Jung-uk Kim 874bd08821 Update SCSI opcodes and ASCs from t10.org. 
http://www.t10.org/lists/1spc-lst.htm

Note opcodes for scanner and communication devices are taken from the previous
revision because they are not listed in the files any more.
Also, note newly added ASCs are all marked with 'XXX TBD' and take SS_RDEF action
for now.  Some ASCs need SS_TUR for error recovery or SS_FATAL to prevent further
retrials.  We should deal with them later.
