Some code reorganization.

- Remove code duplication by adding two new functions to execute prepared
queue entry via either mbox or request queue and wait for result.
- Since the new function executing via request queue sleeps any way, make
it sleep also in case of overflows or handle shortages. It should make it
more reliable and less affecting other less flexible request queue users.
- Turn isp_target_put_entry() into not target-specific isp_send_entry().
- Make handling of responses with control handles more universal.
- Move RQSTYPE_RPT_ID_ACQ handling into new function.
- Inline isp_handle_other_response(), becoming trivial after above.
- Clean the list of IOCBs from pre-24xx ones.

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.

MISC CHANGES

Add a new async event- ISP_TARGET_NOTIFY_ACK, that will guarantee
eventual delivery of a NOTIFY ACK. This is tons better than just
ignoring the return from isp_notify_ack and hoping for the best.

Clean up the lower level lun enable code to be a bit more sensible.

Fix a botch in isp_endcmd which was messing up the sense data.

Fix notify ack for SRR to use a sensible error code in the case
of a reject.

Clean up and make clear what kind of firmware we've loaded and
what capabilities it has.
-----------
FULL (252 byte) SENSE DATA

In CTIOs for the ISP, there's only a limimted amount of space
to load SENSE DATA for associated CHECK CONDITIONS (24 or 26
bytes). This makes it difficult to send full SENSE DATA that can
be up to 252 bytes.

Implement MODE 2 responses which have us build the FCP Response
in system memory which the ISP will put onto the wire directly.

On the initiator side, the same problem occurs in that a command
status response only has a limited amount of space for SENSE DATA.
This data is supplemented by status continuation responses that
the ISP pushes onto the response queue after the status response.
We now pull them all together so that full sense data can be
returned to the periph driver.

This is supported on 23XX, 24XX and 25XX cards.

This is also preparation for doing >16 byte CDBs.

-----------
FC TAPE

Implement full FC-TAPE on both initiator and target mode side. This
capability is driven by firmware loaded, board type, board NVRAM
settings, or hint configuration options to enable or disable. This
is supported for 23XX, 24XX and 25XX cards.

On the initiator side, we pretty much just have to generate a command
reference number for each command we send out. This is FCP-4 compliant
in that we do this per ITL nexus to generate the allowed 1 thru 255
CRN.

In order to support the target side of FC-TAPE, we now pay attention
to more of the PRLI word 3 parameters which will tell us whether
an initiator wants confirmed responses. While we're at it, we'll
pay attention to the initiator view too and report it.

On sending back CTIOs, we will notice whether the initiator wants
confirmed responses and we'll set up flags to do so.

If a response or data frame is lost the initiator sends us an SRR
(Sequence Retransmit Request) ELS which shows up as an SRR notify
and all outstanding CTIOs are nuked with SRR Received status. The
SRR notify contains the offset that the initiator wants us to restart
the data transfer from or to retransmit the response frame.

If the ISP driver still has the CCB around for which the data segment
or response applies, it will retransmit.

However, we typically don't know about a lost data frame until we
send the FCP Response and the initiator totes up counters for data
moved and notices missing segments. In this case we've already
completed the data CCBs already and sent themn back up to the periph
driver. Because there's no really clean mechanism yet in CAM to
handle this, a hack has been put into place to complete the CTIO
CCB with the CAM_MESSAGE_RECV status which will have a MODIFY DATA
POINTER extended message in it. The internal ISP target groks this
and ctl(8) will be modified to deal with this as well.

At any rate, the data is retransmitted and an an FCP response is
sent. The whole point here is to successfully complete a command
so that you don't have to depend on ULP (SCSI) to have to recover,
which in the case of tape is not really possible (hence the name
FC-TAPE).

to getting rid u_int for uint and so on).

First of several commits as this driver is dusted off and maybe brought
up to date. Principle changes for this reelase is to support 2K Port Login
firmware. This allows us to support the 2322 (and 2422 4Gb) cards which only
come with the 2K Port Login firmware. The 2322 should now work- but we don't
have firmware sets for it in ispfw (as the change to load 2K Port Login f/w
hasn't been made- that f/w is so big it has to be loaded in more than one
chunk).

Other changes are the beginnings of cleaning up some long standing target
mode issues. The next changes here will incorporate a lot of bug fixes
from others.

Finally, some copyright cleanup and attempts to make the parts of the
driver that are FreeBSD specific start conforming more to FreeBSD style.
