f82829966f 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.

9545bdb164 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.

1fd9c17d05 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.

fb08575948 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.

9e5012814b 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.

4c00714c1f 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.

6711ffe0ce 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.

options to be changed live with modify request without full restart.

mav
ce8faf1ce9 Always execute REPORT LUNS and REQUEST SENSE commands locally.
REPORT LUNS command is more related to target rather then specific LUN.
This node may be primary for LUNs for some reason unknown to another,
and command forwarded to another node won't be able to report them.

REQUEST SENSE is related to LUN, but in our implementation it reports
only UAs and CAs, that are stored locally rather then on primary node.
