Admit b_blkno means block number; a block is DEV_BSIZE (a.k.a.
512) bytes; ffs is inextricably tied to using b_blkno and disklabel always uses sectorsize units. Thus use DEV_BSIZE units for all fields describing ffs filesystems and convert to/from sectors where required. This enables the creation and use of ffs filesystems on non-512 byte sectorsize devices. This diff allows i386 and sgi (the two test platforms) to find disklabels that are not on a sectorsize boundary. Same change to further archs coming. This is a no-op on 512-byte sectorsize devices. This work triggered by jsing@'s need to create ffs filesystems on sgi cdroms so we can create cdrom install media for sgi. sgi testing by jsing@ ok jsing@ pedro@ "looks sane" beck@ weingart@
