Libiscsi: Introducing new functions for zero-copy write operations

Browse Source 
iscsi-command:  Adding new functions for all write operations (WRITE10,
                WRITE12, WRITE16, WRITEOR, etc') for cases where the user wants
                to pass his own io vectors (prevent memcpy).

                new functions are called iscsi_write*_iov_task and looks
                very similar to the iscsi_write*_task, only they get
		scsi_iovec pointer and number of scsi_iovec as
		parameters.
