Make sure everything linking to a privatelib and/or an internallib does it directly
from the OBJDIR rather than DESTDIR.
Add src.libnames.mk so bsd.libnames.mk is not polluted by libraries not existsing
in final installation
Introduce the LD* variable which is what ld(1) is expecting (via LDADD) to link to
internal/privatelib
Directly link to the .so in case of private library to avoid having to complexify
LDFLAGS.

iterating over the (possibly empty) list of members. Otherwise, we
get a false negative when the target group has no members listed in
/etc/group. This went mostly unnoticed because root is explicitly
listed as a member of wheel, so the bug is never triggered in the most
common use case, which is su(8).

lib/libpam/modules/pam_passwdqc/Makefile:
Bump WARNS to 2.
contrib/pam_modules/pam_passwdqc/pam_passwdqc.c:
Bump _XOPEN_SOURCE and _XOPEN_VERSION from 500 to 600
so that vsnprint() is declared.
Use the two new union types (pam_conv_item_t and
pam_text_item_t) to resolve strict aliasing violations
caused by casts to comply with the pam_get_item() API taking
a "const void **" for all item types. Warnings are
generated for casts that create "type puns" (pointers of
conflicting sized types that are set to access the same
memory location) since these pointers may be used in ways
that violate C's strict aliasing rules. Casts to a new
type must be performed through a union in order to be
compliant, and access must be performed through only one
of the union's data types during the lifetime of the union
instance. Handle strict-aliasing warnings through pointer
assignments, which drastically simplifies this change.
Correct a CLANG "printf-like function with more arguments
than format" error.

Before, we took the first argument to pam_exec(8). With the addition of
options in front of the command, this could be wrong.
Now, options are parsed before calling _pam_exec() and messages contain
the proper command name.
While here, fix a warning.

pam_exec(8) now accepts a new option "return_prog_exit_status". When
set, the program exit status is used as the pam_exec return code. It
allows the program to tell why the step failed (eg. user unknown).
However, if it exits with a code not allowed by the calling PAM service
module function (see $PAM_SM_FUNC below), a warning is logged and
PAM_SERVICE_ERR is returned.
The following changes are related to this new feature but they apply no
matter if the "return_prog_exit_status" option is set or not.
The environment passed to the program is extended:
o $PAM_SM_FUNC contains the name of the PAM service module function
(eg. pam_sm_authenticate).
o All valid PAM return codes' numerical values are available
through variables named after the return code name. For instance,
$PAM_SUCCESS, $PAM_USER_UNKNOWN or $PAM_PERM_DENIED.
pam_exec return code better reflects what went on:
o If the program exits with !0, the return code is now
PAM_PERM_DENIED, not PAM_SYSTEM_ERR.
o If the program fails because of a signal (WIFSIGNALED) or doesn't
terminate normally (!WIFEXITED), the return code is now
PAM_SERVICE_ERR, not PAM_SYSTEM_ERR.
o If a syscall in pam_exec fails, the return code remains
PAM_SYSTEM_ERR.
waitpid(2) is called in a loop. If it returns because of EINTR, do it
again. Before, it would return PAM_SYSTEM_ERR without waiting for the
child to exit.
Several log messages now include the PAM service module function name.
The man page is updated accordingly.

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.
the LDADD/DPADD to lose the -lpam, and causing openpam_dynamic() to fail
due to "openpam_get_options" being undefined.
This would cause obscure console log messages like:
openpam_dynamic(): No error: 0
openpam_load_module(): no pam_unix.so found
and other helpful messages which are no help in diagnosing the problem.
Fortunately this change was not mfc'ed to 9.x, it isn't broken there.
