96b5475b7a Pass task management response information from CTL through CAM to isp(4), 
utilizing previously unused arg field of struct ccb_notify_acknowledge.

This makes new QUERY TASK, QUERY TASK SET and QUERY ASYNC EVENT requests
really functional for CAM target mode drivers.

167e63e394 cam: unsign some types to match their definitions and avoid overflows. 
numpatterns is u_int.

ctl:
CTL_NUM_MODE_PAGES comes from sizeof().
In struct:ctl_scsiio, kern_sg_entries is uint32_t.

3616095801 Fix style issues around existing SDT probes. 
- Use SDT_PROBE<N>() instead of SDT_PROBE(). This has no functional effect
  at the moment, but will be needed for some future changes.
- Don't hardcode the module component of the probe identifier. This is
  set automatically by the SDT framework.

6bd364b523 Modify target port groups logic in CTL. 
- Introduce "ha_shared" port option, which being set to "on" moves the
port into separate port group, shared between HA nodes.  This allows to
better handle cases when iSCSI portals are bound to CARP address that can
dynamically move between nodes.  Some initiators (at least VMware) don't
detect that after iSCSI reconnect they've attached to different SCSI port
from different port group, that totally breakes ALUA status parsing.
In theory, I believe, it should be enough to have different iSCSI portal
group tags on different nodes to make initiators detect this condition,
but it seems like VMware ignores those values, and even full LUN retaste
forced by UA does not help.
 - Make CTL report up to three port groups: 1 -- non-HA mode or ports
with "ha_shared" option set, 2 -- HA node 1, 3 -- HA node 2.
 - Report Transitioning state for all port groups when HA interlink is
connected, but neither of nodes is primary for the LUN.

59f063d549 Give CTL support for PIM_EXTLUNS when talking to CAM. 
CTL itself still lives in flat LUN space, but it can generate extended
numbers if CAM SIM reports such capability.

c98d2b1f1e Add partial support for QUERY TMF to CAM and isp(4). 
This change allows to decode respective functions in isp(4) in target mode
and pass them through CAM to CTL.  Unfortunately neither CAM nor isp(4)
support returning response info for those task management functions now.

On the other side I just have no initiator to test this functionality.

361e885315 Remove lock upgrade attempt from ctl_be_block_open_file(). 
I am not sure what for it was done.  Now open routine should automatically
fall back to read-only if open for writing is impossible.  In such case
attempt to upgrade to write sounds strange.
