This reworks my last commit in r301285 to more closely match what was in
r241298 (but reverted in r294878).
This is addressing "missing .meta file" rebuilds but also ensuring that
files are always generated when needed in each case.
Note that this is not a complete rework of the problem areas identified
in r301285 as most are "good enough" right now as the new pattern
is too verbose. It's only worth making this current change where headers
may be generated in the INCS list; where missing .meta file rebuilds are
spotted.
--- Technical details follow ---
Several attempts to deal with this problem of multi-output targets, with and
without META MODE, were explained in r241298, r294878, and r301285.
The general problem is with multi-output targets such as:
foo.c foo.h:
touch foo.c foo.h
foo.c foo.h:
touch foo.c
touch foo.h
foo.c foo.h: foo.in
./generator ${.ALLSRC}
This pattern is problematic in jobs mode as both files end up being
built concurrently and leads to races. With META MODE it is worse
as both targets end up rebuilding if they lack a .meta file. So the
generator is force built twice even though it is only needed once.
There are also problems in that 'make foo.h' may be ran before 'make foo.c';
The order of make generating the targets is not guaranteed.
An older attempted workaround to this (discussed in r294878) was:
foo.h: foo.c
foo.c: foo.in
./generator ${.ALLSRC}
This appears fine except that if foo.h is missing and foo.c exists then
foo.h will never be regenerated. This pattern is close to the solution
in this commit though:
foo.h: foo.c .NOMETA
.if !exists(foo.h)
foo.c: .PHONY .META
.endif
foo.c: foo.in
./generator ${.ALLSRC}
There's 2 differences here:
1. foo.h will never expect to have a .meta file since the foo.c target
will generate both and own the .meta file.
2. If foo.h does not exist then it needs to force foo.c to be rebuilt
with .PHONY. That normally disables META MODE though so .META is
given to tell bmake we do really expect a .meta file.
This pattern cannot work with implicit suffix rules since the .c and .h files
may be generated at different times (buildincludes vs depend/all).

This is still targeting bin/sh cyclic dependency issues. Only apply
guessed dependencies that are explicitly set for an object (which
gnu/lib/cc/cc_tools needs) and if no custom target exists with its
own dependencies.
This was manifesting as a missing yacc.h in usr.bin/mkesdb_static when
built without -j (or -B). No actual yacc.h dependency ordering was
defined but with -j it got lucky and built fine.

Default to tracking .depend.* for OBJS rather than SRCS.
This helps cover some special case builds like gnu/lib/csu which
do more of a PROGS-like thing with bsd.prog.mk.
It is possible this causes out-of-tree Makefiles to have problems if they use
this pattern:
foo.o: foo.c
${CC} -o ${.TARGET} ${.ALLSRC}
This may cause multiple source files to be compiled due to finding the
'foo.o: foo.c' dependency both in the Makefile at the .depend file. Or
it may try compiling headers. This can be worked around by either of these:
foo.o: foo.c
${CC} -o ${.TARGET} ${.ALLSRC:N*.h:[1]}
Or
foo.o: foo.c
${CC} -o ${.TARGET} ${.CURDIR}/foo.c
In the latter case the ${.CURDIR} may need to be a different path. The
first case covers automatically using .PATH.

This is in the case of not having any .depend.foo.o yet. Don't force add *.h
as a dependency for those. They are built in beforebuild already when in
SRCS/DPSRCS.
This change allows custom rules, like in bin/sh/Makefile for mksyntax, to not
have cyclic dependency problems when connected to the .depend.* handling.
This is purposely not copied to sys/conf/kern.post.mk as it handles
generating headers slightly differently.

r345708 worked for the base system, but unfortunately, caused a lot of
disruption for third-party packages that relied on C++, since bsd.sys.mk is
used by applications outside the base system. The defaults picked didn't match
the compiler's defaults and broke some builds that didn't specify a standard,
as well as some that overrode the value by setting `-std=gnu++14` (for
example) manually.
This change takes a more relaxed approach to appending `-std=${CXXSTD}` to
CXXFLAGS, by only doing so when the value is specified, as opposed to
overriding the standard set by an end-user. This avoids the need for having
to bake NOP default into bsd.sys.mk for supported compiler-toolchain
versions.
In order to make this change possible, add CXXSTD to Makefile snippets which
relied on the default value (c++11) added in r345708.

