librt: Hoist SHLIBDIR?= so it actually works

src.opts.mk includes bsd.own.mk, which sets SHLIBDIR, so having this
line after it does nothing. Hoist it like other libraries so it takes
effect.

librt: Chase 315ee00fa961, fixing boot

libzfs uses librt as a dependency. Following 315ee00fa961 systems with
a separate / and /usr will fail to load the libzfs.so library because
librt.so is not available due to the fact that /usr is not mounted yet.
Install librt in /lib making it available to libzfs.

pkgbase: Move librt to clibs

librt implement the POSIX realtime extension library.
Move it to clibs instead of utilities as a number of ports uses it
so avoid a dependancy on FreeBSD-utilities.

Don't add -Winline for WARNS=6

This warning is very rarely useful (inline is a hint and not mandatory).
This flag results in many warnings being printed when compiling C++
code that uses the standard library with GCC.

This flag was originally added in back in r94332 but the flag is a no-op
in Clang ("This diagnostic flag exists for GCC compatibility, and has no
effect in Clang"). Removing it should make the GCC build output slightly
more readable.

pkgbase: Create a FreeBSD-utilities package and make it the default one

The default package use to be FreeBSD-runtime but it should only contain
binaries and libs enough to boot to single user and repair the system, it
is also very handy to have a package that can be tranform to a small mfsroot.
So create a new package named FreeBSD-utilities and make it the default one.
Also move a few binaries and lib into this package when it make sense.

Add HAS_TESTS to all Makefiles that are currently using the
`SUBDIR.${MK_TESTS}+= tests` idiom.

This is a follow up to r321912.

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

Check in first src/tests snapshot from NetBSD anoncvs

Sources were obtained like so:

% export CVSROOT="anoncvs@anoncvs.NetBSD.org:/cvsroot"
% cvs -z9 co -D "09/30/2014 20:45" -P src/tests
% mv src/tests/* tests/dist/.

'*CVS*' has been added to svn:ignore to ease updating periodically from
upstream

Fix the 32-bit build stage on amd64 when WITH_CTF is enabled. It seems
ctfconvert will corrupt object files that are compiled with -g, if it is
not run with -g itself.

To fix it, remove -g from CFLAGS in lib/librt/Makefile. If you need to
compile this library with debug info, use DEBUG_FLAGS=-g instead, which
will work correctly, even when using WITH_CTF.

To support stack unwinding for cancellation points, add -fexceptions flag
for them, two functions _pthread_cancel_enter and _pthread_cancel_leave
are added to let thread enter and leave a cancellation point, it also
makes it possible that other functions can be cancellation points in
libraries without having to be rewritten in libthr.

Create the altix project branch. The altix project will add support

platform to test CPU affinity and NUMA-aware features in FreeBSD.

Build lib/ with WARNS=6 by default.

Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

link libpthread because the librt really needs it to fully function.

Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it.
Warning, after symbol versioning is enabled, going back is not easy
(use WITHOUT_SYMVER at your own risk).

Change the default thread library to libthr.

There most likely still needs to be a version bump for at least the
thread libraries. If necessary, this will happen later.

Don't enable symbol versioning for librt by default just yet.

No need to define NO_MAN here.
