Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

Convert traditional ${MK_TESTS} conditional idiom for including test
directories to SUBDIR.${MK_TESTS} idiom

This is being done to pave the way for future work (and homogenity) in
^/projects/make-check-sandbox .

No functional change intended.

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

Add placeholder Kyuafiles for various top-level hierarchies.

This change adds tests/ directories in the source tree to create various
subdirectories in /usr/tests/ and to install placeholder Kyuafiles for
them.

the relevant hierarchies are: cddl, etc, games, gnu and secure.

The reason for this is to simplify the addition of new test programs for
utilities or libraries under any of these directories. Doing so on a
case by case basis is unnecessary and is quite an obscure process.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

Fix up the build for the STARTTLS version of sendmail (again). This method
mimics that of tcpdump in that for normal builds, sendmail will only be
built once. For 'make release', it is built once for the bin dist and
once for the crypto dist. This method also removes the need for two separate
Makefiles (which could become out of sync).

Activate the 'secure' (TLS) version of sendmail if !NO_SENDMAIL && !NO_OPENSSL

Don't build sshd if NO_OPENSSL defined.
