MFC: r343011

Use ${SRCTOP}/contrib/com_err/com_err.h instead of the installed com_err.h.
This fixes build when com_err.h is not installed.

DIRDEPS_BUILD: Regenerate without local dependencies.

These are no longer needed after the recent 'beforebuild: depend' changes
and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports
skipping 'make depend'.

DIRDEPS_BUILD: Update dependencies.

META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.

This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Convert kerberos to LIBADD and reduce overlinking of the kerberos binaries and
libraries

* Remove headers from SRCS that are not generated
(and are in /usr/src/crypto/heimdal/).

* Avoid race conditions with 'make -j<N>'.

- 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.

- Add missing interdependencies to kerberos libraries. Some of the
kerberos libraries were not linked properly (missing dependencies),
which causes 3rd party applications linking to fail when --as-needed
ld flag is used. I also added the --no-undefined ld(1) flag to make
sure that there're no missing dependencies.

MFC after: 3 days

Fix conflicts after heimdal-1.1 import and add build infrastructure. Import
all non-style changes made by heimdal to our own libgssapi.

style.Makefile(5).

OK'ed by: nectar

Overhaul of kerberos5/ makefiles. Most significant changes are:

- Dropped support for standalone builds, this was only partially
supported anyway, and required so much magic in makefiles that
made life dangerous (e.g., by using the custom yacc rules).

- Got rid of .OBJDIR in makefiles -- makes building of individual
files possible again.

- Made the .x.c transformations -j safe.

- Reprogrammed LDADD to fix static build of some utilities that
was broken.

- Fixed LDFLAGS and DPADD in the WITH_OPENLDAP case -- positively
affects the contents of .depend files.

- Removed redundant .h's from SRCS, only kept those that are
generated.

- libkrb5/ INCS were bogusly installed again with libgssapi/.

- Made build-tools real tools with their own makefiles in
separate directories. This allows us to properly track
their dependencies, etc.

- Faster build, 21% less of makefile code!

Silence on: arch

The header files hdb_asn1.h, hdb_err.h, and kadm5_err.h are generated,
and must be installed from ${.OBJDIR}.

Pointy hat: nectar

Install additional headers for Kerberos (libkafs, libkadm5*, and
libhdb).

Big fixup of the makefiles. Sort out the dependancies so that "make"
without "make depend" works, "make -j N" works, and lists of source
files are made vertical to reduce future diffs.

Fix build, and make parallel build much more robust.
