Clean up the OpenSSH build. It is now possible to build most components
as static binaries, if desired. The one exception is sshd, which runs
into trouble due to libpam.a's includion of pam_ssh.

Make OpenSSH use LDNS if available. This allows it to verify signed
SSHFP records.

Make libldns and libssh private.

Upgrade to OpenSSH 5.3p1.

Add a manual dependency on ssh_namespace.h.

Discussed with: ru

Introduce a namespace munging hack inspired by NetBSD to avoid polluting
the namespace of applications which inadvertantly link in libssh (usually
through pam_ssh)

Revert the commits that made libssh an INTERNALLIB; they caused too much
trouble, especially on amd64.

Requested by: ru

Make libssh an INTERNALLIB like it is in {Net,Open}BSD.

Update Makefiles for OpenSSH 3.7.1p2.

Explicitly add libz and libcrypto to LDADD for any ssh utilities missing
it. While not strictly required, it unbreaks the cross-build world that
is resulting from moving the libraries around.

I have a more permanent solution to this problem in the works, but I
asked des for permission to commit this to get the ball rolling. This
also makes the ssh build more along the lines of what the openssh-portable
and OpenBSD openssh Makefile glue does.

No guts, no glory. Switch to OpenSSH-portable.

My previous style commits weren't entirely right. Fix some bugs I
introduced, and a few more I hadn't yet fixed.

Adjust for OpenSSH 3.1.

Now that cross-tools ld(1) has been fixed to look for dynamic
dependencies in the correct place, record the fact that -lssh
depends on -lcrypto and -lz.

Removed false dependencies on -lz (except ssh(1) and sshd(8)).
Removed false dependencies on -lcrypto and -lutil for scp(1).

Add pam_ssh support to the static PAM library, libpam.a:

- Spam /usr/lib some more by making libssh a standard library.
- Tweak ${LIBPAM} and ${MINUSLPAM}.
- Garbage collect unused libssh_pic.a.
- Add fake -lz dependency to secure/ makefiles needed for
dynamic linkage with -lssh.

Follow the OpenSSH 2.9 upgrade with the infrastructure. Two new
programs are now included: sftp(1) and ssh-keyscan(1).

secure/ build fixes:

- TELNETOBJDIR is gone. `buildworld' already installs libtelnet.a
in ${WORLDTMP}/usr/lib, and we have LIBRARY_PATH pointing there.

- SSHDIR (formerly SSHSRC) is now shared between all SSH modules.
New LIBSSH is introduced for libssh.a (an internal static lib).
Previously, build without prior `obj' was broken; SSH modules
always looked for libssh.a in ${.OBJDIR}. Also, the dependancies
on the libssh.a were missing.

- libtelnet/ did not install the crypto version of telnet.h into
/usr/include/arpa.

- Removed BINOWN, BINMODE, BINDIR and SRCS with default values.

- MAN[1-9] -> MAN.

Don't pull in libRSAglue for the rsaref case. Since this is linked
dynamically by default, we use the dlopen() calls to load librsaref.so
on US code trees.

Add the OpenSSH userland-building Makefiles.
