IFC to head to catch up the bhyve branch

Approved by: grehan@

Let reboot(8) use getprogname() to compare the program name.

While there, mark the global variable dohalt static, as reboot(8) only
consists of a single C file.

IFH@204581

Port the remaining apps in sbin/ to utmpx; only reboot(8).

Merge from head at r201628.

# This hasn't been tested, and there are at least three bad commits
# that need to be backed out before the branch will be stable again.

Add forgotten `void' keyword. This function has no arguments.

Let init(8) and reboot(8) use utmpx to log wtmp entries.

Let init(8) and reboot(8) use utmpx to log wtmp entries.

logwtmp() gets called with the raw strings that are written to disk. For
regular user entries, this isn't too bad, but when booting/shutting
down, the contents get rather cryptic.

Just call the standardized pututxline().

The kernel specified in main() of reboot(8) will be initialized
with -k option and never be used without kflag. This confuses
gcc because we set "kflag" at the same time with "kernel", but
the logic is not that apparant for gcc.

Since we can initialize "kernel" to NULL then know if "k" option
is set through determining whether it is still NULL, don't try
to have gcc to guess why we are connecting "kflag" with "kernel"
and use "kernel" directly in place of kflag.

When kill(-1) returns ESRCH, it could be because the current process
doesn't have a process group, which can occur if you're working with
a custom init that doesn't set up a full tty context. Rather than
refusing to reboot, ignore ESRCH from the kill attempt in reboot(8).

Set only the RB_POWEROFF flag (not the RB_HALT flag) when
'-p' is used on the reboot(8) command line.

This is intended for use when you want to attempt a power down
action, but you want the system to reboot (not halt) if the
power down action fails.

This is typically useful when the power-off action performed by
the kernel consists in signalling an uninterrupted power supply
that it should shut down its inverter if mains power has not returned.

The behaviour of shutdown(8) and init(8) is not modified;
only the behaviour of invoking 'reboot -p' manually is
modified, and then only in the case when a power-down action
fails.

Correct the file that reboot -k creates so that it works with the new
nextboot functionality.

Reviewed by: jake (mentor)

Rename the file used to specify the nextboot to make it clear that this
is a loader configuration file and can be used for more than just a
kernel name.
