Device quirks may cause sysfs wwid file to change what it
displays, from a bogus eui... string to an nvme... string.
The old wwid may be saved in system.devices, so recognizing
the device requires finding the old value from libnvme.
After matching the old bogus value using libnvme, system.devices
is updated with the current sysfs wwid value.

In case of different PV sizes in a VG, the lvm2 allocator falls short
to define extended segments resiliently asked for 100%FREE RaidLV extension
and a RAID distinct allocation check fails. Fix is to release a memory pool
on the resulting error path.
Until the lvm2 allocator gets enhanced (WIP) to do such complex (and other)
allocations proper, a workaround is to extend a RaidLV to any free space on
its already allocated PVs by defining those PVs on the lvextend command line
then iteratively run further such lvextend commands to extend it to its
final intended size. Mind, this may be a non-trivial extension interation.

vgchange --locktype sanlock|dlm --lockopt force <vgname>
can be used to change the lock type without lvmlockd or
the lock manager involved.
(cherry picked from commit 4dc009c872)
Previously, a command would call lockd_vg() for a local VG,
which would go to lvmlockd, which would send back ENOLS,
and the command would not care when it saw the VG was local.
The pointless back-and-forth to lvmlockd for local VGs can
be avoided by checking the VG lock_type in lvmcache (which
label_scan now saves there; this wasn't the case back when
the original lockd_vg logic was added.) If the lock_type
saved during label_scan indicates a local VG, then the
lockd_vg step is skipped.

Fix commit b65a2c3f3a "vgimportdevices: skip lvmlockd locking"
which intended to disable lvmlockd locking, but the lockd_gl_disable
flag was mistakenly set after lock_global() so it wasn't effective.
This caused vgimportdevices to fail unless locking was started.

Previous commit 82617852a4
introduce bug in complession - as the rl_completion_matches()
needs to always advance to next element where the index
is held in static variable.
Add comment about this usage.

An OS installer can create system.devices for the system and
disks, but an OS image cannot create the system-specific
system.devices. The OS image can instead configure the
image so that lvm will create system.devices on first boot.
Image preparation steps to enable auto creation of system.devices:
- create empty file /etc/lvm/devices/auto-import-rootvg
- remove any existing /etc/lvm/devices/system.devices
- enable lvm-devices-import.path
- enable lvm-devices-import.service
On first boot of the prepared image:
- udev triggers vgchange -aay --autoactivation event <rootvg>
- vgchange activates LVs in the root VG
- vgchange finds the file /etc/lvm/devices/auto-import-rootvg,
and no /etc/lvm/devices/system.devices, so it creates
/run/lvm/lvm-devices-import
- lvm-devices-import.path is run when /run/lvm/lvm-devices-import
appears, and triggers lvm-devices-import.service
- lvm-devices-import.service runs vgimportdevices --rootvg --auto
- vgimportdevices finds /etc/lvm/devices/auto-import-rootvg,
and no system.devices, so it creates system.devices containing
PVs in the root VG, and removes /etc/lvm/devices/auto-import-rootvg
and /run/lvm/lvm-devices-import
Run directly, vgimportdevices --rootvg (without --auto), will create
a new system.devices for the root VG, or will add devices for the
root VG to an existing system.devices.

lvm2 for a while already optimizes 'vgremove' operation to
a single commit when possible if all LVs can be
easily deactivated.
So the number of LVs doesn't matter much - but the tested
case 'test_delete_non_complete_job' seems to be taking
some time anyway to capture the exception.
So just reducing the running time of the test significatanly
as we don't need to create 64LVs for 4 'execution mode' runs.
Order is used for man page generation (although not completely).
So place 'zero & error' to the end of list.
Keep linear,striped,snapshot in front.
For the rest use alphabetic order.
