Fix race between prebuilding libsbuf and libgeom

The latter needs the former, but with a multi-job build on a fast

MFC: r287805

Unconditionally build CTF tools in the bootstrap-tools phase of the build.

Stale CTF tools are a frequent source of DTrace issues, and they compile
quickly enough that the increase in build time is negligible.

Apart from what's described in the original commit message above, this
change also fixes building GENERIC kernels, i. e. kernel configurations
having "makeoptions WITH_CTF=1", when the host world has been built with
WITHOUT_CDDL.

MFC r324248:

hen building multiple kernels using KERNCONF, non-existent KERNCONF
files will produce an error and buildkernel will fail. Previously missing
KERNCONF files silently failed giving no indication as to why, only to
subsequently discover during installkernel that the desired kernel was
never built in the first place.

This is a rework of r302865.

This is the correct patch.

r313925:

MFC r285119,r292502,r295380:

r285119 (by jmmv):

Add support for TEST_METADATA

Allow Makefiles to define generic metadata settings that apply to all test
programs defined by a Makefile. The generic TEST_METADATA variable extends
the per-test program settings already supported via TEST_METADATA.<program>.

This feature will be useful to easily apply some settings to all programs
in a directory. In particular, Kyua 0.12 will support parallel execution
of test programs and a bunch of them will need to be tagged as is_exclusive
to indicate that they cannot be run in parallel with anything else due to
their side-effects. It will be reasonable to set this setting on whole
directories.

r292502:

Always expose LOCALBASE, not just when CROSS_TOOLCHAIN is defined

Instead of using which(1) to look for doxygen, look for it in <LOCALBASE>/bin .
$PATH gets mangled by make buildenv, etc so it's better to just be explicit
about the path if someone uses that for instance.

r295380:

Simplify running the FreeBSD test suite

Replace `make regress` (legacy test make target) and `make test` (incomplete
test make target added with the FreeBSD test suite) with make check as it's
consistent with other open source projects.

`make check` defaults to running tests from `.OBJDIR`, but can be overridden
with the `CHECKDIR` variable.

Add `make checkworld` target to simplify running the FreeBSD test suite from
`TESTSBASE` (i.e. the top-level tests directory), similar to buildworld.

Document `make check` and `make checkworld` in build(7).

Other minor changes:

- Rename intermediate file (`Kyuafile.auto`) to `Kyuafile` to simplify
`make check`.
- Remove terse warnings attached to `beforetest`/`aftertest`.
- Add kyua binary check to check target in suite.test.mk; error out if it's
not found

The MFC is [partly] contingent on other build related changes being MFCed.

Remove aicasm as a build dependency. It made sense when the ahc and ahd
drivers and their firmware were under active development, but those days

firmware from source, the glue still exists under the 'make firmware'
target in sys/modules/aic7xxx.

Integrate device-tree upstream files into the build process:
(1) Invoke cpp to bring in files via #include (although the old
/include/ stuff is supported still).
(2) bring in files from either vendor tree or freebsd-custom files
when building.
(3) move all dts* files from sys/boot/fdt/dts to
sys/boot/fdt/dts/${MACHINE} as appropriate.
(4) encode all the magic to do the build in sys/tools/fdt/make_dtb.sh
so that the different places in the tree use the exact same logic.
(5) switch back to gpl dtc by default. the bsdl one in the tree has
significant issues not easily addressed by those unfamiliar with
the code.

Only try to build the static dtb when we're building a static dtb.

Use proper include path for dtc as well as cpp.

Fix syntax errors (missing ; other minor glitches) in existing dts files.

