r315034:
Document that the msun tests require WARNS=0

ATF tests have a default WARNS of 0, unlike other usermode programs. This
change is technically a noop, but it documents that the msun tests don't
work with any warnings enabled, at least not on all architectures.

r289172:

Refactor the test/ Makefiles after recent changes to bsd.test.mk (r289158) and
netbsd-tests.test.mk (r289151)

- Eliminate explicit OBJTOP/SRCTOP setting
- Convert all ad hoc NetBSD test integration over to netbsd-tests.test.mk
- Remove unnecessary TESTSDIR setting
- Use SRCTOP where possible for clarity

r290254:

Remove unused variable (SRCDIR)

Integrate contrib/netbsd-tests/lib/libcrypt/t_crypt.c in to the FreeBSD
test suite as lib/libcrypt/crypt_test

r291615 (by rodrigc):

Hack test so that it works on FreeBSD.

MFC r270144:

Add LIBCRYPT to DPADD, remove LDFLAGS from LDADD, and sort the Makefile variables

This fixes "make checkdpadd"

Phabric: D620

PR: 192729

MFC refactoring of the *.test.mk files.

- r263161 Make bsd.test.mk the only public mk fragment for the building of tests.
- r263172 Move FreeBSD Test Suite-specific code to a suite.test.mk file.
- r263204 Add some documentation for bsd.test.mk.
- r263217 Document support for TAP-compliant Perl test programs.

This is "make tinderbox" clean.

Set up the /usr/tests hierarchy.

This is a MFC of the following into stable/10:
- r257097 Set up the /usr/tests hierarchy.
- r257098 Add missing WITHOUTTESTS file.
- r257100 Add a tests(7) manual page.
- r257105 Disable WITHTESTS= for now.
- r257848 Fix buildworld when WITHTESTS is enabled.
- r257850 Subsume the functionality of MKATF into MKTESTS.
- r257851 Handle the removal of the test suite when WITHOUTTESTS=yes.
- r257852 Install category Kyuafiles from their category directories.
- r258232 Install BSD.tests.mtree when MKTESTS is yes.

Note that building with WITH_TESTS is still broken at this point (and
hence why WITHOUT_TESTS is the set as the default). Subsequent pullups
will fix the remaining issues.

Split and extend bsd.test.mk into {atf,plain,tap}.test.mk.

This is a MFC of:

- r256761 Clearly split the logic to build ATF and plain tests apart.
- r256762 Add the automatic generation of Atffile files.
- r256763 Add the automatic generation of Kyuafile files.
- r256764 Plug atf-run into the 'test' target.
- r256765 Plug kyua into the 'test' target.
- r257096 Move the TESTSBASE definition to bsd.own.mk.
- r257099 Add missing plain.test.mk.
- r258297 Remove registration of C++ test programs into PROGS.
- r258298 Fix the build of plain test programs.
- r258551 Install plain.test.mk.
- r259208 Add tap.test.mk.
