8cbba1d164 lvmlockd: enable vdo conversion
As we turn 'already' active/locked LV into a data LV of vdopool,
we just keep active lock for such volume (uuid is preserved).

75b28ab49d lvmlockd: query the simplest check first
Check for visibility of the LV first.

TODO:

Short check list and test only for those that can't be locked,
but they are visible LVs.

f24eb81dbe tests: improve LD_LIBRARY_PATH setting
Some linkers do need libdevmapper-event-lvm2.so.2.03,
so add also this symlink to the tests  /lib dir.
This fixes the need to use previous LD_LIBRARY_PATH complex
setting and now works with much shorter list.

cb2d32bdc4 debug: fix sscanf type
Last commit c38b668fc3 was pushed
with type 'scanf' instead of 'sscanf' needed for buffer reading.
Interestingly this caused scanning from 'stdin' descriptor and
thus failures in lvm shell usage.

c38b668fc3 debug: fix parsing of /proc/self/stat
The code in init_log_file relies on the process name (COMM) to not
contain whitespaces. This change fixes it by looking up the right-most
parenthesis to safely jump past COMM.

For more context see:
https://www.openwall.com/lists/oss-security/2022/12/21/6

Code is only used with testing, so it should have no impact on regular
users.

00b5d7b037 lv: followup seg_monitor reporting
With 3596558861 it's been introduced
a more fine grained description.
However 'disabled' might be actually more confusing then empty field,
so keep only the info about 'not enabled'aka dmevend is not allowed
to monitor LV which otherwise could be monitored.

39457234db lvconvert: support conversion to thin volume
Update pool conversion function to handle also conversion of
thick LV to thin LV by moving thick LV into thin pool data LV
and creating fully provissioned thin LV on top of this volume.

Reworking existing conversion to use insert_layer_for_lv co
the uuid is now kept with thin-pool - this should however not
really matter as we are doing full deactivation & activation cycle.

With conversion to thin LV user can use same set of arguments
to set chunk-size.

TODO: add some smart code to decide best values for chunks sizes.

88f1e7a9a7 cache: support more segtypes for caching
Enable support to cache thin/error/zero virtual targets.

Use can now select whether he want to cache whole thin-pool,
or an individual thin volume out of whole thin-pool.
Support using zero and error LVs as data volume for
cachepool is possibly useful for benchmarking, not much
can be expected from such setup.
