The including makefile's directory is tried first for .include "...".

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.

Do not override BINDIR settings from subdirectory Makefiles.

Forced commit. This is to try and help folks that used the international
crypto repo and have slightly different files but with the same version.
cvsup in 'checkout mode' has no trouble with this, but cvs can get really
silly about it.

Add the OpenSSH userland-building Makefiles.
