toollib: fix segfault if using -S|--select with log/report_command_log=1 setting
When we are using -S|--select for non-reporting tools while using command log
reporting (log/report_command_log=1 setting), we need to create an internal
processing handle to handle the selection itself. In this case, the internal
processing handle to execute the selection (to process the -S|--select) has
a parent handle (that is processing the actual non-reporting command).

When this parent handle exists, we can't destroy the command log report
in destroy_processing_handle as there's still the parent processing to
finish. The parent processing may still generate logs which need to be
reported in the command log report. If the command log report was
destroyed prematurely together with destroying the internal processing
handle for -S|--select, then any subsequent log request from processing
the actual command (and hence an attermpt to access the command log report)
ended up with a segfault.

25cb6a042f vgimport: invalidate hints
There may be some unconventional methods of sharing disks with vgimport
where hints could cause confusion.  Hints should be disabled when
sharing disks, or pvscan --cache used to regenerate hints as needed,
but invalidating hints from vgimport might help reduce confusion.

08265641f3 pvscan: remove warning about excluded root dev
This was trying to warn about a misconfig where the root PV
was excluded by the devices file, but it wasn't covering all
cases.  Also, it's not very useful because the root LV is
usually activated directly in the initrd.

a0437225aa makefiles: avoid piping
Addressing problem for user of system without default bash shell.

As reported "set -o pipefail" is a bashism that causes the build to
fail when /bin/sh does not point to bash.
For example, this has been observed causing build failures
on Gentoo when /bin/sh is symlinked to /bin/dash.

Rule has been reworked and we started to use .DELETE_ON_ERROR to
ensure that with any errors during file generation, such invalid
file is automatically removed.

Rules were reworked to avoid using pipe and instead use temporary
files when necessary.
Printing lines with echo was replaced with POSIX recomended 'printf'
as proposed by reporter since handling of escape characters and
the "-n" flag for "echo" aren't portable across shells.

Also some build deps has been added.

1fb5107eea lvresize: better detection of BLKID_SUBLKS_FSINFO
Use configure detection instead of trying to directly include
blkid.h inside lvresize.c - where we do not pass in BLKID_CFLAGS
and since we actually do not need to use blkid there, introeduce
test variable HAVE_BLKID_SUBLKS_FSINFO and avoid trying to
use blkid.h in this place - this also fixes builing problem for
systems without blkid.h.

be124ae810 vgimportclone: fix non-duplicate PV with non-unique basevgname arg
Fix hang of vgimportclone command when:
the PV(s) being imported are not actually clones/duplicates, and
the -n vgname arg is the same as the current vgname.

(Not the intended use of the command, but it should still work.)

In this case, the old and new vgnames ended up being the same, when
the code expected they would be different.  A file lock on both the
old and new vgnames is used, so when both flocks are on the same
file, the second blocks indefinitely.

Fix the new vgname to be the old name plus a numeric suffix, which
is the expected result.

c9fdc828ff vgchange autoactivation: skip regex filter containing symlinks
"vgchange -aay --autoactivation event" is called by our udev rule.
When the udev rule runs, symlinks for devices may not all be created
yet.  If the regex filter contains symlinks, it won't work correctly.
This command uses devices that already passed through pvscan.  Since
pvscan applies the regex filter correctly, this command inherits the
filtering from pvscan and can skip the regex filter itself.

See the previous commit

17a3585cbb pvscan: use alternate device names from DEVLINKS to check filter
pvscan --cache <dev> is called by our udev rule at a time when all
the symlinks for <dev> may not be created yet (by other udev rules.)
The regex filter in lvm.conf may refer to <dev> using a symlink name
that hasn't yet been created, which would cause <dev> to not match
the filter regex.  The DEVLINKS env var, set by udev, contains all
the symlink names for <dev> that have been or will be created.
So, we add all these symlink names to dev->aliases, as if we had
found them in /dev.  This allows <dev> to be recognized by a regex
filter containing a symlink for <dev>.

908555459f toollib: do not process just created historical LV
When executing process_each_lv_in_vg, we process live LVs first and
after that, we process any historical LVs. In case we have just removed
an LV, which also means we have just made it "historical" and so it
appears as fresh item in vg->historical_lvs list, we have to skip it
when we get to processing historical LVs inside the same process_each_lv_in_vg
call.

The simplest approach here, without introducing another LV list, is to
simply mark such historical LVs as "fresh" directly in struct
historical_logical_volume when we have just removed the original LV
and created the historical LV for it. Then, we just need to check the
flag when processing historical LVs and skip it if it is "fresh".

When we read historical LVs out of metadata, they are marked as
"not fresh" and so they can be processed as usual.

