Add mrsasutil(8) as alias to mfiutil(8)

mfiutil(8) in theory can work on devices attached to mrsas(4) but
mrsas(4) is missing the FreeBSD mfi(4) ioctl support. Once that
support is added to mrsas(4) then mrsasutil(8) can manage mrsas(4)
attached devices. So this commit depends on that. When mrsasutil(8)
is run it automatically opens /dev/mrsas0 instead of /dev/mfi0.
Add -D <device> and -t <type> flag to optionally specify mrsas or mfi to
work with the existing -u <unit>. Device is the device node with or
without /dev/

Add support for getting and setting BBU properties related to battery
relearning. Specifically, add subcommands to mfiutil(8) which allow the
user to set the BBU and autolearn modes when the firmware supports it,
and add a subcommand which kicks off a battery relearn.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

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.

Fixed dependencies (make checkdpadd).

Merge mfiutil

Move mfiutil.1 to mfiutil.8 for consistency. Remove superfulous README.

ntroduce mfiutil, a basic utility for managing LSI SAS-RAID & Dell PERC5/6
controllers. Controller, array, and drive status can be checked, basic
attributes can be changed, and arrays and spares can be created and deleted.
Controller firmware can also be flashed.

This does not replace MegaCLI, found in ports, as that is officially sanctioned
and supported by LSI and includes vastly more functionality. However, mfiutil
is open source and guaranteed to provide basic functionality, which can be
especially useful if you have a problem and can't get MegaCLI to work.
