This patch refactors TX immediate + response queue handling to use
the new iscsit_transport API callers, and exports the necessary
traditional iscsi PDU response creation functions for iser-target
to utilize.
This includes:
- Add iscsit_build_datain_pdu() for DATAIN PDU init + convert
iscsit_build_datain_pdu()
- Add iscsit_build_logout_rsp() for LOGOUT_RSP PDU init + convert
iscsit_send_logout()
- Add iscsit_build_nopin_rsp() for NOPIN_RSP PDU init + convert
iscsit_send_nopin()
- Add iscsit_build_rsp_pdu() for SCSI_RSP PDU init + convert
iscsit_send_response()
- Add iscsit_build_task_mgt_rsp for TM_RSP PDU init + convert
iscsit_send_task_mgt_rsp()
- Refactor immediate queue state switch into iscsit_immediate_queue()
- Convert handle_immediate_queue() to use iscsit_transport caller
- Refactor response queue state switch into iscsit_response_queue()
- Convert handle_response_queue to use iscsit_transport caller
- Export iscsit_logout_post_handler(), iscsit_increment_maxcmdsn()
and iscsit_tmr_post_handler() for external transport module usage
v5 changes:
- Fix solicited NopIN handling with RDMAExtensions=No (nab)
v3 changes:
- Add iscsit_build_reject for REJECT PDU init + convert
iscsit_send_reject()
v2 changes:
- Add iscsit_queue_rsp() for iscsit_transport->iscsit_queue_data_in()
and iscsit_transport->iscsit_queue_status()
- Update lio_queue_data_in() to use ->iscsit_queue_data_in()
- Update lio_queue_status() to use ->iscsit_queue_status()
- Use mutex_trylock() in iscsit_increment_maxcmdsn()

This reorganized the headers under include/target into:
- target_core_base.h stays as is with all target-wide data stuctures and defines
- target_core_backend.h contains the whole interface to I/O backends
- target_core_fabric.h contains the whole interface to fabric modules
Except for those only the various configfs macro headers stay around.

The Linux-iSCSI.org target module is a full featured in-kernel
software implementation of iSCSI target mode (RFC-3720) for the
current WIP mainline target v4.1 infrastructure code for the v3.1
kernel. More information can be found here:
http://linux-iscsi.org/wiki/ISCSI
This includes support for:
* RFC-3720 defined request / response state machines and support for
all defined iSCSI operation codes from Section 10.2.1.2 using libiscsi
include/scsi/iscsi_proto.h PDU definitions
* Target v4.1 compatible control plane using the generic layout in
target_core_fabric_configfs.c and fabric dependent attributes
within /sys/kernel/config/target/iscsi/ subdirectories.
* Target v4.1 compatible iSCSI statistics based on RFC-4544 (iSCSI MIBS)
* Support for IPv6 and IPv4 network portals in M:N mapping to TPGs
* iSCSI Error Recovery Hierarchy support
* Per iSCSI connection RX/TX thread pair scheduling affinity
* crc32c + crc32c_intel SSEv4 instruction offload support using libcrypto
* CHAP Authentication support using libcrypto
* Conversion to use internal SGl allocation with iscsit_alloc_buffs() ->
transport_generic_map_mem_to_cmd()
