a198224666 dev-cache: skip scanning known blockless dirs
Skip scan and stat() for dirs and nodes within known /dev/ paths,
where no block devices are located.

Also strlen(_cache.dev_dir) just once.

TODO: add more dirs to _no_scan (configurable via lvm.conf ?)

93918a1990 cleanup: use ARG_LONG_OPT
Just like with _VAL strings, also _ARG strings do not need to
be present - as we can easily check for LONG opt version just
by adding attribute.

With attribute ARG_LONG_OPT string arg name[] becomes unused
and can be safely removed.

Also within _find_command_id_function() we do not need to handle
'command_enum == CMD_NONE' as separate case and just use single loop.

73298635b9 lvm: fix shell completion
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.

47f8bda051 lvremove: remove device_id for PVs on LVs
When PVs are created on LVs, remove the devices file entries
for the PVs when the LVs are removed.  In general, the devices
file entries should be removed with lvmdevices --deldev when
the LVs are removed (lvremove is the equivalent of detaching
a device from the system when layering PVs on LVs.)
This change is effectively an automatic lvmdevices --deldev
command that is built into lvremove when the LV has a PV on it.

c609dedc2f Allow system.devices to be automatically created on first boot
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.

c2c028c680 tests: reduce number of created LVs
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.
