check hash to the superblock. If a check hash fails when an attempt
is made to mount a filesystem, the mount fails with EINVAL (Invalid
argument). This avoids a class of filesystem panics related to
corrupted superblocks. The hash is done using crc32c.
Check hases are added only to UFS2 and not to UFS1 as UFS1 is primarily
used in embedded systems with small memories and low-powered processors
which need as light-weight a filesystem as possible.

NAT64 had compile time option IPFIREWALL_NAT64_DIRECT_OUTPUT to use

for already existing interface.
It appeared, that ifconfig(8) assumes `create` keyword as hostname and
tries to resolve it, when `ifconfig ifname create` invoked for already
existing interface. This can produce some unexpected results, when hostname
resolving has successfully happened. This patch adds check for such case.
When an interface is already exists, and create is only one argument,
return error message. But when there are some other arguments, just remove
create keyword from the arguments list.

Exiting with a signal should not be treated the same as successful exit with
zero status.
Return signal exit information to the callers via negative integers, to
enable distinction from normal exit statuses. (All consumers that check for
errors don't care what the exact non-zero exit value is -- in such a case
they print a diagnostic message and either continue or bail.)
Additionally, check for unexpected sources of waitpid() wakeup and bail if
we encounter them.

The reasons for this are forward looking to pkgbase:
* /sbin/init is a special binary; try not to replace it with
every package update because an rc script was touched.
(a follow-up commit will make init its own package)
* having rc in its own place will allow more easy replacement
of the rc framework with alternatives, such as openrc.

vermaden (maintainer of beadm) points out the following inconsistencies:
- "missing command" is not printed prior to usage if the error is simply a
missing command; this should be obvious from the context
- "bectl rename" isn't using the "don't unmount" flag (zfs rename -u), so
the active BE can't be renamed. It doesn't make sense in our context to
*not* use -u, so use it.
Documentation updates reflect the above and note an inconsistency with the
'destroy' command that is consistent with other parts of the base system.
A fix for libbe(3) not properly being installed to /lib is included.

The value of 128 chosen is a balance between being big enough to
reduce potential precision/quantization effects stemming from frequent
bucket refills over small time intervals and being small enough to
prevent a greedy driver from burst dequeuing more packets than it has
available hardware ring slots for whenever altq transitions from idle

This flag is set once the device has been successfully attached. When
set, it inhibits devmatch from trying to match the device. This in
turn allows kldunload to work as expected. Prior to the change, the
driver would immediately reload because devmatch had no notion that
