iscsi: Fetch limits based on a socket rather than assuming global limits.

cxgbei needs the ability to return different limits based on the
connection (e.g. if the connection is over a T5 adapter or a T6
adapter as well as factoring in the MTU).

This change plumbs through the changes in the ioctls without changing
any of the backends. The limits callback passed to icl_register now
accepts a second socket argument which holds the integer file
descriptor. To support ABI compatiblity for old binaries, the
callback should return "global" values if the socket fd is zero.

The CTL_ISCSI_LIMITS argument used with CTL_ISCSI by ctld(8) now
accepts the socket fd in a field that was previously part of a
reserved spare field. Old binaries zero this request which results in
passing a socket fd of 0 to the limits callback.

The ISCSIDREQUEST ioctl no longer returns limits. Instead, iscsid(8)
invokes a new ISCSIDLIMITS ioctl after establishing the connection via
connect(2). For ABI compat, if the old ISCSIDREQUEST is invoked, the
global limits are still fetched (with a socket fd of 0) and returned.

sys/dev: further 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.

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.
