SCSI fixes on 20131206 

This is a set of nine fixes (and one author update). The libsas one should fix
 discovery in eSATA devices, the WRITE_SAME one is the largest, but it should
 fix a lot of problems we've been getting with the emulated RAID devices
 (they've been effectively lying about support and then firmware has been
 choking on the commands).  The rest are various crash, hang or warn driver
 fixes.
