This fixes the following errors:
make: don't know how to make bsd.README. Stop
make: don't know how to make auto.obj.mk. Stop
This is easily seen in sys/dev/*.
The new behavior is now the expected output:
make: no target to make.
This would happen as MAKESYSPATH (.../share/mk) is auto added to the -I list.
Any directory where make is ran in the src tree that has no local Makefile
would then try executing the target in share/mk/Makefile, which by default
was to build the first entry in FILES. Of course, because bsd.README and
auto.obj.mk are not in the current directory the error is shown.
This check only works for bmake, but I will still MFC it with an extra
'!defined(.PARSEDIR) ||' guard for stable/10.

This avoids needing a large boot partition / file system in order to
accommodate multiple kernels, and provides consistency with userland
debug. This also simplifies the process of moving kernel debug files
to a separate package and installing them on demand.
In addition, change kernel debug file extension to .debug, to match
userland debug files.
When using the supported kernel installation method the
/usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
as is done with /boot/kernel.
Developers wishing to maintain the historical behavior of installing
debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).

This mostly fixes an interaction with bsd.test.mk with PROGS and SCRIPTS.
This was most notable with 'make clean' and 'make install', which r281055
and r272055 attempted to address but were inadequate.
It also addresses similar issues in bsd.progs.mk when not using bsd.test.mk.
This also fixes cases of NOT running commands in the parent when using
bsd.progs.mk:
- 'make clean' was not run for the main process for Makefiles which had both
FILES and SUBDIR but no PROGS or SCRIPTS. This usually was just a
leftover Kyuafile.auto. One such example is usr.bin/bmake/tests/sysmk/t1/2.
- 'make obj' was not running in the current directory with bsd.test.mk due
to early inclusion of bsd.subdir.mk. This was not really a problem due to
the SUBDIRS using 'mkdir -p' for their objdirs.
There were subtle bugs causing this wrong behavior:
1. bsd.progs.mk needs to set SCRIPTS to empty when recursing to avoid
the sub-makes from installing, cleaning or building the SCRIPTS;
only the parent make should be doing this. r281055 effectively did
the same but wasn't enough.
2. CLEANFILES may contain (especially from *.test.mk) files which only
the parent should clean, such as from FILES and SCRIPTS. To resolve
sub-makes also cleaning these, reset CLEANFILES and CLEANDIRS in the
children before including bsd.prog.mk. A tempting alternative would be
to only handle CLEANFILES in the parent but then the child bsd.prog.mk
CLEANFILES of per-PROGS wouldn't be setup.
3. bsd.subdir.mk was included too soon in bsd.test.mk. It needs to be
included after bsd.prog.mk as the SCRIPTS logic is short-circuitted if
'install:' is already defined (which bsd.subdir.mk does). There is
actually no need to include bsd.subdir.mk from bsd.test.mk as bsd.prog.mk
and bsd.obj.mk will do so in the proper order. The description in r257095
covers this for FILES and was fixed differently, though changing the
handling of target(install) in bsd.prog.mk may make sense after more
research.
4. bsd.progs.mk had extra logic to handle recursing SCRIPTS if PROGS was
empty, which isn't its business to be doing. SCRIPTS is handled fine
by bsd.prog.mk. This mostly reverts and reworks the fix in r259209 and
partially reverts r272055.
5. bsd.progs.mk has no need to depend 'all:' on SCRIPTS and FILES. These
are handled by bsd.prog.mk/bsd.files.mk fine. This also partially reverts
r272055.
6. bsd.progs.mk was not drop-in safe for bsd.prog.mk. Move the PROGS
check from r273186 to allow it to be used safely.
Specific tested cases:
SCRIPTS:no PROGS:no FILES:yes SUBDIR:yes
usr.bin/bmake/tests/sysmk/t1/2
SCRIPTS:yes PROGS:no FILES:yes SUBDIR:no
usr.bin/bmake/tests/sysmk/t1/2/1
SCRIPTS:yes PROGS:yes FILES:yes SUBDIR:yes
lib/libthr/tests
SCRIPTS:yes PROGS:no FILES:yes SUBDIR:no
usr.bin/yacc/tests
libexec/atf/atf-sh/tests
A full buildworld/installworld/clean comparison with mtree was also done.
The only relevant difference was the new fixed behavior of removing
Kyuafile.auto from the objdir in 'clean'.
Converting SCRIPTS to be a special case FILES group will make this less
fragile and is being explored.
One known remaining issue is 'cleandepend' removing the tags files for
every recursive call.
Note that the 'make clean' command runs for the CURDIR last, which can make
it appear to run multiple times when cleaning in tests/, but each command is
for a SUBDIR returning up the chain. This is purely bsd.subdir.mk behavior.

In the first build the TOOLSDIR does not exit yet which causes CC to default
to the sys.mk version. Once a TOOLSDIR is created during the build though,
this logic was changing CC to ${TOOLSDIR}/usr/bin/cc even though that file
did not exist. Thus CC went from 'cc' to '/usr/bin/cc' which forced a
rebuild of everything while using the same compiler. Check that TOOLSDIR is
not empty to avoid this. If there is actually a TOOLSDIR cc then it will be
used and properly rebuild.

Filemon(4) will record paths as they are seen, not as fully resolved. make(1)
will take the .MAKE.META.IGNORE_PATHS values and resolve them. This creates
a discrepancy if CCACHE_DIR is a symlink. Fix this by ensuring it is
resolved for its actual usage.

This limits CLEANFILES removal to just bsd.obj.mk now and removes the need
for NOPATH_FILES.
This reverts r96529 which was done due to the command line being too long
for libc. Since then all architectures now use 256k for ARG_MAX (r170102).
Regardless of that, the libc CLEANFILES is only 72k now. Others
may be larger but not likely to hit the limit. If needed, we can improve
the bsd.obj.mk clean: target to split up the list via bmake features.
This also removes some workarounds that are no longer needed.
- a.out removal
- OBJS.tmp, which has not been needed since r117080.
- *.so, which has not been needed since a .so->.So rename in r42450.
This also fixes STATICOBJS and SHLIB_LINK not being in the .NOPATH list.

r284708 addressed this slightly but seems to have put the make(showconfig)
guard in the wrong place. Rather than guard setting the default obj directory,
guard inclusion of auto.obj.mk. This avoids creating SRCTOP/obj and
SRCTOP/release/obj when running makeman.

This avoids easily colliding multiple src trees with the same objects. Having
multiple checkouts in dir/ dir2/ dir3/ would all use obj/ without any unique
identifier inside of obj/. This pattern is more likely to be used due
to the non-META_MODE behavior working with it fine.
In environments where ../obj/ is wanted as the obj directory the value of
OBJROOT can be set to ${SRCTOP:H}/obj/ instead via src-env.conf (set by
SRC_ENV_CONF) or environment. For environment it must be single quoted or
escaped. This will be more likely for vendors who are building images or using
NFS for builds. In those cases MAKEOBJDIRPREFIX may already be utilized and
is supported.

The preferred way to modify the object directory root is to use OBJROOT.
However, setting OBJROOT to ${MAKEOBJDIRPREFIX}/${SRCTOP}/ effectively behaves
as expected.
The problem with this before was that setting OBJROOT to contain SRCTOP
resulted in a recursive replacement (/usr/obj/usr/obj/usr/src/). Anchoring to
the start of the path for replacing SRCCTOP in CURDIR resolves this by
avoiding replacing SRCTOP when CURDIR is within the OBJDIR.

This would lead to the 2nd build (after the first with a missing OBJROOT) to
always rebuild everything as the 'command' would have changed due to the path
changing from having // to only /.

MAKEOBJDIR is based on OBJTOP so cannot be expanded until OBJTOP is set.

branch.
This function is used to drain a callout via a callback instead of
blocking the caller until the drain is complete. Refer to the
callout_drain_async() manual page for a detailed description.
Limitation: If a lock is used with the callout, the callout can only
be drained asynchronously one time unless the callout_init_mtx()
function is called again. This limitation is not present in
projects/hps_head and will require more invasive changes to the
timeout code, which was not in the scope of this patch.
