Text requests and responses can span multiple PDUs. In that case, the sender sets the Continue bit in non-final PDUs and the Final bit in the last PDU. The receiver responds to non-final PDUs with an empty text PDU. To support this, add a more abstract API in libiscsi which accepts and receives key sets rather than PDUs. These routines internally send or receive one or more PDUs. Use these new functions to replace the handling of TextRequest and TextResponse PDUs in discovery sessions in both ctld and iscsid. Note that there is not currently a use case for large Text requests and those are still always sent as a single PDU. However, discovery sessions can return a text response listing targets that spans multiple PDUs, so the new API supports sending and receiving multi-PDU responses.
