--color may be set to one of: 'auto', 'always', and 'never'.
'auto' is the default behavior- output colors only if -G or COLORTERM are
set, and only if stdout is a tty.
'always' is a new behavior- output colors always. termcap(5) will be
consulted unless TERM is unset or not a recognized terminal, in which case
ls(1) will fall back to explicitly outputting ANSI escape sequences.
'never' to turn off any environment variable and -G usage.

Summary:
PowerISA 3.0 adds a 'darn' instruction to "deliver a random number". This
driver was modeled after (rather, copied and gutted of) the Ivy Bridge
rdrand driver.
This uses the "Conditional Random Number" behavior to remove input bias.
From the ISA reference the 'darn' instruction, and the random number
generator backing it, conforms to the NIST SP800-90B and SP800-90C
standards, compliant to the extent possible at the time the hardware was
designed, and guarantees a minimum 0.5 bits of entropy per bit returned.

This change allows one to set kern.boot_tag="" and not get a blank line
preceding other boot messages. While this isn't super critical- blank lines
are easy to filter out both mentally and in processing dmesg later- it
allows for a mode of operation that matches previous behavior.
I intend to MFC this whole series to stable/11 by the end of the month with
boot_tag empty by default to make this effectively a nop in the stable
branch.
Adding batch mode to the jail `bectl(8)` subcommand enables jailing of
ZFS Boot Environments in a scriptable fashion.

The wrapper is a thin shim around libsodium's Poly-1305 implementation. For
now, we just use the C algorithm and do not attempt to build the
SSE-optimized variant for x86 processors.
The algorithm support has not yet been plumbed through cryptodev, or added
to cryptosoft.
The idea is untouched upstream sources live in sys/contrib/libsodium.
sys/crypto/libsodium are support routines or compatibility headers to allow
building unmodified upstream code.
This is not yet integrated into the build system, so no functional change.
Bring in https://github.com/jedisct1/libsodium at
461ac93b260b91db8ad957f5a576860e3e9c88a1 (August 7, 2018), unmodified.
libsodium is derived from Daniel J. Bernstein et al.'s 2011 NaCl
("Networking and Cryptography Library," pronounced "salt") software library.
At the risk of oversimplifying, libsodium primarily exists to make it easier
to use NaCl. NaCl and libsodium provide high quality implementations of a
number of useful cryptographic concepts (as well as the underlying
primitics) seeing some adoption in newer network protocols.
I considered but dismissed cleaning up the directory hierarchy and
discarding artifacts of other build systems in favor of remaining close to
upstream (and easing future updates).
Nothing is integrated into the build system yet, so in that sense, no
functional change.
Two of these testcases require software crypto to be enabled. Curiously, it
isn't by default.

FreeBSD's mkstemp sets the temporary file's permissions to 600, and has ever
since mkstemp was added in 1987. Coverity's warning is still relevant for
portable programs since OpenGroup does not require that behavior, and POSIX
didn't until 2008. But none of these programs are portable.
umask(2) should always be used prior to mkstemp(3) so the temporary file
won't be created with insecure permissions.

Previously, we only validated names for character restrictions. This is
helpful, but we should've also checked length restrictions- dataset names
must be restricted to MAXNAMELEN.
While here, move validation before doing a bunch of concatenations and fix
error handling in be_rename. It was previously setting the error state based
on return value from a libzfs function, which is wrong: libzfs errors don't
necessarily match cleanly to libbe errors. This would cause the assertion in
be_error to hit when the error was printed.
jails since FreeBSD 7.
Along with the system call, put the various security.jail.allow_foo and
security.jail.foo_allowed sysctls partly under COMPAT_FREEBSD11 (or
BURN_BRIDGES). These sysctls had two disparate uses: on the system side,
they were global permissions for jails created via jail(2) which lacked
fine-grained permission controls; inside a jail, they're read-only
descriptions of what the current jail is allowed to do. The first use
is obsolete along with jail(2), but keep them for the second-read-only use.

The fix is only partial and causes an asymmetry which breaks a test in
multi_test.sh.
We should consider both parts of the issue found in OpenBSD[1], but for now
just revert the change.

lld should now be a usable linker for armv7, and is already used as the
bootstrap linker (for linking the kernel and userland). Also enable as
the system linker now (/usr/bin/ld) for further testing and evaluation.
