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.

973d0bd5b7 report: fix lv_active column type from STR to BIN
Fix lv_active to be of BIN type instead of STR. This allows lv_active to
follow the report/binary_values_as_numeric setting as well as --binary
cmd line switch. Also, it makes it possible to use -S|--select with
either textual or numeric representation of the value, like 'lvs -S
active=active' but also 'lvs -S active=1'.

0eebd9d780 vgimportdevices: fix locking when creating devices file

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.

e6b6a09f90 args: add ARG_NONINTERACTIVE for cmds not supported in lvm shell
Certain args can't be used in lvm shell ("interactive mode") because
they are not supported there. Add ARG_NONINTERACTIVE flag to mark
such args and error out if we're in interactive mode and at the same
time we detect use of such argument.

Currently, this is the case for --reportformat arg - we don't support
changing the format per command in lvm shell. The whole shell is running
under a reportformat chosen at shell's start.

800436d2af libdm: report: fix escaping of JSON quote char in reported fields
Commit 73ec3c954b added a way to print
only a part of the report string (repstr) to support decoding individual
string list items out of repstr.

The repstr is normally printed through _safe_repstr_output so that any
JSON_QUOTE character ('"') found within the repstr is escaped to not
interfere with value quoting in JSON format.

However, the commit 73ec3c954b missed
checking the 'len' argument passed to _safe_repstr_output function when
adding the rest of the repstr after all previous JSON_QUOTE characters
were escaped (when calling the last dm_pool_grow_object). When 'len'
is 0, we need to calculate the 'len' ourselves in the function by
simply calling strlen. This is because 'len' is passed to the function
only if we're taking a part of repstr, not as a whole.

508782a913 shell: add pre-cmd log report object type and enable lastlog for it
If we failed or logged anything before we actually execute given command
in lvm shell, we couldn't report the log using lastlog command after.
This patch adds specific 'pre-cmd' log report object type to identify
such log messages and enables lastlog to report even this log.

e26c21cb8d vdo: extend volume and pool without flush
When the volume size is extended, there is no need to flush
IO operations (nothing can be targeting new space yet).
VDO target is supported as target that can safely work with
this condition.

Such support is also needed, when extending VDOPOOL size
while the pool is reaching its capacity - since this allows
to continue working without reaching 'out-of-space' condition
due to flushing of all in flight IO.

8a23683a59 config: remove unnecessary copy of config line's space prefix before printing
When we wanted to insert '#' before a config line (to comment it out),
we used dm_pool_strndup to temporarily copy the space prefix first so
we can assemble the final line with:

   "<space_prefix># <key>=<value>":

out of original:

  "<space_prefix><key>=<value>".

The space_prefix copy is not necessary, we can just use fprintf's
precision modifier "%.*s" to print the exact part if we alrady
know space_prefix length.

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
  "warn"

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.
