Thus remove the VIMAGE conditional field from the domain(9) protosw
structure and replace it with VNET_SYSUNINITs.
This also allows us to change some order and to make the teardown functions
file local static.
Also convert divert(4) as it uses the same mechanism ip(4) and ip6(4) use
internally.
Slightly reshuffle the SI_SUB_* fields in kernel.h and add a new ones, e.g.,

Since META_MODE is being sold and used as a working incremental build, it won't
make much sense if filemon data is excluded. There is no way to recover

Adding .META to targets-to-build will ensure that they will rebuild if there
is no .meta file.
Adding it to all SUFFIXES and objects ensures that at least objects will
rebuild if there is no .meta file.
This will be reverted if bmake's behavior changes to rebuild on missing .meta

The C++ header files must be searched before /usr/include.
The original code in Makefile.inc1 did this before the change in r297271 to
use -isystem. The libc++ import in r300770 fixed the bug introduced in
r297271 by swapping XCFLAGS and XCXXFLAGS ordering in CROSSENV.
Moving the code from Makefile.inc1 to bsd.sys.mk in r300886 also made it
more difficult to control the order of the flags. CXXFLAGS is based on
CFLAGS, so any additions to it will come after CFLAGS. The CROSSENV
code from Makefile.inc1 was such that it was ensured the CXXFLAGS came
first by setting them directly in CXX. Using CXXFLAGS+=-I would work
here, but instead continue to use -isystem by adding it to CXX so it
comes before CFLAGS.

Fix the resource.fs.zfs.statechange message. It had a number of
problems:
It was only being emitted on a transition to the HEALTHY state.
That made it impossible for zfsd to take actions based on drives
getting sicker.
It compared the new state to vdev_prevstate, which is the state that
the vdev had the last time it was opened. That doesn't make sense,
because a vdev can change state multiple times without being
reopened.
vdev_set_state contains logic that will change the device's new
state based on various conditions. However, the statechange event
was being posted _before_ that logic took effect. Now it's being
posted after.

Passing MAKEOBJDIRPREFIX to the main prog build (rescue) would confuse
WITH_AUTO_OBJ and cause it to create a recursed object directory that
then broke the actual prog build. This is normally not a problem since
we do not call 'make -f prog.mk obj' before building anything in it.
Crunchgen(1) also assumes that if -o is not passed then if an object
directory does not already exist then it should build in the source
directories. The normal buildworld process will have already ran 'make
obj' in each of the component directories so this is not a problem.
With WITH_AUTO_OBJ though this is not the case. So we must tell
crunchgen(1) that MK_AUTO_OBJ=yes will create the directory and to not
require it be present before generating its Makefile.

The main prog has a dependency on the submake targets to ensure they are
built. From bsd.crunchgen.mk though we already have our own dependency
on 'make objs' so there is no need for another one. Crunchgen(1) is
doing the right thing here so it is not modified.
This also prevents the CC fix tainting the submake environment with
META_MODE and causing rebuilds. The CC passed is is only intended for

It turns out we need to leave this in place for a while so that people
running self-hosting armv6hf systems can do the builds necessary to update
to armv6 (which is now hardfloat by default).
This will still build the compiler for the target but will not build the
bootstrap cross-compiler in the cross-tools phase. Other toolchain
bootstrapping, such as elftoolchan and binutils, currently still occurs.
This will utilize the default CC (cc, /usr/bin/cc) as an external compiler.
This is planned to be on-by-default eventually.
This will utilize the __FreeBSD_cc_version compiler macro defined in the
source tree and compare it to CC's version. If they match then the
cross-compiler is skipped. If [X]CC is an external compiler (absolute
path) or WITHOUT_CROSS_COMPILER is already set, then this logic is skipped.
If the expected bootstrap compiler type no longer matches the found CC
compiler type (clang vs gcc), then the logic is skipped. As an extra
safety check the version number is also compared from the compiler to
the tree version.
Clang:
The macro FREEBSD_CC_VERSION is defined in:
lib/clang/include/clang/Basic/Version.inc
For clang -target will be used if TARGET_ARCH != MACHINE_ARCH. This
is from the current external toolchain logic. There is currently an
assumption that the host compiler can build the TARGET_ARCH. This
will usually be the case since we don't conditionalize target arch
support in clang, but it will break when introducing new
architectures. This problem is mitigated by incrementing the version
when adding new architectures.
GCC:
The macro FBSD_CC_VER is defined in:
gnu/usr.bin/cc/cc_tools/freebsd-native.h
For GCC there is no simple -target support when TARGET_ARCH !=
MACHINE_ARCH. In this case the opportunistic skip is not done. If we
add proper support for this case in external toolchain logic then it
will be fine to enable.
This relies on the macros being incremented whenever any change occurs
to these compilers that warrant rebuilding files. It also should never
repeat earlier values.

Add a pair of bus methods that can be used to "map" resources for direct
CPU access using bus_space(9). bus_map_resource() creates a mapping and
bus_unmap_resource() releases a previously created mapping. Mappings are
described by 'struct resource_map' object. Pointers to these objects can
be passed as the first argument to the bus_space wrapper API used for bus
resources.
Drivers that wish to map all of a resource using default settings
(for example, using uncacheable memory attributes) do not need to change.
However, drivers that wish to use non-default settings can now do so
without jumping through hoops.
First, an RF_UNMAPPED flag is added to request that a resource is not
implicitly mapped with the default settings when it is activated. This
permits other activation steps (such as enabling I/O or memory decoding
in a device's PCI command register) to be taken without creating a
mapping. Right now the AGP drivers don't set RF_ACTIVE to avoid using
up a large amount of KVA to map the AGP aperture on 32-bit platforms.
Once RF_UNMAPPED is supported on all platforms that support AGP this
can be changed to using RF_UNMAPPED with RF_ACTIVE instead.
Second, bus_map_resource accepts an optional structure that defines
additional settings for a given mapping.
For example, a driver can now request to map only a subset of a resource
instead of the entire range. The AGP driver could also use this to only
map the first page of the aperture (IIRC, it calls pmap_mapdev() directly
to map the first page currently). I will also eventually change the
PCI-PCI bridge driver to request mappings of the subset of the I/O window
resource on its parent side to create mappings for child devices rather
than passing child resources directly up to nexus to be mapped. This
also permits bridges that do address translation to request suitable
mappings from a resource on the "upper" side of the bus when mapping
resources on the "lower" side of the bus.
Another attribute that can be specified is an alternate memory attribute
for memory-mapped resources. This can be used to request a
Write-Combining mapping of a PCI BAR in an MI fashion. (Currently the
drivers that do this call pmap_change_attr() directly for x86 only.)
Note that this commit only adds the MI framework. Each platform needs
to add support for handling RF_UNMAPPED and thew new
bus_map/unmap_resource methods. Generally speaking, any drivers that
are calling rman_set_bustag() and rman_set_bushandle() need to be
updated.
