28da5c6d7a Remove MK_AUTO_OBJ from env passed to PORTS_MODULES
This fixes a failure to resolve object file paths seen when buildkernel
(which sets MK_AUTO_OBJ=yes) and installkernel (which sets MK_AUTO_OBJ=no)
are run as separate steps.  r329232 partially fixed this scenario by removing
MAKEOBJDIR, but it seems the AUTO_OBJ setting also needs to be on the same
page for the build and install steps.

501608626d ports modules: Don't leak AUTO_OBJ changes into the port builds.

283f8a5c33 Remove system makefile path directives from env passed to PORTS_MODULES step
Previously, MAKESYSPATH as well as '-m' directives in MAKEFLAGS would cause
any port rebuilt during the PORTS_MODULES stage to consume system makefiles
from $(SRCROOT)/share/mk instead of those installed under /usr/share/mk.
For kernel modules that need to build against an updated src tree this
makes sense; less so for <bsd.port.mk> or  any userspace library or utility
the port may also happen to install.

Before 11.0, this probably didn't matter much in practice.  But the addition
of src.libnames.mk under $(SRCROOT)/share/mk in 11.0 breaks any consumer of
bsd.prog.mk and DPADD/LDADD during PORTS_MODULES.

Address the build breakage by removing MAKESYSPATH and any occurrence of
'-m' from MAKEFLAGS in the environment created for the port build.
Instead set SYSDIR so that any kmod built by the port will still consume
conf/kmod.mk from the updated src tree, assuming it uses <bsd.kmod.mk>

c30c436a58 FAST_DEPEND: Fix 'make all install' not properly rebuilding based on .depend.* files.
An optimization is in place to skip reading the .depend.* files with
'make install'.  This was too strong and broke 'make all install' and
'make foo.o foo install'.  Now only skip reading the dependency files
if all make targets ran are install targets.

The problem comes about because headers are only added in as a guessed
dependency if .depend.* files do not yet exist.  If they do exist, even
if being skipped from being read, then the header dependencies are not
applied.  This applies to all #included files, and not just headers.

ad8874fd21 Change the default build behavior so we don't compile extra TCP modules by
default. At least initially, the feature to support multiple TCP stacks is
aimed at supporting advanced use cases and TCP development, but it is not
necessarily aimed at a wide audience. Therefore, there is no need to build
and install the extra TCP stacks by default. Instead, the people who are
using or developing this functionality can add the extra option to build/
install the extra TCP stacks.

However, we do want to build the extra TCP stacks as part of test builds
(e.g. LINT or tinderbox) to ensure that developers who are testing their
changes will know that their changes do not break the additional TCP
stack modules.

After this change, a user will need to add WITH_EXTRA_TCP_STACKS=1 to
make.conf or the kernel config in order to build the extra TCP modules.

e32a2cbe39 FAST_DEPEND: Use .dinclude to enable full .depend logic in bmake.
The inclusion of .MAKE.DEPENDFILE (.depend) has special logic in make
to ignore stale/missing dependencies.  bmake 20160220 added a '.dinclude'
directive that uses the special logic for .depend when including the file.

This fixes a build error when a file is moved or deleted that exists in a
.depend.OBJ file.  This happened in r292782 when sha512c.c "moved" and an
incremental build of lib/libmd would fail with:
  make: don't know how to make /usr/src/lib/libcrypt/../libmd/sha512c.c. Stop

Now this will just be seen as a stale dependency and cause a rebuild:
  make: /usr/obj/usr/src/lib/libmd/.depend.sha512c.o, 13: ignoring stale .depend for /usr/src/lib/libcrypt/../libmd/sha512c.c
  --- sha512c.o ---
  ...
This rebuild will only be done once since the .depend.sha512c.o will
be updated on the build with the -MF flags.

This also removes -MP being passed for the .depend.OBJ generation (which
would create fake targets for system headers) since the logic is no
longer needed to protect from missing files.

b9cd412e7b FAST_DEPEND: Always run depend via beforebuild which removes many hacks.
This will generate dependencies rather than depending on the previous behavior
of depending on the guessed OBJS: *.h dependecies or a user running
'make depend'.

Experimentation showed that depending only on headers was not enough and
prone to .ORDER errors.  Downstream users may also have added
dependencies into beforedepend or afterdepend targets.  The safest way to
ensure dependencies are generated before build is to run 'make depend'
beforehand rather than just depending on DPSRCS+SRCS.

Note that the OBJS_DEPEND_GUESS mechanism (a.k.a .if !exists(.depend) then
foo.o: *.h) is still useful as it improves incremental builds with missing
.depend.* files and allows 'make foo.o' to usually work, while this
'beforebuild: depend' ensures that the build will always find all dependencies.
The 'make foo.o' case has no means of a 'beforebuild' hook.

This also removes several hacks in the DIRDEPS_BUILD:
- NO_INSTALL_INCLUDES is no longer needed as it mostly was to work around
  .ORDER problems with building the needed headers early.
- DIRDEPS_BUILD: It is no longer necesarry to track "local dependencies" in
  Makefile.depend.

  These were only in Makefile.depend for 'clean builds' since nothing would
  generate the files due to skipping 'make depend' and early dependency
  bugs that have been fixed, such as adding headers into SRCS for the
  OBJS_DEPEND_GUESS mechanism.  Normally if a .depend file does not exist then
  a dependency is added by bsd.lib.mk/bsd.prog.mk from OBJS: *.h.  However,
  meta.autodep.mk creates a .depend file from created meta files and inserts
  that into Makefile.depend.  It also only tracks *.[ch] files though which can
  miss some dependencies that are hooked into 'make depend'.  This .depend
  that is created then breaks incremental builds due to the !exists(.depend)
  checks for OBJS_DEPEND_GUESS.  The goal was to skip 'make depend' yet it only
  really works the first time.  After that files are not generated as expected,
  which r288966 tried to address but was using buildfiles: rather than
  beforebuild: and was reverted in r291725.  As noted previously,
  depending only on headers in beforebuild: would create .ORDER errors
  in some cases.

  meta.autodep.mk is still used to generate Makefile.depend though via:
    gendirdeps: Makefile.depend
    .END: gendirdeps

  This commit allows removing all of the "local dependencies" in
  Makefile.depend which cuts down on churn and removes some of the
  arch-dependent Makefile.depend files.

  The "local dependencies" were also problematic for bootstrapping.

70ca9ec4b9 Hook the meta/nofilemon build into using FAST_DEPEND.
FAST_DEPEND is intended to be the "skip 'make depend' and mkdep"
feature.  Since DIRDEPS_BUILD does this already with some of its own
hacks, and filemon doesn't need this, and nofilemon does, teach it how
to handle each of these cases.

In meta+filemon mode filemon will handle dependencies itself via the
meta mode logic in bmake.  We still want to set MK_FAST_DEPEND=yes to
enable some logic that indicates that 'make depend' is skipped in the
traditional sense.  The actual .depend.* files will be skipped.

When nofilemon is set though we still need to track and generate dependencies.

d7beff082b FAST_DEPEND: Rework how guessed dependencies are handled.
Rather than depend on .depend not existing, check the actual
.depend.OBJ file that will be used for that object.  If it doesn't
exist then use the guessed dependencies.

FAST_DEPEND may never have a .depend file.  Not having one means all of the
previous logic would over-depend all object files on all headers which is not
what we wanted.  It also means that if a .depend is generated before a build
is done for _EXTRADEPEND (such as for PROG or LIB) then all of these
dependencies would not be used since the .depend wasn't generated from mkdep
and the real .depend.* files are not generated until the build.
