Scenario: Given an existed LV `lvol0`, I want to create another LV
on the PVs used by `lvol0`.
I use `build_parallel_areas_from_lv()` to obtain the `pv_list` of each segments.
However, the returned `pv_list` is not properly initialized, which causes
segfault in subsequent operations.

When converting from striped/raid0/raid0_meta
to raid6 with > 2 stripes, allow possible
direct conversion (to raid6_n_6).
In case of 2 stripes, first convert to raid5_n to restripe
to at least 3 data stripes (the raid6 minimum in lvm2) in
a second conversion before finally converting to raid6_n_6.
As before, raid6_n_6 then can be converted
to any other raid6 layout.
Enhance lvconvert-raid-takeover.sh to test the
2 stripes conversions to raid6.

We need to have Ceph RBD devices mapped first before use in a stack
where LVM is on top so make sure rbdmap.service is called before
generated lvm2-activation-net.service.
On shutdown, we need to stop blk-availability first before we stop the
rbdmap.service.

This is the number of concurrent async io requests that
the scan layer will submit to the bcache layer. There
will be an open fd for each of these, so it is best to
keep this well below the default limit for max open files
(1024), otherwise lvm may get EMFILE from open(2) when
there are around 1024 devices to scan on the system.
"lvconvert --type linear RaidLV" on striped and raid4/5/6/10
have to provide the convenient interim layouts. Fix involves
a cleanup to the convenience type function.
As a result of testing, add missing sync waits to
lvconvert-raid-reshape-linear_to_raid6-single-type.sh.

With improved mirror activation code --splitmirror issue poppedup
since there was missing proper preload code and deactivation

Prohibit, because the tracking can't continue and
further conversions may fail with bogus error messages.

Amound of linked libraries grows.
Most of them we don't need to lock in, since we are not using
them in locked section, so skip locking them in memory.
When pvmoving LV - the target for LV is a mirror so the validation
that checked the type is matching was incorrect.
While we need a more generic enhancment of LVS output for pvmoved LVs,
for now at least stop showing internal errors and 'X' symbols in attrs.
The previous method for forcibly changing a clustered VG to
a local VG involved using -cn and --config locking_type=0.
Add an alternative that is consistent with other forced
lock type changes:
vgchange --locktype none --lockopt force.
In case "lvconvert -mN RaidLV" was used on a degraded
raid1 LV, success was returned instead of an error.
Provide message to inform about the need to repair first
before changing number of mirrors and exit with error.
Add new lvconvert-m-raid1-degraded.sh test.
