12eb284eec tests: fix name-mangling test
We need to use "--verifyudev" for dmsetup mangle command used in
the name-mangling test since without the --verifyudev, we'd end up
with the failed rename.

Also, add direct check for the dev nodes - node with old name must
be gone and node with new name must be present. Before, we checked
just the output of the command.

One bug popped up here when renaming with udev and libdevmapper
fallback checking the udev when target mangle mode is "none"
(fixme added in the libdevmapper's node rename code).

ca880a4f13 autoactivation: issue a VG refresh before autoactivation only if 'change' lvmetad flag is set
This prevents numerous VG refreshes on each "pvscan --cache -aay" call
if the VG is found complete. We need to issue the refresh only if the PV:
  - is new
  - was gone before and now it reappears (device "unplug/plug back" scenario)
  - the metadata has changed

c0f1eb5f0f dev_manager: check prohibited devices earlier
Reorder detection for internal device - since this test
is much simpler then target analysis, check it sooner.

Replace test for '68' with sizeof & ID_LEN

Add FIXME about device alias problem with is_reserved_lvname,
since this test fails on devices like /dev/dm-X
so we need to convert tests to UUID.

bf42119b22 config: accept empty values for global/thin_disabled_features
Let's do this the other way round - this makes more logic than commit b995f06.
So let's allow empty values for global/thin_disabled_features where
such an empty value now means "none of this features are disabled".

b995f06abf config: mark global/thin_disabled_features as having no default value
The global/thin_disabled_features should be marked as having no default
value. Otherwise the output from 'lvm dumpconfig --type default' would
have 'thin_disabled_features=""' which will produce an error message
'Ignoring empty string in config file ...' if such output is feed
back to lvm.

4cc5c689b8 thin: add pool uuid suffix for pool volume
Even though we make pool volume as a public visible LV,
we still do not want tools to look at this volume.

While we do not create /dev/vg/lv link, device is still
accessible via /dev/mapper/vg-lv and there is no easy
way to recognize it's private without lvm2 metadata.

Enhance UUID with -pool suffix and directly skip
any LV with a suffix in  device_is_usable() call.

TODO: enhance other targets with this logic.
blkid may probably use same simple logic.

8a60cbcf45 thin: always activate and deactive pool when creating

4d64e91efd thin: do not check of empty pool with messages
The empty pool is also the pool which has yet queued list of messages
and transaction_id == 1.

Problem is exposed when pool is created inactive.

1850a6e454 thin: fix pool_has_message return for NULL params
When pool_has_message() is queried with NULL lv and 0 device_id
it should just return 'true' when there is any message queued.
So it needs to return negative value dm_list_empty().

Since there is no user for this code path in code currently,
this bug has not been triggered.

7a6c0e2425 dmeventd: wakeup timeout thread earlier

wakeup sleeping condition, so the thread is deleted earlier.
So the thread resource is release earlier.

2a9b62c7f9 dmeventd: remember number of log disablings
Individual events are handled through separate threads,
so once we have more then a single thread in this eventwait
sleeping, we got race on the dm_log setting, since
if one event is timeout out on alarm, while another is still waiting,
then dm log has been restored to NULL and the next sigalarm
has been reported as error.

Fix it by introducing counter which is protected via mutex,
and only when the last event is released, logging is restored.

TODO: libdm seems to have some static vars which may audit
for this type of use.

eeff7729d9 config: use small local static buffer instead of mempool for temporary config path
We can't use mempool for temporary variable for configuration path inside
find_config_tree_* functions since these functions can use the mempool
themselves deeper in the code and we can free mempool chunks only from
top to bottom which is not the case here (some default string
configuration values can be allocated from the mempool).
