b1e21cf9ed raid: fix write_commit_backup
With commit 41c10034aa we actually
do require LV to be used with _vg_write_lv_suspend_commit_backup().

So write a proper separte single wrapper for write && commit && backup.

4e4067dd94 libdm: fix initialization of head for reused structure
Dmeventd reuses  'dm_task' struct for some STATUS operation, but due to
missing reinitization of dm_task target list, it has caused misprocesing
of recieved events as the parsed target has been simply added to the
list of existing status and cause multiple actions being called for
single event.

c465ca6a3a raid: allow more sync action for extraction
Since we discovered status reporting from 'md' goes from large set
of weird states we can't just decided based on this word.
So let it pass for rebuild and idle as well
and check for health devices afterwards.

2ef8da61eb libdm: implement dm_percent_to_round_float
Add function to adjust printing of percent values in better way.
Rounding here is going along following rules:

0% & 100% are always clearly reported with  .0 decimal points.

Values slightly above 0% we make sure a nearest bigger
non zero value with given precission is printed
(i.e. 0.01  for  %.2f  will be shown)

For values closely approaching 100% we again detect and adjust value
that is less then 100 when printed.
(i.e. 99.99  for %.2f will be shown).

For other values we are leaving them with standard rounding mechanism
since we care mainly about corner values 0 & 100 which need to be
printed precisely.

0016b79c8b dmeventd: improve more raid status reporting

since otherwice 'Aa idle' is normally visible.

plugin detects raid is in sync.

653bdedb83 raid: plugin does not to use --config
Functionality of ignore suspend devices is already granted by:

lvm2_disable_dmeventd_monitoring() -> init_run_by_dmeventd() ->
init_ignore_suspended_devices().

In fact plugins should never use --config because it has
some unpleasant technical issues.

1bdcd156fd cache: restore origin only reload
Basically reverting commit 58a9f88b8c.
We can use origin_only  in case we are snapshot's origin,
as we do support this stack.

So when we are 'uncaching'  origin+snaps - we do need to reload only
origin and we do not need to play with snaps.

6d30350dd1 raid: improving messages for regionsize change
Handle change of 'region size' better and follow also standard rule
if the command can't success (i.e. size is already same) we return
error for all such cases.

Also log_pring more info about adjusted value (just like we
do for rounding)

Also avoid keep pointers on 'display_*' values - they are in
ringbuffer for immediate use - not to be kept across multiple calls
(as they could be already overwritten by later calls) - so dropped

732928dda8 cache: fix lvdisplay --maps
'lvdisplay -m' tried to go through NULL policy settings,
when such policy was not defined for CachedLV.

Patch is fixing display of cache-pool without defined settings,
as this is now a valid pool and we mostly want users to define
these settings when actually really caching a LV.

58a9f88b8c cache: drop usage of origin_only
Since cache LV can be a stacked device, there is no real reason
trying to use slight optimised tree for origin_only cache reload
(it could be even wrongly implemented in this case).

We can easily go with stardard tree load here.

ca9e6cec61 cache: make syncing abortable by user
When user runs command like 'lvconvert --splitcache' the operation
might be actually either slow or not making any progress in kernel,
so lets give user a chance to abort such operation.

When user press 'Ctrl+C' device table is restored to pre-flushing state.
