  - bring opcode names, asc/ascq strings and sense format
    into line with SPC-3 rev 21 (22 September 2004)
  - drop SCSI-1 sense buffer decoding [still output it in hex]
  - opcode names include those that depend on service actions
    including variable length commands **
  - decodes both fixed and descriptor sense data formats
  - use KERN_INFO on printk()s that start on new lines
  - flag vendor specific asc and acsq codes
  - print all bytes of a cdb after the name (previously skipped
    the first byte)
