MFC various moves of tools/regressions/ tests to the new infrastructure.

- r263220 Migrate tools/regression/sbin/ to the new tests layout.
- r263222 Add Makefile missed in r263220.
- r263226 Migrate tools/regression/{usr.bin/lastcomm,usr.sbin}/ to the new tests layout.
- r263227 Migrate most of tools/regression/usr.bin/ to the new tests layout.
- r263345 Expand tabs that sneaked in into spaces.
- r263346 Migrate tools/regression/usr.bin/make/ to the new tests layout.
- r263348 Add Makefiles missed in r263346.
- r263351 Migrate tools/regression/usr.bin/pkill/ to the new tests layout.
- r263388 Mark multi_test as requiring /usr/share/dict/words.
- r263814 Fix path to the run.pl script to let these tests run.
- r264742 Prevent building tests when bootstrapping make.

This is 'make tinderbox' clean.

+# $FreeBSD$
+
+dnl A library of routines for doing regression tests for userland utilities.
+
+dnl Start up.  We initialise the exit status to 0 (no failure) and change
+dnl into the directory specified by our first argument, which is the
+dnl directory to run the tests inside.
+define(`REGRESSION_START',
+TESTDIR=$1
+if [ -z "$TESTDIR" ]; then
+  TESTDIR=.
+fi
+cd $TESTDIR
+
+STATUS=0)
+
+dnl Check $? to see if we passed or failed.  The first parameter is the test
+dnl which passed or failed.  It may be nil.
+define(`REGRESSION_PASSFAIL',
+if [ $? -eq 0 ]; then
+  echo "ok - $1 # Test detected no regression. (in $TESTDIR)"
+else
+  STATUS=$?
+  echo "not ok - $1 # Test failed: regression detected.  See above. (in $TESTDIR)"
+fi)
+
+dnl An actual test.  The first parameter is the test name.  The second is the
+dnl command/commands to execute for the actual test.  Their exit status is
+dnl checked.  It is assumed that the test will output to stdout, and that the
+dnl output to be used to check for regression will be in regress.TESTNAME.out.
+define(`REGRESSION_TEST',
+$2 | diff -u ${SRCDIR:-.}/regress.$1.out -
+REGRESSION_PASSFAIL($1))
+
+dnl A freeform regression test.  Only exit status is checked.
+define(`REGRESSION_TEST_FREEFORM',
+$2
+REGRESSION_PASSFAIL($1))
+
+dnl A regression test like REGRESSION_TEST, except only regress.out is used
+dnl for checking output differences.  The first argument is the command, the
+dnl second argument (which may be empty) is the test name.
+define(`REGRESSION_TEST_ONE',
+$1 | diff -u ${SRCDIR:-.}/regress.out -
+REGRESSION_PASSFAIL($2))
+
+dnl A fatal error.  This will exit with the given status (first argument) and
+dnl print the message (second argument) prefixed with the string "FATAL :" to
+dnl the error stream.
+define(`REGRESSION_FATAL',
+echo "Bail out! $2 (in $TESTDIR)" > /dev/stderr
+exit $1)
+
+dnl Cleanup.  Exit with the status code of the last failure.  Should probably
+dnl be the number of failed tests, but hey presto, this is what it does.  This
+dnl could also clean up potential droppings, if some forms of regression tests
+dnl end up using mktemp(1) or such.
+define(`REGRESSION_END',
+exit $STATUS)
