1de7b4b805 various: general adoption of SPDX licensing ID tags.
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.

No functional change intended.

a15fbc904a Alike to r312190 decouple iSCSI connection limits from defaults.
Connection parameters should remain at defaults until negotiated.

While there, remove sythetic limits, applied if kernel provided none.
iscsid has no own limitations, no configuration and no any idea what
values are good.  Assume kernel knows what it requests.

97b84d344d Make the iSCSI parameter negotiation more flexible.
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.

82babffba9 Make it possible to set (via iscsi.conf(5)) and query (via iscsictl -v)
initiator iSCSI offload.  Pass maximum data segment size supported by
chosen offload module to iscsid(8), and make iscsid(8) not try to negotiate
anything larger than that.

8b94b5836c For both iSCSI initiator and target increase socket buffer sizes before
establishing connection.

This is a workaround for Chelsio TOE driver, that does not update socket
buffer size in hardware after connection established, and unless that is
done beforehand, kernel code will stuck, attempting to send/receive full
PDU at once.

ffe82e05b3 Make iSCSI initiator keep Initiator Session ID (ISID) across reconnects.
Previously ISID was changed every time, that made impossible correct
persistent reservation, because reconnected session was identified as
completely new one.

57a4f20b8d Make it possible for the initiator side to operate in both proxy
and normal mode; this makes it possible to compile with the former
by default, but use it only when neccessary.  That's especially
important for the userland part.

1ecb3c5857 So, it turns out SIGCHLD is discarded by default, so we have to set up
a dummy handler to make it interrupt an ioctl(2) or select(2).

This makes those short-lived iscsid(8) zombies disappear.

7843bd031a Fix several problems in the new iSCSI stack; this includes interoperability
fix for LIO (Linux target), removing possibility for the target to avoid mutual
CHAP by choosing to skip authentication altogether, and fixing truncated error
messages in iscsictl(8) output.  This also fixes several of the problems found
with Coverity.

Note that this change requires world rebuild.

Coverity CID:	1088038, 1087998, 1087990, 1088004, 1088044, 1088041, 1088040
