631b8edefb device_id: ensure pvid buffers are ID_LEN+1
A pvid string read from system.devices could be less
then ID_LEN since system.devices fields can be edited.
Ensure the pvid buffer is ID_LEN+1 even if the string
read from the file is shorter.

de2b11f39a device_id: improve searched_devnames temp file
Include info in the temp file to confirm that it should be used.
The temp file is meant to suppress repeated, identical searches
for the same PVIDs on the same set of devices.  Write to the file
a count and hash of the missing PVIDs and a count and hash of the
devices to search.  A subsequent command will ignore and remove
the temp file if any of these values differ.  We don't want to
suppress a search if a change has occured, and a missing PV could
be found by scanning devices.

35cefa50fa device_id: change default search_for_devnames to all
Problematic scenario:
. the device for a PV has no wwid, so it's identified in system.devices
  with IDTYPE=devname IDNAME=/dev/foo
. user adds/enables a wwid for the device
. on reboot, the device name changes, e.g. now /dev/bar
. the code that searches for the new device name includes an
  optimization to skip looking on devs that have a wwid, on
  the basis that a device with a wwid won't have IDTYPE=devname
. this optimization causes lvm to not look for the PV on /dev/bar
  since that device now has a wwid, so the PV is not found
. the optimization is enabled by search_for_devnames="auto"
. change the default to search_for_devnames="all" which does not
  use the problematic optimization

37773c1055 lvmdevices: new output and options for check and update
- add new comparison between old and new entries, and use this
  as the basis for new dedicated output for check and update
- add new --refresh option to search for missing PVIDs on all
  devices, and possibly update the device ID
- internally, only use the term "refresh" for cases where a
  new device ID may be found and assigned for a missing PVID

3fa424f893 tests: lvmdbusd handles empty LvCommon.Devices
During vdo testing with smaller block devices the test needs to determine
which PVs in a VG are unused.  This was leveraging LvCommon.Devices, but
that isn't populated when a LV is resides on a LV pool instead of a PV.
This is a known limitation of the code at this time.  For now we will walk
all the PVs in the VG looking for ones that don't have any associated LVs
and use them instead.

3f084b06e9 device_mapper: raid status handle all a chars
When getting raid status from some older kernels, we may get an 'a'
for 'A' leg when doing initial synchronization.
This may prohibit removal of newly synchronized leg until synchronization
is finished.
So in this case change the status to look like being reported
from a newer kernel version.

9ff0615546 device_id: first match non-devname device ids
Incorrectly matching a dev to a devname id (due to changing devnames)
before matching the dev to a proper device id, can result in the
dev not being matched to the real id.

libdm: report: fix invalid JSON if using DM_REPORT_OUTPUT_MULTIPLE_TIMES and selection
When reporting in JSON format, we need to be able to find the 'last
displayed row', not just 'last row' as we did before. This is used
to decide whether to put the JSON_SEPARATOR (the ',' character)
between the lines when reporting in JSON format.

This is mainly important in case we use a combination of JSON format
and a report marked with DM_REPORT_OUTPUT_MULTIPLE_TIMES flag.
Such report may be reused several times with different selection
criteria each time. In that case, the report always contains all lines
in memory, even though some of them do not need to pass the selection
criteria that are currently used.

Without DM_REPORT_OUTPUT_MULTIPLE_TIMES flag, the report only contains
the lines that have passed the selection criteria, so the this wasn't
an issue in this case.

Fix suggested by Lars Ellenberg and reported here: https://github.com/lvmteam/lvm2/issues/130

c7851b9c34 tests: longer delay between table reloads
It looks like there is some kernel bug/limitation
that may cause invalid table load processing:

dmsetup load LVMTEST-LV1
device-mapper: reload ioctl on LVMTEST-LV1  failed: Invalid argument
  md/raid:mdX: reshape_position too early for auto-recovery - aborting.
           md: pers->run() failed ...
device-mapper: table: 253:38: raid: Failed to run raid array (-EINVAL)
device-mapper: ioctl: error adding target to table

However ATM there is not much we can do then make delays bigger.

is out-of-sync while other leg is in-sync.

Hot fix allows to proceed with such down conversion.

Fixes commit 63b469c160
"device_id: fix hints with device ids"

It's not correct for internal filtering to be a factor
in validating the set of devs that are the basis for hints.

Instead, look for inconsistencies between a hint entry and
the corresponding devices file entry.

9668d40d5a resize: reduce without prompt for no-fs case
Apply the same logic for 'lvreduce' which exists for newer
systems (compiled with HAVE_BLKID_SUBLKS_FSINFO)
also for older systems for one very common practical case where
the active LV does not have any blkid known signature/filesystem.

New variant recognized this situation and allowed to proceed
without requesting a prompt, while the older variant always
requested confirmation prompt.

With this patch command now works equily for both variants
for 'active LV' without signature and allows to reduce LV
without prompting.