The current approach of injecting manifest into mac_veriexec is to
verify the integrity of it in userspace (veriexec (8)) and pass its
entries into kernel using a char device (/dev/veriexec).
This requires verifying root partition integrity in loader,
for example by using memory disk and checking its hash.
Otherwise if rootfs is compromised an attacker could inject their own data.
This patch introduces an option to parse manifest in kernel based on envs.
The loader sets manifest path and digest.
EVENTHANDLER is used to launch the module right after the rootfs is mounted.
It has to be done this way, since one might want to verify integrity of the init file.
This means that manifest is required to be present on the root partition.
Note that the envs have to be set right before boot to make sure that no one can spoof them.

The behavior prior to this change would not override default values if set in
`bsd.own.mk`, or (in the more general case) globally before `bsd.progs.mk` was
included. This affected `bsd.test.mk` as well, since it consumes
`bsd.progs.mk`.
Some examples of this failing behavior are as follows:
* `BINMODE` defaults to 0555 per `bsd.own.mk`. If someone wanted to set the
`BINMODE` to `NOBINMODE` (0444) for `prog`, for example, like
`BINMODE.prog= ${NOBINMODE}`, `bsd.progs.mk` would not honor the per-PROG
setting.
* An application, `prog`, does not build at `WARNS?= 6`. Before this change,
setting to a lower `WARNS` value, e.g., `WARNS.prog= 3`, would have been
impossible, requiring that `prog` be built from another directory,
the global `WARNS` be lowered, or a per-PROG value needing to be set
across the board. None of the above workarounds is desirable.
This change unbreaks variables defined in `PROG_OVERRIDE_VARS` which have
defaults set before `bsd.progs.mk` is included, by setting them to their
defined values if set on a per-PROG basis.

The current logic for CSTD/CXXSTD requires homogenity as far as the
supported C/C++ standards, which is a sensible default. However, when
dealing with differing versions of C++, some code may compile with C++11, but
not C++17 (for instance). So in order to avoid having people convert over their
code to the new standard, give the users the ability to specify the standard on
a per-program basis.
This will allow a user to override the supporting standard for a set of
programs, mixing C++11 with C++14 (for instance).

This makes it easier for googletest users to leverage googletest, instead of
forcing them to plug GTEST_CXXFLAGS into CXXFLAGS manually (resulting in

src.libnames.mk should be automatically adding this directory to
CFLAGS/CXXFLAGS when private libraries are referenced. Not doing so can result
in mismatches between base-provided private library's and ports-provided

This initial integration takes googlemock/googletest release 1.8.1, integrates
the library, tests, and sample unit tests into the build.
googlemock/googletest's inclusion is optionally available via `MK_GOOGLETEST`.
`MK_GOOGLETEST` is dependent on `MK_TESTS` and is enabled by default when
built with a C++11 capable toolchain.
Google tests can be specified via the `GTESTS` variable, which, in comparison
with the other test drivers, is more simplified/streamlined, as Googletest only
supports C++ tests; not raw C or shell tests (C tests can be written in C++
using the standard embedding methods).
No dependent libraries are assumed for the tests. One must specify `gmock`,
`gmock_main`, `gtest`, or `gtest_main`, via `LIBADD` for the program.
More information about googlemock and googletest can be found on the
Googletest [project page](https://github.com/google/googletest), and the

and
[GoogleTest](https://github.com/google/googletest/tree/v1.8.x/googletest/docs)
