Currently it's been checked for 'zero' header for thin-pool,
but lets use it always for cache as well - since it's relatively 'cheap'
detection of read 'error' problems as thin/cache tools
currently do not work fast enough in this case.
export LVMDBUSD_SESSION=True to run on the session bus instead
of the system bus so that we can run the unit test without
installing the dbus conf file.

Reduced the size of LVs created and use actual PE numbers instead of hard
coding them to allow us to work with the loop back devices.

It appears that the output of lvconvert --merge can vary some. The code
was blowing up as it was trying to parse a line of stdout to retrieve the
% complete, but the line did not have the needed format and an execption
was thrown. The uncaught exception caused the background thread to exit
without updating the job object, which caused the client to hang forever
waiting. Added a default exception handler to prevent unhandled execptions
causing hangs and removed the parameter skip_first_line as it's no longer
needed. The code checks to see if the line can be parsed before doing so.

After the lockspace has been successfully removed,
invalidate the name field in the lockspace struct.
The struct remains on the list of lockspaces until
the struct can be freed later. Until the struct is
freed, its name will prevent another new lockspace
from being created with the same name.
When update fails in suspend() (sending of messages
fails because metadata space is full) call resume(),
so the locking sequence works properly for clustering.
Also failing deactivation should unlock memory.
Fix reporting of Fail thin-pool target status
as attr[8] letter 'F'.
Report 'needs_check' status from thin-pool target via
attr field [4] (letter 'c'/'C'), and also via CheckNeeded field.
TODO: think about better name here?
TODO: lots of prop_not_implemented_set
Fix parsing of 'Fail' status (using capital letter) for thin-pool.
Add also parsing of 'Error' state for thin-pool.
Add needs_check test for thin-pool.
Detect Fail state for thin.
Ask for confirmation when using pvcreate/pvremove on a PV which is
marked as belonging to a VG, just like we do in case of a PV which
belongs to known VG:
$ pvcreate -ff /dev/sda
Really INITIALIZE physical volume "/dev/sda" that is marked as belonging to a VG [y/n]? n
/dev/sda: physical volume not initialized
$ pvremove -ff /dev/sda
Really WIPE LABELS from physical volume "/dev/sda" that is marked as belonging to a VG [y/n]? n
/dev/sda: physical volume label not removed
The host that owns foreign VGs is responsible for fixing up PV_EXT_USED
flag - the same already applies to repairing any inconsistent VG.
This patch also moves the iteration over vg->pvs inside
_check_or_repair_pv_ext fn - it's cleaner this way.
pv->vg is not set yet during pvcreate processing. Use pv->fmt instead to
check for these fake PVs (all normal PVs have format defined, devices
which are not PVs don't have this set).
This fixes commit 0000db7f98.
If we know that a PV belongs to some VG and we're missing metadata
(because we have only those PV(s) from VG present in the system that
don't have metadata areas), we should skip such PV when processing
under system ID.
This is because we know that the PV belongs to some VG, but we
really can't decide whether it matches system ID unless the VG
metadata is present again.
Some of the PVs are not even orphan PVs - they're fake PVs - this can
happen if we're listing all devices with "pvs -a". Such PV must not
be marked as used.
