reboot: Don't reboot if the next kernel isn't there

reboot -k garbage won't boot garbage unless /boot/garbage/kernel is
there. Refuse to reboot if it is missing, though allow -f to force
it for special-use cases. This is in keeping with nextboot.sh.

Add power cycle support to reboot/halt as -c.

When -c is specified, the system will be power cycled if the
underlying hardware supports it. Otherwise the system will be halted
or rebooted depending on which command was used.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same

Add flag to disable inital reboot(8) userland sync

Add -N flag to reboot(8) which bypasses the userland sync(2) during
reboot(8) while still allow the kernel sync during the reboot(2) syscall
to occur.

An example use of this is when rebooting with disconnected iSCSI sessions
which would otherwise cause the reboot to hang on BIOs that will never
complete.

Userspace part of reroot support. This makes it possible to change
the root filesystem without full reboot, using "reboot -r". This can
be used to to eg. boot from a temporary md_image preloaded by loader(8),
setup an iSCSI session, and continue booting from rootfs mounted over
iSCSI.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Add a -k option to reboot to specify the kernel to boot next time
around. If the kernel boots successfully, the record of this kernel
is erased, it is intended to be a one-shot option for testing
kernels.

This could be improved by having the loader remove the record of
the next kernel to boot, it is currently removed in /etc/rc immediately
after disks are mounted r/w.

I'd like to MFC this before the 4.6 freeze unless there is violent
objection.

Correct use of .Nm. Add rcsid. -Wall. Add -p flag in usage string (was missing).

Add support to halt, to allow it to request that the power be turned off
(the RB_POWEROFF flag)

Correct a bunch of man page cross references and generally
try and silence "manck".

ncurses, rpc, and some of the gnu stuff are still a big mess, however.

Install aliases "fasthalt" and "fastboot" for halt and boot respectively.
This is for "backwards compatibility". Documented these aliases in the
manual page.
