While it could be preferred to do this at insert in libbe(3), there's no
convenient way to insert at the head of an nvlist. Instead, we'll make two
passes over- once to print anything active either now or at nextboot, and
another to print everything else.
This doesn't actually impact performance in a significant way here, so we'll
worry about further optimizations if the need actually arises.
bectl list -a should show the boot environment, its relevant dataset, and
the snapshot it was created from. The header also changes to indicate the
rough order in which these things will show.
While here, start doing a little bit of spring cleaning and splitting
different bits out.
The timespecadd(3) family of macros were imported from NetBSD back in
r35029. However, they were initially guarded by #ifdef _KERNEL. In the
meantime, we have grown at least 28 syscalls that use timespecs in some
way, leading many programs both inside and outside of the base system to
redefine those macros. It's better just to make the definitions public.
Our kernel currently defines two-argument versions of timespecadd and
timespecsub. NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define
three-argument versions. Solaris also defines a three-argument version, but
only in its kernel. This revision changes our definition to match the
common three-argument version.
Bump _FreeBSD_version due to the breaking KPI change.

The jail is created with allow.mount, allow.mount.devfs, and
enforce_statfs=1. Upon creation, we immediately attach, chdir to "/", and
drop the user into a shell inside the jail.
The default IP for this is arbitrarily 10.20.30.40.
The given parameter may either be a jid, jail name, or a BE name. In all
cases, the parameter will be resolved to a jid and bectl(8) will
sanity-check that there's actually a BE mounted at the requested jail root
before invoking jail_remove(2).
Based on the idea that we shouldn't have all-new library and utility going
into base that need WARNS=1...

For the moment, this is a primitive nvlist dump of what we get back from
be_get_bootenv_props as a proof-of-concept and to make sure that we're
getting back the kind of information we want to see from list.
This check eliminates infinite loop of MTU change / link flap / lease verification / MTU change / link flap etc.
in case of some NIC drivers like em(4) or igb(4).
N.B.: obsolete u_int16_t is used in consistency with the rest of the file.

"record-state" is similar to "keep-state", but it doesn't produce implicit
O_PROBE_STATE opcode in a rule. "set-limit" is like "limit", but it has the
same feature as "record-state", it is single opcode without implicit
O_PROBE_STATE opcode. "defer-action" is targeted to be used with dynamic
states. When rule with this opcode is matched, the rule's action will
not be executed, instead dynamic state will be created. And when this
state will be matched by "check-state", then rule action will be executed.
This allows create a more complicated rulesets.

Currently ifconfig(8) only prints the hex representation of ssid names
with non-ASCII characters. Many modern terminals are able to properly render
non-ASCII characters. This change checks if the terminal charmap is UTF-8,
and if so, will render the characters, rather than the hex value.
This behavior is circumvented by running ifconfig(8) in a non-UTF8 locale;
e.g. C or POSIX.
It was pointed out by kp@ during the review that APs have the option to
broadcast whether their SSIDs may be interpreted as UTF-8. Ideally, we would
honor this and only attempt this behavior if it's so-broadcasted by the AP.
However, a sample survey showed that hostapd will advertise this if
indicated in config but it doesn't seem to be so common in the AP market, so
this would be effectively useless as we'll rarely know if the SSID should be
renderable as UTF-8.
Despite this, it was decided to be OK with this anyways- there's a
straightforward path to doing it the right way based on advertisement by AP
if we need to go that route, and one can revert to old behavior easily
enough at runtime if we get it wrong.
