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.

Move the logic to parse volume cache commands out into a separate function
and use a loop so that multiple cache commands can be strung together on
the command line into a single update to the volume's properties.

Add the ability to manage the state of write caching when the battery
back-up is missing or dead. The current state of this field is reported
in 'mfiutil cache <volume>' and can be adjusted via
'mfiutil cache <volume> bad-bbu-write-cache <enable|disable>'. This
setting should generally be disabled to avoid data loss.

- Save errno values before calling warn(3) so that errors are correctly
reported.

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.
