2d64ffaee5 hash: use individual hint sizes
Use different 'hint' size for dm_hash_create() call - so
when debug info about hash is printed we can recognize which
hash was in use.

This patch doesn't change actual used size since that is always
rounded to be power of 2 and >=16 - so as such is only a
help to developer.

We could eventually use 'name' arg, but since this would have changed
API and this patchset will be routed to libdm & stable - we will
just use this small trick.

78c7ae7cd2 lvremove: reduce ioctl count
Just like with deactivation, call of 'lv_is_not_in_use()'
now has embeded report for inactivate LV.

Note: this patch cannot be backported to stable-2.02 - as
there lv_is_active() has 'cluster' meaning and differs from lvinfo().

dceef4709d deactivation: reduce ioctl count
When LV is deactivativate, we check for presence, and later
for some LV types also for being in use.

We can however do this check in 1 step for them a remove extra ioctl.

Add return value '2' to lv_check_not_in_use() to recognize LV is not
present.

Existing users were just testing for 0, so no change for them.

936c7b5104 vg_read: reuse already parsed config tree
When parsing VG metadata we can create from a single config tree
also 'vg_committed' that is always created for writable VG.

This avoids extra uncessary step of serializing and deserilizing
just parsed VG.

bc0cb66304 vg_write: optimize caching of precommitted VG
Every vg_write stores new 'metadata' into precommitted slot.
For this step we use 'serialized buffer' to ascii metadata.

Instead of recreating this buffer after whole 'vg_write()' we
use this buffer instantly for creating of precommitted VG.

This has also the advantage of catching any problems with
reparsing of ascii metadata back to VG early before any write.

a125a3bb50 lv_remove: reduce commits for removed LVs
This patch postpones update of lvm metadata for each removed
LV for later moment depending on LV type.

It also queues messages to be printed after such write & commit.

As such there is some change in the behavior - although before
prompt we do make  write&commit happens automatically in some
other error case we rather keep 'existing' state - so there
could be difference in amount of removed & commited LVs.

IMHO introduce logic is slightly better and more save.

But some cases still need the early commit - i.e. thin-removal
and fixing this needs some more thinking.

TODO: improve removal at least with the case of the whole thin-pool.
i.e. we can simply recognize removal of 'all LVs/whole VG'.

f5fbb1b76f lvmlockctl: replace popen and system

e9d10f3711 filters: better message for excluding LV
Make the generic "device is not usable" message from filter-usable

2a9a3346e7 archive: support interruption
When lvm2 calls archive() or backup() it can be useful to allow handling
break signal so the command can be interrupted at some consistent point.

Signal is accepted during processing these calls - and can be evaluated
later during even lengthy processing loops.

So now user can interrupt lengthy lvremove().

eb1160ee42 lvremove: backup at the end of loop
Taking backup with each removed LV is slowing down the process
considerable and is largerly uneeded. We are supposed to take
backup only on significant points and making sure the backup
is correct when the command is finished.

TODO: check how many other commands can be improved.
