Add a script that allows software RAID sets to be created before file

systems are mounted.  An example set of entries for /etc/rc.conf:

ataraid_enable="YES"
ataraid_devices="ar0"
ataraid_ar0_set="ad2 ad3"
ataraid_ar0_type="RAID1"

Because there is no "correct" way of doing ATA raid (ie, geom vs.
atacontrol vs. vinum) that is bikeshed proof, this rcng script stays within
the bounds of atacontrol and assumes that other RAID solutions for GEOM or
vinum will end up in a different rcNG script.
