Merge the projects/release-pkg branch to head.

This allows packaging the base system with pkg(8), including
but not limited to providing the ability to provide upstream
binary update possibilities for non-tier-1 architectures.

This merge is a requirement of the 11.0-RELEASE, and as such,
thank you to everyone that has tested the project branch.

Documentation in build(7) etc. is still somewhat sparse, but
updates to those parts will follow.

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.

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.

Make telnet with SRA work.
