Several third-parties use at least some of these ioctls. While it would be
better for regression testing if they were used in base (or at least in the
test suite), it's currently not worth the trouble to push through removal.

ACFLAGS is only used in addition to CFLAGS, so setting the options in
both was redundant. However, ACFLAGS is added to the command line
after CFLAGS, so the settings from ACFLAGS were applied for assembly
files in kernel modules after the kernel-specific march/abi in CFLAGS.
As a result, the hard-float ACFLAGS in bsd.cpu.mk was overriding the
soft-float CFLAGS.gcc in sys/conf/kern.mk. In particular,
dtrace_asm.o was compiled as hard-float and the linker refused to link
dtrace.ko since its object files contained a mix of hard and soft
float.

For developers gensnmptree can now generate functions for enums to convert
between enums and strings and to check the validity of a value.
The sources in FreeBSD are now in sync with the upstream which allows to
bring in IPv6 modifications.
API documented in previous version of uhid(4) man page has been obsolete
since May 2009 when old USB stack was replaced with USB2 implentation.
Current API has the same set of ioctl calls but uses usb_gen_descriptor
structure to pass data to/from kernel.

Update carp to set DSCP value CS7(Network Traffic) in the flowlabel field of
packets by default. Currently carp only sets TOS_LOWDELAY in IPv4 which was
deprecated in 1998. This also implements sysctl that can revert carp back to
it's old behavior if desired.
This will allow implementation of QOS on modern network devices to make sure
carp packets aren't dropped during interface contention.

Several ioctls are unused in pf, in the sense that no base utility
references them. Additionally, a cursory review of pf-based ports
indicates they're not used elsewhere either. Some of them have been
unused since the original import. As far as I can tell, they're also
unused in OpenBSD. Finally, removing this code removes the need for
future pf work to take them into account.

Need to handle LLD_BOOTSTRAP separately (for archs like i386).
This would be much better off with an off-by-default option like
SHARED_TOOLCHAIN that universe force-enabled. Then a normal buildworld
would store the toolchain there if enabled and otherwise in WORLDTMP
with only the 1 arch selected.

LLVM_TARGET_* will auto be set based on LLVM_TARGET_ALL and MK_CLANG.
If LLVM_TARGET_ALL is disabled, during a cross-build, then SYSTEM_COMPILER
and SYSTEM_LINKER are auto disabled.
This option should be used by users rather than the per-arch LLVM_TARGET
options as it is simpler to maintain for them should the supported
target list change.

Allow attaching of multiple geli providers at once if they use same
passphrase and keyfiles.
This is helpful when the providers being attached are not used for boot,
and therefore the existing code to first try the cached password when
tasting the providers during boot does not apply.
Multiple providers with the same passphrase and keyfiles can be attached
at the same time during system start-up by adding the following to
rc.conf:
geli_groups="storage backup"
geli_storage_flags="-k /etc/geli/storage.keys"
geli_storage_devices="ada0 ada1"
geli_backup_flags="-j /etc/geli/backup.passfile -k /etc/geli/backup.keys"

Add documentation and symlinks for OF_getprop_alloc_multi
and OF_getencprop_alloc_multi functions.
Also while here fix copy-pasted .Dt value and add one more
failure condition for OF_getencprop_alloc.
r332341 introduced OF_getencprop_alloc_multi that should be used
instead of OF_getencprop_alloc to get multi-cell properties.
Fix example to reflect this change.
Normally pf rules are expected to do one of two things: pass the traffic or
block it. Blocking can be silent - "drop", or loud - "return", "return-rst",
"return-icmp". Yet there is a 3rd category of traffic passing through pf:
Packets matching a "pass" rule but when applying the rule fails. This happens
when redirection table is empty or when src node or state creation fails. Such
rules always fail silently without notifying the sender.
Allow users to configure this behaviour too, so that pf returns an error packet
in these cases.

This makes it possible, through src.conf(5) settings, to select which
LLVM targets you want to build during buildworld. The current list is:
* (WITH|WITHOUT)_LLVM_TARGET_AARCH64
* (WITH|WITHOUT)_LLVM_TARGET_ARM
* (WITH|WITHOUT)_LLVM_TARGET_MIPS
* (WITH|WITHOUT)_LLVM_TARGET_POWERPC
* (WITH|WITHOUT)_LLVM_TARGET_SPARC
* (WITH|WITHOUT)_LLVM_TARGET_X86
To not influence anything right now, all of these are on by default, in
situations where clang is enabled.
Selectively turning a few targets off manually should work. Turning on
only one target should work too, even if that target does not correspond
to the build architecture. (In that case, LLVM_NATIVE_ARCH will not be
defined, and you can only use the resulting clang executable for
cross-compiling.)
I performed a few measurements on one of the FreeBSD.org reference
machines, building clang from scratch, with all targets enabled, and
with only the x86 target enabled. The latter was ~12% faster in real
time (on a 32-core box), and ~14% faster in user time. For a full
buildworld the difference will probably be less pronounced, though.

This works similar to WITH_SYSTEM_COMPILER added in r300354. It only
supports lld via WITH_LLD_BOOTSTRAP.
When both SYSTEM_COMPILER and SYSTEM_LINKER logic passes then libclang
will not build in cross-tools. If either check fails though then
libclang is built.
The .info is reworked to notify when libclang will be built since if
either clang or lld needs to be rebuilt, but not the other, the
notification can lead to confusion on why "clang is building".
-fuse-ld= is not used with this method so some combinations of compiler
and linker are expected to fail.
A new 'make test-system-linker' target is added to see the logic results.
Makefile.inc1:
CROSS_BINUTILS_PREFIX support had to be moved higher up so that XLD
could be set and MK_LLD_BOOTSTRAP disabled before checking SYSTEM_LINKER
logic as done with SYSTEM_COMPILER. This also required moving where
bsd.linker.mk was read since XLD needs to be set before parsing it. This
creates a situation where src.opts.mk can not test LINKER_FEATURES or
add LLD_BOOTSTAP to BROKEN_OPTIONS.
