40ed782077 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.

Possible --fs values:

checksize
  Only used when reducing the size, does nothing when exending.
  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_remount | resize
  Resize the fs if needed. Mounts or unmounts the fs as
  required (avoids mounting/unmounting when possible.)
  Attempts to restore the original mount state when finished.

resize_keepmount
  Resize the fs if needed, only if it can be done without
  changing the current mount state. Fail the command without
  resizing the fs or LV if an fs resize requires mounting or
  unmounting.

resize_unmount
  Resize the fs if needed, only while unmounted. Unmount the
  fs if needed.  Fail the command without resizing the fs
  or LV if an fs resize is needed that requires the the fs
  to be mounted.

resize_fsadm
  Use the old method of calling fsadm to do handle the fs
  (deprecated).

ignore
  Resize the LV without checking for or handling a file system.

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.

db5277c971 pvdisplay: restore --reportformat option
Fixes commit b8f4ec846 "display: ignore --reportformat"
by restoring the --reportformat option to pvdisplay.
Adding -C to pvdisplay turns the command into a reporting
command (like pvs, vgs, lvs) in which --reportformat can
be useful.

3b0f9cec7e filter-mpath: get wwids from sysfs vpd_pg83
to compare with wwids in /etc/multipath/wwids when
excluding multipath components.  The wwid printed
from the sysfs wwid file may not be the wwid used
in multipath wwids.  Save the wwids found for each
device on dev->wwids to avoid repeating reading
and parsing the sysfs files.

2ecfd503ed tests: add lvm_vdo_wrapper
Introduce a replacement vdo manager wrapper for testing.
When using test suite on a system without vdo manager (which has got
deprecated) - we still need its functionality to prepare 'vdo volume'
for testing lvm_import_vdo.

Wrapper currently need 2 binaries from older 'vdo 6.2' package -
to be named:
oldvdoformat - format VDO metadata with older format
oldvdoprepareforlvm - shift vdo metadata by 1MiB

1b070f366b vdo: fix conversion of vdo_slab_size_mb
When converting VDO volume, the parameter vdo_slabSize was
incorrectly copied as vdo_blockMapCacheSize, however this parameter
is then no longer used for any table line creation so the wrong
value was only stored in metadata.

Also use just single get_kb_size_with_unit_ and remove it's duplicate
functionality with get_mb_size_with_unit_.

Use $VERB for vdo remove call.

7ec0726ce3 toollib: fix segfault when handling selection with historical LVs
When processing historical LVs inside process_each_lv_in_vg for
selection, we need to use dummy "_historical_lv" for select_match_lv.

This is because a historical LV is not an actual LV, but only a tiny
representation with subset of original properties that we recorded
(name, uuid...).

To use the same processing functions we use for full-fledged non-historical
LVs, we need to use the prefilled "_historical_lv" structure which has all
the other missing properties hard-coded.

or could lead to using the devname idtype when a better
idtype is available.

f840dbb320 pvscan: warn about /dev/sda excluded by devices file
In most installations, /dev/sda* or /dev/vda* should be included
in system.devices because the root, home, etc LVs are usually on

Add a special case warning when a pvscan autoactivation command

either not listed or having a different device id.

6e22be20c6 devices file: warn about missing multipath entry
Warn if a scsi device is listed in the devices file that
is used by a multipath device that is not listed.  This
will happen if a scsi device is listed in the devices
file and then an mpath device is set up to use it.

The way to correct this would be to remove the devices
file entry for the component device and add a new entry
for the multipath device.
