Add LIB_CXX so that C++ libraries will use CXX to link.

This fixes C++ libraries not implicitly linking in libc++. This is
generally not an issue because the final linking with the compiled binary
will involve CXX via PROG_CXX or other means. It is however
inconsistent with libraries implicitly linking in libc and problematic
for trying to build libraries with '-z defs' to ensure all direct
dependencies are linked in.

libatf-c++ is currently the only consumer of this new feature.

Homogenize libatf-* version numbers with upstream.

The libatf-* major version numbers in FreeBSD were one version ahead of
upstream because, when atf was first imported into FreeBSD, the upstream
numbers were not respected. This is just confusing and bound to cause
problems down the road.

Fix this by taking advantage of the fact that libatf-* are now private
and that atf is not yet built by default. However, and unfortunately, a
clean build is needed for tests to continue working once "make
delete-old-libs" has been run; hence the note in UPDATING.

Change libatf-c and libatf-c++ to be private libraries.

We should not be leaking these interfaces to the outside world given
that it's much easier for third-party components to use the devel/atf
package from ports.

As a side-effect, we can also drop the ATF pkgconfig and aclocal files
from the base system. Nothing in the base system needs these, and it
was quite ugly to have to get them installed only so that a few ports
could build. The offending ports have been fixed to depend on
devel/atf explicitly.

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

Add atf m4 files from the vendor branch.

These were originally deleted as "not important" but, actually we need them
in place if we want to be able to use autoconf on software that provides
atf-based tests. (That includes being able to rebuild autotest from scratch
on the Kyua cluster machines, as the automated setup does.)

MFV: Import atf-0.20.

Generate and install pkg-config files for atf.

These files are required to get packages in ports to build against atf and
also to get a couple of currently-failing tests to pass.

I'm following the approach already used by the libusb pkg-config files
installed by the system regarding the location and the install rules.

Remove -L<path> from LDADD, it doesn't belong there.
Add it to LDFLAGS instead.

Add ATF to the build. This is may be a bit rought around the egdes,
but committing it helps to get everyone on the same page and makes
sure we make progress.

Tinderbox breakages that are the result of this commit are entirely
the committer's fault -- in other words: buildworld testing on amd64
only.
