As part of the test also validate the PDU that libiscsi generates and verify that
1, the PDU we send has the F flag set
2, that datasegmentlength for the PDU is one block
so that i/o from the initiator stops flowing and are just queued locally
until teh cmdsn window opens up again.
Send a lot of writes that block until we have processed the R2T
back from the target and verify we can still make process when we
have saturated the cmdsn window and are also blocked waiting for R2Ts.

For now the global initiator is renamed to initiatorname1 (and initiator2 is
renamed to initiatorname2, respectively), but ultimately the globals should
probably go away.
While fixing this it also became apparent that initiator-name-2 was parsed
into the "initiator" variable as well.

Send a large number of DATA-OUT PDUs that do not have a matching SCSI-COMMAND
PDU and verify that the target responds correctly. Either by terminating the
session or by just ignoring the data.
Verify also that the target is not "surprised" and crashes.

Add a test for the standard INQUIRY data. The iscsi/scsi target should complete
the request successfully for all values of buffersize/allocation_length
of 1 to 255 bytes.

Teach the test harness to distinguish skipped tests from failed tests.
Return -2 from a skipped test and, if no test was failed but some were
skipped, return 77 from the main program.

Send a write containing two DATA-IN PDUs in a sequence but both PDUs have DATASN==0
This is an error and the target should react to this as an invalid command