Some xdev fixes:

- if TARGET_ARCH is not defined and XDEV_ARCH is defined then early define
TARGET_ARCH to the valud of XDEV_ARCH: This allow the xdev-build target
to be able to correctly chose the compiler it needs to build
- Allow overwriting XDTP to allow a user to not chose where the xdev env will
live in
- Fix build for gcc only xdev (like ia64) by providing the proper -B to the
toolchain and not relying on gcc being installed already in base
- Fix TOOLS_PREFIX so the generated toolchain has the right default sysroot when
installed intead of getting the DESTDIR one
- Fix supporting DESTDIR
- Also overwrite CXX (needed for cross building c++ libraries with clang) and
CPP (needed to cross build some libraries when gcc is the target default
compiler but gcc is not installed on the building host)
- Prevent XDTP from being a relative path:
XDTP is used as the default SYSROOT for clang and thus should be an absolute path.
- Respect default CC

Fix kern/187712: config(8) does not respect KERNCONFDIR.
The impact of this bug is that you cannot build a kernel if both of the
following are true:
1) The kernel config file is in a non-default location
2) The kernel config file uses the "include" statement from config(5).

usr.sbin/config/main.c
usr.sbin/config/config.8
usr.sbin/config/config.h
usr.sbin/config/lang.l
Added a "-I path" option to config(8). By analogy to cc(1), it adds
an extra path in which the "include" statement will search for
files.

Makefile.inc1
Pass "-I ${KERNCONFDIR}" to config(8).

Turn off warnings for building aicasm. Various versions of yacc exist,
which can result in different warnings-as-errors in this tool, but these
are all completely harmless.

This is a direct commit to stable/7, stable/8, stable/9 and stable/10,
since this kernel build tool has already been removed in head.

MFC 256640: Allow 'make xdev' to work when DESTDIR is set.

Hoist all the mergeinfo up to the root in preparation for enforcing merges
to the root only. All MFC's were rerecorded to the root.

Going forward, if an MFC includes mergeinfo, it will need to be made to
the root and committed from the root. Merges with --ignore-ancestry
or diff | patch can go anywhere.

The mergeinfo in HEAD is in a bad state from years of neglect and manual

This change is "make tinderbox" clean on ref10-amd64 with the default
settings of WITHOUT_TESTS. It is likely for the WITH_TESTS build to
still be broken because not all relevant changes have been merged yet.

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.

MFC 256640: Allow 'make xdev' to work when DESTDIR is set.

Hoist all the mergeinfo up to the root in preparation for enforcing merges
to the root only. All MFC's were rerecorded to the root.

Going forward, if an MFC includes mergeinfo, it will need to be made to
the root and committed from the root. Merges with --ignore-ancestry
or diff | patch can go anywhere.

The mergeinfo in HEAD is in a bad state from years of neglect and manual
tampering and this was branched into 10.x. This confuses the coalescing
code and prevents it from doing its job.

MFC r258086:
Strip the -pN patch level from the VERSION string which gets encoded into
CTF data. Otherwise FreeBSD Update builds think every kernel file has
changed every time there's a security advisory, since the FreeBSD Update
build code isn't smart enough to look inside CTF data to ignore those
changes.

MFC r257350:

In r257079, SRCDIR is pointed to ${.CURDIR} when not set. However,
Makefile.inc1 is being called in sub-make's where make(1) would,
by default, implicitly chdir(2) to ${.OBJDIR} before executing any
targets. This would make some targets, like delete-old, when trying
to derive various variables introduced by change r256921 using
``make -f Makefile.inc1'' that also rely on SRCDIR to fail.

This changeset adds an explicit cd ${.CURDIR} before these unwrapped
make calls, making them in line with the other ones that are already
being wrapped with the explicit chdir's.

MFC r256915

Stop conflating WITHOUT_CLANG with WITHOUT_CLANG_IS_CC. This allows
bootstrapping a copy of clang without building clang for the base system

which is useful for nanobsd and similar setups. It's still probably
wrong to conflate what is installed as /usr/bin/cc with the selection
of a bootstrap compiler under WITH*_CLANG_IS_CC, but that's for another
day.

MFC r256842:

Fix 'make delete-old-libs' and 'make check-libs' to delete .debug
files created by WITH_DEBUG_FILES. Also cleanup .symbols files from
the period between r244236 when .symbols were supported and r251512
when they were renamed to .debug.

Only propose to delete a .debug file if the corresponding library
itself was deleted already.
