implement -q to query a scsi disk for its inquiry data (vendor, model,

revision, serial #) and print that.
when the default bio ioctl fails with ENOTTY because the given disk is not
on a bio-supported raid controller, fall back to -q.
use strnvis to sanitize inquiry data so it is safe to use in scripts.
