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/

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Don't claim the adapter is idle if it is clearing a drive.

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.

Decode new battery status indications.

Improve battery capacity reporting

When a status pointer is passed in mfi_dcmd_command does not return an
errno (if the ioctl is successful), so move the test for NO_HW_PRESENT
outside of the error case. This should fix incorrect reporting for
systems with a dead or no battery.

Additionally, handle error codes other than NO_HW_PRESENT by omitting
the battery capacity display. LSI's supercap-based parts (CV series)
report their data using the same interface as battery-based parts,
except that they do not include the capacity stats (state of charge,
cumulative charge cycles, etc.)

A new jail(8) with a configuration file, to replace the work currently done

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.

Merge mfiutil

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.
