SCSI fixes on 20130412

Browse Source 
This is a set of ten bug fixes (and two consisting of copyright year update
 and version number change) pretty much all of which involve either a crash or
 a hang except the removal of the random sleep from the qla2xxx driver (which
 is a coding error so bad, we want it gone before anyone has a chance to copy
 it).
