- Do not include a NetBSD header as it is not needed anymore.

Browse Source 
- Remove two constants that were needed in conjuction with the
   NetBSD disklabel header.  Use the FreeBSD equivalents.
   To boot from NetBSD/sparc64 partitions, define LABELOFFSET to
   be 128.
 - Do not use the complete open firmware path to filter out cdrom drives.
   No path containing "cdrom" is detected as a disk now.
 - Simplify some code.
