5467a3b2b7 filters: update composable filter
Last commit made dump filter only partially composable.
Add remaining functionality and also support composable wipe,
which is needed, when i.e. vgscan needs to remove cache.

(in release fix)

7c89cbf03a tests: run all the test flavours in a single batch
This means that a test failure in one flavour no longer prevents all the
subsequent flavours from running. We also get an aggregate summary at
the end of the entire batch, instead of summaries interspersed with
progress output. Do not fail when flavour overrides are empty

e7878da921 filters: toplevel filter not persistent
Add a generic dump operation to filters and make the composite filter call
through to its components. Previously, when global filter was set, the code
would treat the toplevel composite filter's private area as if it belonged a
persistent filter, trying to write nonsense into a non-sensical file.
Also deal with NULL cmd->filter gracefully.

05bf4b8cc3 vgimportclone: override global_filter in lvm.conf
The global filter in system's lvm.conf may conflict with the custom filter we
set up in vgimportclone (they can easily fail to intersect). Since we explicitly
avoid talking to lvmetad in vgimportclone, it is safe and reasonable to do so.

e5baaf4ac9 lvcreate: update thin validation

562c678ee2 DM RAID: Add ability to throttle sync operations for RAID LVs.
This patch adds the ability to set the minimum and maximum I/O rate for
sync operations in RAID LVs.  The options are available for 'lvcreate' and
'lvchange' and are as follows:
  --minrecoveryrate <Rate> [bBsSkKmMgG]
  --maxrecoveryrate <Rate> [bBsSkKmMgG]
The rate is specified in size/sec/device.  If a suffix is not given,
kiB/sec/device is assumed.  Setting the rate to 0 removes the preference.

e4dfa785d1 libdm: compensate suspend counter for live table
This patch may not be fully correct. It tries to solve
the imbalanced suspend counter.

The problem starts when some LV is created and fails in resume path.
(i.e. resuming to large PV (enforced) over small loop devices)

This fails in _resume_node() after dm_task_run(). And while
existing device with empty table is left in inactive table,
further calls are reporting this device is in suspend state.

When later the lvm2 tries to rollback created device and deactivate it,
it will end with internal error, when we try to decrement
never incremented suspend counter.

As an 'easy fix' for now update suspend counter only for live nodes.

TODO: explore better fix.

59962d8d3e snapshot: require 3 chunks for creation
There is no point in creation of 2chunks snapshot,
since the snapshot is invalidated immeditelly with the first write
as there is no free chunk for COW blocks
(2 chunks are used by the snap header and the 1st. metadata chunk).

Enhance error message about the lowest usable size.

e992cb253c dmeventd: use dm_get_status_snapshot()
Switch to use libdm dm_get_status_snapshot() function for
reading status info.
This fixes bug, where the code was using 32bit integers,
while the snapshot target is able to return 64bit sizes.
However this also means, someone is using >1TB snapshot
cow devices, which is actually very bad idea anyway, since the
perfomance and memory usage in this case is very bad.

cb587fd100 libdm: free mem pool on err path
Since we use get_status also in dmeventd, which may use one pool
for a single device, in case it would be repeatedly returning error,
it may not be freeing the pool and would cause slow but steady growth.
To stay safe in the error path release any allocated memory.
