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.

0ac03010f6 Make delete method set via kern.cam.da.X.delete_method persistent. 
This allows to set delete method via tunable, before device capabilities
are known.  Also allow ZERO method for devices not reporting LBP, if user
explicitly requests it -- it may be useful if storage supports compression
and WRITE SAME, but does not support UNMAP.

4a3760bae6 Remove compatibility shims for legacy ATA device names. 
We got new ATA stack in FreeBSD 8.x, switched to it at 9.x, completely
removed old stack at 10.x, so at 11.x it is time to remove compat shims.

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.

0952a19f7d More aggressively fill WUT read pipeline. 
On some tests I've measured 5% copy speedup from this.

648dfc1a29 Umplement media load/eject support for removable devices. 
In case of block backend eject really closes the backing store, while
load tries to open it back.  Failed store open is reported as no media.

Now from primary node point of view requests transferred from secondary
node should look almost normal and always have valid port.

a6daea64fd Update WRITE ATOMIC(16) support to sbc4r8 draft. 
This is only a cosmetic change.  We still don't support atomic boundary
field in the CDB, but at least now we do it formally.

ca85b7c4e9 Synchronize mode pages between HA peers. 
We allow to modify only few fields in mode pages now, but still it is
not good if they unexpectedly change during failover.  Also this fixes
reporting of "Mode parameters changed" UAs on secondary node.

a85700a912 Make HA peers announce their parameters on connect. 
HA protocol requires strict version, parameters and configuration match.
Differences there may cause full set of problems up to kernel panic.
To avoid that, validate peer parameters on connect, and abort connection
immediately if some mismatch detected.

4ce7a0868c Remove duplicate and incomplete code handling LUN modify. 
Instead reuse code from LUN creation.  This allows most of LUN media
options to be changed live with modify request without full restart.

Reads and immediate writes are not blocking, so don't bother.
