f5a8b3a796 scsi: Protect against buffer possible overflow in scsi_set_sense_information 
Make sure that the input sense buffer has sufficient length
to fit the information descriptor (12 additional bytes).
Modify scsi_set_sense_information to receive the sense buffer
length and adjust its callers scsi target and libata.

(Fix patch fuzz in scsi_set_sense_information - nab)

7708c16565 scsi: Move sense handling routines to scsi_common 
Sense data handling is also done in the target stack.
Hence, move sense handling routines to scsi_common so
the target will be able to use them as well.

07e3842055 Move code that is used both by initiator and target drivers 
Move the functions that are used by both the initiator and target
subsystems into scsi_common.c/.h. This change will allow to remove
the initiator SCSI header include directives from most SCSI target
source files in a later patch.