This was mainly an issue in conjuction with -S|--select use:

	#  lvmconfig --type diff
	metadata {
		record_lvs_history=1
	}

(In this example, a thin pool with lvol1 thin LV and lvol2 and lvol3 snapshots.)

	#  lvs -H vg -o name,pool_lv,full_ancestors,full_descendants
	  LV    Pool FAncestors  FDescendants
	  lvol1 pool             lvol2,lvol3
	  lvol2 pool lvol1       lvol3
	  lvol3 pool lvol2,lvol1
	  pool

	#  lvremove -S 'name=lvol2'
	  Logical volume "lvol2" successfully removed.
	  Historical logical volume "lvol2" successfully removed.

...here, the historical LV lvol2 should not have been removed because
we have just removed its original non-historical lvol2 and the fresh
historical lvol2 must not be included in the same processing spree.

0887896847 vgremove: remove online files in run dir

that /run is tmpfs, and that remains the primary way

will limit the number of unused online files using space
in /run.

264827cb98 lvresize: add new options and defaults for fs handling
The new option "--fs String" for lvresize/lvreduce/lvextend
controls the handling of file systems before/after resizing
the LV.  --resizefs is the same as --fs resize.

The new option "--fsmode String" can be used to control
mounting and unmounting of the fs during resizing.

Possible --fs values:

checksize
  Only applies to reducing size; does nothing for extend.
  Check the fs size and reduce the LV if the fs is not using
  the affected space, i.e. the fs does not need to be shrunk.
  Fail the command without reducing the fs or LV if the fs is
  using the affected space.

resize
  Resize the fs using the fs-specific resize command.
  This may include mounting, unmounting, or running fsck.
  See --fsmode to control mounting behavior, and --nofsck to
  disable fsck.

resize_fsadm
  Use the old method of calling fsadm to handle the fs
  (deprecated.) Warning: this option does not prevent lvreduce
  from destroying file systems that are unmounted (or mounted
  if prompts are skipped.)

ignore
  Resize the LV without checking for or handling a file system.
  Warning: using ignore when reducing the LV size may destroy the
  file system.

Possible --fsmode values:

manage
  Mount or unmount the fs as needed to resize the fs,
  and attempt to restore the original mount state at the end.

nochange
  Do not mount or unmount the fs. If mounting or unmounting
  is required to resize the fs, then do not resize the fs or
  the LV and fail the command.

offline
  Unmount the fs if it is mounted, and resize the fs while it
  is unmounted. If mounting is required to resize the fs,
  then do not resize the fs or the LV and fail the command.

Notes on lvreduce:

When no --fs or --resizefs option is specified:
. lvextend default behavior is fs ignore.
. lvreduce default behavior is fs checksize
  (includes activating the LV.)

With the exception of --fs resize_fsadm|ignore, lvreduce requires
the recent libblkid fields FSLASTBLOCK and FSBLOCKSIZE.
FSLASTBLOCK*FSBLOCKSIZE is the last byte used by the fs on the LV,
which determines if reducing the fs is necessary.

3c49a2e43c vgimportdevices: change result when devices are not added
When using --all, if one VG is skipped, continue adding
other VGs, and do not return an error from the command
if some VGs are added. (A VG is skipped if it's missing PVs.)

If the command fails during devices file setup or device
scanning, then remove the devices file if it has been
newly created by the command, and exit with an error.

If devices from a named VG are not imported (e.g. the
VG is missing devices), then remove the devices file if
it has been newly created by the command, and exit with
an error.

If --all VGs are being imported, and no devices are found
to include in the devices file, then remove the devices
file if it has been newly created by the command, and
exit with an error.

b4cc28c2ef lvmconfig: add --valuesonly option
The new --valuesonly option causes the lvmconfig output to contain only
values without keys for each config node. This is practical mainly in
case where we use lvmconfig in scripts and we want to assign the value
to a different custom key or simply output the value itself without the
key.

For example:

  # lvmconfig --type full activation/raid_fault_policy
  raid_fault_policy="warn"

  # lvmconfig --type full activation/raid_fault_policy --valuesonly
  "warn"

  # my_var=$(lvmconfig --type full activation/raid_fault_policy --valuesonly)

  # echo $my_var

81839cc4eb report: report numeric values (not string synonyms) for NUM and BIN fields with json_std format
Internally, NUM and BIN fields are marked as DM_REPORT_FIELD_TYPE_NUM_NUMBER
through libdevmapper API. The new 'json_std' format mandates that the report
string representing such a value must be a number, not an arbitrary string.
This is because numeric values in 'json_std' format do not have double quotes
around them. This practically means, we can't use string synonyms
("named reserved values") for such values and the report string must always
represent a proper number.

With 'json' and 'basic' formats, this is not an issue because 'basic' format
doesn't have any structure or typing at all and 'json' format puts all values
in quotes, including numeric ones.
