Remove $FreeBSD$: one-line sh pattern

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

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
^/projects/make-check-sandbox .

No functional change intended.

Explicitly add unmarked bin/ binaries to the runtime package.
Note: tcsh(1) has a MK_TCSH=no test, so this should be a separate
package, which requires pre-install/post-install scripts, to be
added later.

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

Some line ending issues had to be resolved with test outputs and scripts
via dos2unix and by deleting the eol-style property set in usr.bin/sort

Add the Clang specific -Wmissing-variable-declarations to WARNS=6.

This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.

Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.

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.

Get this area compiling with the highest WARNS= that it works with.
Obsolete WFORMAT= junk also removed where possible.

OK'ed by: obrien
Tested on: sparc64, alpha, i386

Disable -Werror when building -- the old version of gcc used on IA32 can't
deal with C99 formats.

Default to WARNS=2. Binary builds that cannot handle this must explicitly
set WARNS=0.

$Id$ -> $FreeBSD$

Simplified using new yacc rules and by not generating y.tab.h.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Backout yacc changes

Use default yacc rule.

``mv'' -> ``mv -f''
``rm'' -> ``rm -f''
so mv/rm may not ask for confirmation if you are not root

Remove trailing whitespace.
