The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

As is done in the target, require that DataSN values are consecutive
and in-order. If an out of order Data-In PDU is received, force a
session reconnect. In addition, when a SCSI Response PDU is received,
verify that the ExpDataSN field matches the count of Data-In PDUs
received for this command. If not, force a session reconnect.

This fixes a few bugs in iSCSI backends where the backends were using
the limits they advertised initially during the login phase as the
final values instead of the values negotiated with the other end.

DataSN for solicited Data-Out is per-R2T. Since we handle whole R2T
in one go, we don't need to store it anywhere, especially in global
per-command structure. This may allow us to handle multiple R2T per
command at once, if we decide, or may be relax locking.
Rename the second use of that field to io_referenced_task_tag.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Decouple the send and receive limits on the amount of data in a single
iSCSI PDU. MaxRecvDataSegmentLength is declarative, not negotiated, and
is direction-specific so there is no reason for both ends to limit
themselves to the same min(initiator, target) value in both directions.
Allow iSCSI drivers to report their send, receive, first burst, and max
burst limits explicitly instead of using hardcoded values or trying to
derive all of them from the receive limit (which was the only limit
reported by the drivers prior to this change).
Display the send and receive limits separately in the userspace iSCSI
utilities.

Ensure that all iSCSI sessions are correctly terminated during shutdown.
* Enhances the changes done by r286226 (D3052).
* Add shutdown post sync event to run after filesystem shutdown
(SHUTDOWN_PRI_FIRST) but before CAM shutdown (SHUTDOWN_PRI_DEFAULT).
* Changes iscsi_maintenance_thread to processes terminate in preference to
reconnect.

Previously ISID was changed every time, that made impossible correct
persistent reservation, because reconnected session was identified as
completely new one.
