include sys/time.h instead of time.h. This include is incorrect as
per the manpages for the APIs and the POSIX definitions. This commit
replaces sys/time.h where necessary with time.h.
The commit also includes some minor style(9) header fixup in newfs.
This commit is part of a larger effort by Garrett Cooper started in
//depot/user/gcooper/posix-conformance-work/ -- to make FreeBSD more
POSIX compliant.

It does not make sense to shut down daemons that were not started. In
particular, this fixes loss of mixer settings when shutting down using
shutdown(8), init(8) or ctrl+alt+del from single-user mode.
If /etc/rc reboots, /etc/rc.shutdown is not run.
Also fix segfaults and other erratic behaviour if init receives SIGHUP or
SIGTSTP while in single-user mode.
This commit does not attempt to fix any badness with signal handlers
(assumption that pointers can be read and written atomically, EINTR race
condition). I believe it does not make this badness any worse.
Silence on: -arch@
by the MBR for the given parameter and set that parameter to the
maximum value instead of just truncating the most significant part
silently.
Could happen for example if the capacity of the device is more
than 2TB, so that the number of sectors is greater than 2Mib.

reading. (This was already done for writing to a sysctl). This
requires all SYSCTL setups to specify a type. Most of them are now
checked at compile-time.
Remove SYSCTL_*X* sysctl additions as the print being in hex should be
controlled by the -x flag to sysctl(8).

signal action is restored to default in child after fork(2).
In this case there is no need to do anything with dummy SIGCHLD handler,
because after fork(2) it will be automatically reverted to SIG_IGN.

It is possible that the parent process ignores some of them and sigtimedwait()
will never see them, eventhough they are masked.
The most common situation for this to happen is boot process where init(8)
ignores SIGHUP before starting to execute /etc/rc. This in turn caused
hastd(8) to ignore SIGHUP.

counterpart also takes, i.e. "fdx" for "full-duplex", "flow" for
"flowcontrol", "hdx" for "half-duplex" as well as "loop" and "loopback"
for "hw-loopback".

It is implemented as a hard link to shutdown(8) and it is equivalent of:
# shutdown -p now
While I'm here put one line of usage into one line of C code so it is easier to
grep(1) and separate unrelated code with empty line.

more useful information. Instead of:
hastd: remote address not configured for resource foo
Print the following:
No resource foo configuration for this node (acceptable node names: freefall, freefall.freebsd.org, 44333332-4c44-4e31-4a30-313920202020).

camcontrol.c: In buildbusdevlist(), don't attempt to get call
getdevid() for an unconfigured device, even when the
verbose flag is set. The cam_open_btl() call will almost
certainly fail.
Probe for the buffer size when issuing the XPT_GDEV_ADVINFO
CCB. Probing for the buffer size first helps us avoid
allocating the maximum buffer size when it really may not
be necessary. This also helps avoid errors from
cam_periph_mapmem() if we attempt to map more than MAXPHYS.
cam_periph.c: In cam_periph_mapmem(), if the XPT_GDEV_ADVINFO CCB
shows a bufsiz of 0, we don't have anything to map,
so just return.
Also, set the maximum mapping size to MAXPHYS
instead of DFLTPHYS for XPT_GDEV_ADVINFO CCBs,
since they don't actually go down to the hardware.
scsi_pass.c: Don't bother mapping the buffer in XPT_GDEV_ADVINFO
CCBs if bufsiz is 0.
