fix unlikely memory leak in KCM client

Commit 956cbd24e645609c94fbc836840ce0f87ba3ce79 created a memory leak

Update NOTICE with new changes for 1.13

The KCM RPC definitions are copyright KTH/Apple, since it is present
for interoperability with OS X.

Add MS-KKDCP client copyright; alas, it does not match the existing
Red Hat copyrights, since the new code is a 2-clause BSD license, and
there was only a 3-clause Red Hat copyright block present already.

The actual Sphinx output for NOTICE would adjust the wrapping and
indentation of some existing content, but those changes were removed
by hand, so this commit only reflects new added content.

Re-encrypt preserved key data in new master key

When we are preserving old key data in kdb_cpw.c, ensure that it is
encrypted with the same master key as the new key data.  This ensures
that the KRB5_TL_MKVNO tl-data on the principal entry applies to all
of the key data, not just some of it.

Simplify kdb_cpw.c

In add_key_rnd, stop looking up the krbtgt DB entry; we have not used
it since 1.1.

Use copy_key_data in add_key_rnd and add_key_pwd.

krb5_dbe_crk, krb5_dbe_ark, krb5_dbe_def_cpw, and krb5_dbe_apw all
contained similar logic.  Consolidate all of them into a static helper
function which does the work of all four.  The ark/apw variants had
slightly different behavior then crk/cpw with keepold=true, so
introduce a three-value enum to express all three behaviors.
Fix uninitialized variable bug in kdb_cpw.c

Now that add_key_rnd isn't looking up the TGT principal entry, it
could use retval before initializing it if the loop runs for zero
iterations.  Get rid of the add_key_rnd label (as it no longer does
anything) and just return 0 after the loop ends.
In ksu, handle typeless default_ccache_name values

When a configured or compiled-in default ccache name doesn't contain a
cache type and ':' as a prefix, add one to the writeable value that we
construct when we go to look it up.  This lets the rest of the
application always assume that it'll be there.

Try to scan_ccache() after leash picks a cache

We need to call scan_ccache() in order to notice that there
are credentials and read their expire time.

Let libgssapi see TGTs in the MSLSA cache

When the current user is a local administrator of a windows machine
where User Account Control (UAC) is enabled, the Windows LSA will
return a block of zeros as the session key for any TGT entry in the
MSLSA: cache.  The lcc_retrieve() implementation checks for such
"null" session keys and prevents them from escaping to callers (as
attempts to use them would encounger strange errors).  However,
when the TGT is the only entry in the cache, this filtering prevents
scan_ccache() from detecting that the cache contains non-expired
credentials (and that there is a TGT present).

Since scan_ccache() is only looking at metadata in the cache entries,
and does not need to actually use any tickets or session keys, set
the KRB5_TC_NOTICKET flag on the ccache before scanning it.  This
will allow the MSLSA implementation to return a cred for the TGT
entry and cause the GSSAPI credential selection algorithm to function
properly.

Remove old Windows support from cc_mslsa.c

It is safe to remove is_windows_2000(), is_windows_xp(), and
is_windows_vista(), since the former two only check for very old
versions of windows which are no longer supported, and
is_windows_vista() was unused.  Note that the check being implemented
was whether the running OS was the named version or higher, not an
exact match.  The current Microsoft documentation recommends against
the sort of OS version checks that were employed here, in favor of
explicit feature tests.

Remove is_broken_wow64() as the problem it works around (Microsoft
Article ID 960077) is believed to have been fixed in subsequent
updates to Windows Server 2003 and XP.

Remove does_retrieve_ticket_cache_ticket() since support for the
KERB_RETRIEVE_TICKET_CACHE_TICKET flag in the
KERB_RETRIEVE_TKT_REQUEST structure was added in service packs for
Windows Server 2003 and XP.  Also remove buildtime fallbacks that
are no longer needed.

Remove the conditionals TRUST_ATTRIBUTE_TRUST_USES_AES_KEYS,
HAVE_CACHE_INFO_EX2, and KERB_SUBMIT_TICKET as all current SDK
versions have the relevant functionality.

In all cases, de-indent chunks that are no longer conditional.
Where indentation levels changed, update the style of the reindented
code to current practices.

Remove unused code from cc_mslsa.c

Remove PreserveInitialTicketIdentity() and IsKerberosLogon(), as well
as the preprocessor conditionals ENABLE_PURGING and PURGE_ALL, which
have not been used in a very long time, if ever.

There was one potential callsite of IsKerberosLogon(), in
lcc_resolve(), which was disabled.  It is perfectly reasonable to want
to use the MSLSA cache on a non-domain-joined workstation, as it is
now a read-write cache type, so we need not concern ourselves whether
the logon was performed or may have been performed using kerberos.
