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.

This will disable the new LLVM_TARGET_ALL option which will only
enable the required target.
This only impacts the bootstrap compiler in WORLDTMP, not the target compiler
that will be installed.

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.

Currently libclang_rt is not provided for cross-building and as such
is not connected to cross-tools. For building clang once in universe
it is likely that libclang_rt won't exist for the universe toolchain
but even if it did it would not support anything but the native arch.
So explicitly check for support before enabling h_raw.

Previously the linuxulator's linux_brk invoked the FreeBSD sys_break
syscall implementation directly. Instead, move the bulk of the existing
implementation to kern_break, and call that from both sys_break and
linux_brk.
This also addresses a minor bug in linux_brk in that we now return the
actual (rounded up) break address, rather than the requested value.

We have a problem with vn_fullpath_global when the file exists. Work
around it by printing the full path if the core file name starts with /,
or current working directory followed by the filename if not.

While useful as an example, veriexecctl, as it is, has very little practical
use, since there is nothing ensuring the integrity of the manifest of hashes.
A more appropriate set of utilities will replace it.
Tested syscalls include rfork(2), chdir(2), fchdir(2), chroot(2),
getresuid(2), getresgid(2), setpriority(2), setgroups(2), setpgrp(2),
setrlimit(2), setlogin(2), mlock(2), munlock(2), minherit(2), rtprio(2),
profil(2), ktrace(2), ptrace(2), fork(2), umask(2), setuid(2), setgid(2),
seteuid(2), and setegid(2). The last six are only tested in the success
case, either because they're infalliable or a failure is difficult to cause
on-demand.

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"

lock order reversal: (sleepable after non-sleepable)
1st 0xfffffe00357ff538 xnb_softc (xen netback softc lock) @ /usr/src/sys/dev/xen/netback/netback.c:1069
2nd 0xffffffff81fdccb0 intrsrc (intrsrc) @ /usr/src/sys/x86/x86/intr_machdep.c:224
There's no need to hold the lock since the cleaning of the interrupt
cannot happen in parallel due to the XNBF_IN_SHUTDOWN flag being set.
Note that the locking in netback needs some improvement or
clarification.
While there also remove a double newline.

As previously noted, kernel's processing of these means that the first
appearance of a hint/variable wins. Flipping the order of concatenation
means that later variables override earlier variables, as expected when one
does:
hints x
hints y
Where perhaps x is:
hint.aw_sid.0.disable=1
and y is:
hint.aw_sid.0.disable=0
The expectation would be that a later appearing variable would override an
earlier appearing variable, such as with `device`/`nodevice`, device.hints,
and other similarly structured data files.
Previously, only one 'env' file could be specified. Later 'env' directives
would overwrite earlier 'env' directives. This is inconsistent with every
other file-accepting directives which process files in order, including
hints.
A caveat applies to both hints and env that isn't mentioned: they're
concatenated in the order of appearance, so they're not actually applied in
the way one might think by supplying:
hints x
hints y
Hints in x will take precedence over same-name hints in y due to how
the kernel processes them, stopping at the first line that matches the hint
we're searching for. Future work will flip the order of concatenation so
that later files may still properly override earlier files.
In practice, this likely doesn't matter at all due to the nature of the
beast.
The reference counting that's done in the geom_vfs layer to prevent
delivery of requests to defunct devices only works if all requests go
through that layer. UFS was bypassing that layer for BIO_DELETE requests,
sending them to the geom_consumer directly with g_io_request. Allocate
a buf, fill it in, and call strategy on it instead.
