433c583cd7 Add synchornization point in mirror log init.

it's activated for the second time.

02f6f4902f Disable partial activation for thin LVs and LVs with all missing segments
Count number of error and existing areas and if there is no existing area
for the LV avoid its activation.

Always disable partial activatio for thin volumes.

For mirrors currently put in hack to let it pass with a special name
since current mirror code needs to activate such LV during some operations.

4fb4548a57 Thin read percent info from layered device
Since we only need layered device - check for tpool device presence,

7e134dfb8e Thin clear stacked message for thin pool
Before removing thin pool LV always make sure, stacked message
for previous run are cleared - but allow to remove any
device that should have been created
(i.e. creation of snapshot failed - so the message for snapshot creation
may be replaced with delete message within unfinished transaction).

Also commit messages after lv remove - so free space is released in pool.

9142bc74bb Thin use origin_only for thin pools as well
Extend the usage of origin_only flag to allow resume of thin pool LV
(when it's active) to pass only the messages.

origin_only flag will skip detection of already resumed tree for thin_pool,
so we do not need to suspend the tree and we just send messages.

9518d362ab Thin add support for origin_only suspend of thin volumes
Pass in the origin_only flag also for thin volumes - but curently the flag
is not used to its best.

FIXME: achieve the state where only  thin volume snapshot origin is
suspended without its childrens -  let's explore whether this may
happen automatically inside libdm (might be generic for other targets).
So the code would not need to annotate the node for this.

529267fe5d Thin add messages only for activation tree
Extend lv_activate_opts with bool flag to know for which purpose
dtree is created - and add message only for activation tree
(since that's the only place that may send them).

Extend validation check for thin snapshot creation and test whether
active snapshot origin is suspended before its snapshot is created
(useful in recover scenarios) -  in this case also detect, whether
transaction has been already completed and avoid such suspend check
failure in that case.

the extension is not added.

c0f8f6270e Thin fix transaction_id incrementation and code refactoring
Add pool_has_message and use it in attach_pool_message.
Also update header to make more obvious which segment type is
expected as parameter.
Rename  'read_only' to  'no_update' (no auto update transaction_id)
to better fit how it's used.
Fix problem when there was only one stacked message replaced with delete
message that caused unwanted transaction_id increase.

cb09dc1274 Use suspend|resume_origin_only when up-converting RAID LVs, as mirrors do.
Failure to do so results in "Performing unsafe table load while X device(s) are
known to be suspended" errors.  While fixing the problem in this way works and
is consistent with the way the mirror segment type does it, it would be nice
to find a solution that uses the generic suspend/resume calls.

Also included in this check-in are additions to the test suite that perform
conversions on RAID LVs under a snapshot.  These tests are disabled for the
time being due to a kernel bug that is yet to be tracked down.

fe5199c506 Fix the way RAID meta LVs are added to the dependency tree.
Similar to the "mirror" segment type's log device, _add_dev_to_dtree should
be called and not _add_lv_to_dtree when adding metadata sub-LVs to the deptree.
Since _add_lv_to_dtree was being called, 'origin_only' could be set if a
snapshot sits on top of the RAID device.  This would cause the actual device
that needed to be added to be skipped in favor of the non-existant device,
"<foo>-real".
