Use __DECONST (instead of my own attempted re-invention) for the iov
parameters to jail_get/set(2). Similarly remove the decost-ish hack
from execvp's argv, except the __DECONST is only added at very end.
While I'm at it, remove an unused variable and fix a comment typo.

Since tm::tm_gmtoff is a long, use labs(3) instead.

2 errors generated.
These warnings occur because both preferred_time and pfx_pltimeexpire
are uint32_t's, so the subtraction expression is also unsigned, and
calling abs() is a no-op.
However, the intention was to look at the absolute difference between
the two unsigned quantities. Introduce a small static function to
clarify what we're doing, and call that instead.

Previously, we have a nap interval of 1 second while we have a timeout of
128 seconds by default, which could be an overkill, and for some hardware
the patting action may be expensive.
Note that the choice of nap interval is still arbitrary. We preferred
a safe value where even when the system is very heavily loaded, the
watchdog should not shoot the system down if it's not really hung.
According to the manual page of Linux's watchdog daemon, the nap interval
time of theirs is 10 seconds, which seems to be a reasonable value --
according to Intel documentation AP-725 (Document Number: 292273-001),
ICH5's maximum timeout is about 37.5 seconds, which the ichwd(4) driver
would set when we requested 128 seconds (although it should probably
feed back this as an error and do not set the timeout). Since that's
the shortest maximum value, 10 seconds seems to be a right choice for
us too.

have chosen different (and more traditional) stateless/statuful
NAT64 as translation mechanism. Last non-trivial commits to both
faith(4) and faithd(8) happened more than 12 years ago, so I assume
it is time to drop RFC3142 in FreeBSD.
No objections from: net@
While all tested initiators and targets use hex-encoded CHAP data, RFC also
allows base64 encoding there, and Microsoft certificaition tool uses it.
