b65a9230a3 lvmdbusd: Update state during pv move
Periodically update the state during pv move so that all the different
dbus objects reflect something close to reality during the process.

3ead4fb7ac lvmdbusd: Limit state refreshes for udev events
Udev events can come in like a flood when something changes.  It really
doesn't do us any good to refresh the state of the service numerous times
when 1 would suffice.  We had something like this before, but it was
removed when we added the refresh thread.  However, we have since learned
that we need to sequence events in the correct order and block dbus
operations if we believe the state has been affected, thus udev events are
being processed on the main work queue.  This change limits spurious
work items from getting to the queue.

7eeb093fdd lvmdbusd: Call add_no_notify for *move commands
Missed this in change when "add_no_notify" was added.  This was causing
extra external events to process when we did moves.

2dc71fc291 lvmdbusd: Only disable notify_dbus after getting external event
If we always disable the sending of notify dbus events then in the case
where all the users are lvm dbus users we will be in udev handling mode
until at least 1 external lvm command occurs.  Instead we will not disable
notify dbus until after we get at least 1 external event.  This makes the
service get into the correct mode of operation faster.

17b56a4aed tests: early detect leaking error dev
lvconvert should not leak 'error' device.

(This patch is not fix the problem, just makes it more easily visible
instead of more confusing 'clvmd' trace).

07ea9887d3 tests: raise min dm cache version
Since we want to test different cache policies with profiles mq&smq
raise version to 1.8.

TODO: maybe split in more tests so older targets can test here as well.
N.B.: passthrough is also not supported with version 1.3

4a271e7ee7 properties: only thin-pool provides discards
Quering non-thin-pool segment for discard property may lead
to intenal error if the segment had set 'out-of-range' value,
so only thin-pool is allowed, for other it returns NULL.

17bee733d1 raid: conditionally reject convert to striped/raid0*
If SubLVs to be removed still exist after an image removing
conversion (i.e. "lvconvert --yes --force --stripes N "
with N < total stripes) any request to convert to a different
striped/raid* level has to be rejected until after those freed
SubLVs got removed by running the aforementioned lvconvert again.

Add tests to check conversion to striped/raid* gets rejected.
Enhance a test comment.

a37bb7b2a5 dmeventd: adjust mirror/raid DSOs to new repair design

e5b6f2685a dmeventd: reintroduce fix mirror DSO to work with lvmetad
Commit 07ded8059c assumed that the mirror is blocked which is not the case.

It is accessible, degraded and in need of repair because some of its legs
(partially) failed.  Any auto-repair via dmeventd fails though because
of lvmetad not providing proper data about the failed PV(s).  That's why
this workaround got introduced in commit 76f6951c3e until we get to
the lvmetad interaction core issue.

Mind any mirror auto-repair failure is caused by such lvmetad interaction
problems not yet solved so disabling lvmetad works as a resort as elaborated
on in the related bz.

Reintroducing the interim solution.
