I'm still working on bidirectional support.  It's held up as I'm
having initiator issues, making it somewhat hard to test.

But the extended CDB and AHS handling should be okay, as well as
returning data and sense.  Let me know if you'd like any changes
to these next four.

01 track-target-type
	Trivial, need this to switch on target type in scsi.c
	eventually.

02 pass-scb-length
	Give length of CDB to target.

03 parse-iscsi-ahs-header-for-ext
	iscsi: parse AHS and handle extended CDB.

04 return-sense-data-in-iscsi-res
	Return sense data separate from requsted data.  May want
	to fix tgtif to hand it back into kernel too sometime.
