agc 33645f4ad2 Import the distribution files for the iSCSI target, developed from the 
original Intel code (BSD-licensed) in othersrc, by myself.

This provides an iSCSI target implementation in userland, as well as a
test harness which also runs in userland.

The iSCSI target has been tested with version 1.06 of the Microsoft
initiator, as well as with its own test harness.
