be9a64e654 device_id: make dmeventd use system.devices by default

e6c6713a1b hints: correct fix for hints with device ids
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.

63b469c160 device_id: fix hints with device ids
Fix some interactions between device IDs and hints.  Hints
may limit the scanned devices which should not always trigger
a search for the PVs that were intentionally not scanned.
Hints should also be invalidated if they contain a device
that's become excluded by an internal filter such as the
device_id filter.

1901a47df1 device_id: fix conditions for device_ids_refresh
Fix commit 847f1dd99c
"device_id: rewrite validation of devname entries"

which began calling device_ids_refresh() in cases where it
was unnecessary, leading to extra PV searches and warnings.
Specifically, a command like "lvs <vg>" would use the hints
file to scan only devices for the named VG.  This means that
scanning other PVs would be skipped, and device IDs of those
PVs could not be validated because there are no PVID values
to verify.  This missing info would cause messages about
the missing info, and would cause device_ids_refresh to
search for the PVs that had been intentionally skipped.

88aa285a79 devices: refresh device ids if the system changes
If the system changes, locate PVs that appear on different devices,
and update the device IDs in the devices file.  A system change is
detected by saving the DMI product_uuid or hostname in the devices
file, and comparing it to the current system value.  If a root PV
is restored or copied to a new system with different devices, then
the product_uuid or hostname should change, and trigger lvm to
locate PVIDs from system.devices on new devices.

report: support printing full column names in report headings
Reuse existing report/headings config setting to make it possible to
change the type of headings to display:
  0 - no headings
  1 - column name abbreviations (default and original functionality)
  2 - full column names (column names are equal to exact names that
      -o|--options also accepts to set report output)

Also, add '--headings none|abbrev|full|0|1|2' command line option
so we are able to select the heading type for each LVM reporting
command directly.

8698f9dce6 pool: use predefined name for metadata LV
While create new LV for pool volume, use name from 'pool_metadata%d' naming
sequence. This LV is later on renamed to  pool_t/cmeta, but if there
is any error in the middle, we may evenutally leave some 'volume',
With this name it can be slightly more obvious how it got there,
but also when we handle _pmspare name - we get slightly more predictible
name used there for it.

However for a standard usage this commit shall no visible impact as the
name is used temporarily just for cleaning LV.

In previous lvm versions, trailing spaces at the end of a t10 wwid would

would look something like "t10.123_".  Current versions of lvm ignore
trailing spaces in a t10 wwid, so the IDNAME string used would be
"t10.123".  The different values would cause lvm to not recognize a
device in system.devices with the trailing _.  Fix this by ignoring

raid+integrity LV to fail prematurely when checking stripe parameters.
An unhelpful error message about stripe size would be printed.

6d262eaf64 lvmcache: fix valgrind error when dropping md duplicate
When lvmcache info is dropped because it's an md component,
then the lvmcache vginfo can also be dropped, but the list
iterator was still using the list head in vginfo, so break
from the loop earlier to avoid it.

8947964f10 wipe_lv: use zeroing ioctl only for large sizes
There is no easy way to detect, whether device supports zeroing,
and kernel also zeroes device when it's not directly supported,
but with extra message:

operation not supported error, dev X, sector Y op 0x9:(WRITE_ZEROES)...

So to avoid generating such message with every 'lvcreate', use for
zeroing of upto 8K just standard write of zeroed page.
(maybe we can go with even larger sizes).

31cfcf7ce9 fix dev_name use in add_areas_line
This function was relying on dev_name() returning NULL
to indicate no device, but dev_name never returns NULL.

Creating a snapshot of a cache LV with a cachevol would fail
because cache_check was not being skipped.

e8e6347ba3 vdo: use fixed size vdopool wrapper
Instead of using size of 'empty header' in vdopool use fixed size 4K
for a 'wrappeing' vdo-pool device.

This fixes the issue when user tried to activate vdo-pool after
a conversion from vdo managed device with 'vgchange -ay' - where
this command activated all LVs with 'vdo-pool' wrapping device as well,
but this converted pool uses  0-length header.

This 4k size should usually prevent other tools like 'blkid' recognize
such device as anything - so it shouldn't cause any problems with
duplicate indentification of devices.
