08888d57cb tests: check for supported dBus interface
Instead of blindly relying on sleeping, that dBus understands our
dBus interface, query the info with dbus-send.

f524dd80f4 tests: query dmeventd instead of sleep
Checking status of running instance of dmeventd should be a better 'sleep'.

092951f634 dmeventd: check for running dmeventd for status
Before initiation fifo communication, check whether there is
running dmeventd - in case there is no running instance, this
would be just blocked for 5 seconds trying to open fifo.

6ec84993bd makefiles: avoid using # with awk
Also awk got annoyed by this \# char sequence which is reported
as incorrect, however older rpm builder were failing without this.
So let's just try other variant.

d6df31fba1 pools: no checking for lv/vgremove deactivation
Thin-pool and cache-pool targets got already quite stable so let's try
to remove checking of pools when using lvremove or vgremove commands.

This skips checking pools when they are going to be removed, but it
also when removing thin volume that was the only user of a thin-pool.
In this case thin-pool will be still there and could be activated
again with another thin volume and thin_check will be executed
in this moment. In this case it can delay discovery of metadata damage.

2fdf3b137a thin-pool: avoid reactivation on new thin-pool
Shortens processing of 'lvcreate -L -V -T' command and
avoid deactivation and its activation with thin_check of the empty
created thin-pool that will be used for the new thin volume
made with a single lvcreate command.

dda859027c vdo: use stats msg parser for also segment status
Shuffle code to parsing VDO message also for lvs segment status
so it can report correctly data usage for VDO LVs.

For this change move code and also change its API to use just mempool.

Fixes usage with upstream 6.9 vdo target driver.

203c8b3997 vdo: fix status message parsing
When using message API for parsing VDO stats info, 0 was wrongly
used for fallback for trying the old sysfs API.

Switch to use  ULLONG_MAX for values that could not have been obtained
through the message call.

Fixes lvdisplay info for freshly created VDO volume with 0 used data
blocks.

50b188eebd dev_manager: improve readability
Make a seperate function to decode which ID should be user
for cvol meta or data volume - also avoids duplication of code.
As a result it's now also easier to see how the lvid is build.

5dec664ccf lvmlocks: rework dm_strncpy
Fix cutting away 1 character via incorrect usage of dm_strncpy
introduced in last batch of commits and use sizeof(buffer) to
get proper sizes.

In case of use strcpy_name_len() the replacement was invalid,
so we need to restore this case since sanlock uses buffer without
nul ending, so we would strip one more character from the buffer.

Also start to use dm_strncpy() without (void) for unchecked usage.

fef49a0e86 cov: remove unnecessary sanity check
This sanity check actually confused in some way Coverity
giving it some assumption about array access.

Since these two checks basically validated compiler's capability
to add and then substract the number from char pointer we likely
don't really need them - as if this base math would not work,
compiler would be having far more troubles...

So drop them - and get rid of report:
