target: add a parse_cdb method to the backend drivers
Instead of trying to handle all SCSI command sets in one function (transport_generic_cmd_sequencer) call out to the backend driver to perform this functionality. For pSCSI a copy of the existing code is used, but for all virtual backends we can use a new parse_sbc_cdb helper is used to provide a simple SBC emulation. For now this setups means a fair amount of duplication between pSCSI and the SBC library, but patches later in this series will sort out that problem.
