268f53ed0d lockd: fix error cases when built without lvmlockd
When lvm is built without lvmlockd support, vgcreate using a
shared lock type would succeed and create a local VG (the
--shared option was effectively ignored).  Make it fail.

Fix the same issue when using vgchange to change a VG to a
shared lock type.

Make the error messages consistent.

b93b85378d alloc: Fix lvextend failure when varying stripes.
A segfault was reported when extending an LV with a smaller number of
stripes than originally used.  Under unusual circumstances, the cling
detection code could successfully find a match against the excess
stripe positions and think it had finished prematurely leading to an
allocation being pursued with a length of zero.

Rename ix_offset to num_positional_areas and move it to struct
alloc_state so that _is_condition() can obtain access to it.

In _is_condition(), areas_size can no longer be assumed to match the
number of positional slots being filled so check this newly-exposed
num_positional_areas directly instead.  If the slot is outside the
range we are trying to fill, just ignore the match for now.

(Also note that the code still only performs cling detection against
the first segment of the LV.)

d947a815e8 config: make a difference between "not found" and "is empty" in log msg for devices/preferred_names
Replace misleading "not found" in the log message when
devices/preferred_names is set to empty array:

Really not found:
device/dev-cache.c:689   devices/preferred_names not found in config: using built-in preferences

Found, but empty:
config/config.c:1431   Setting devices/preferred_names to preferred_names = [ ]
device/dev-cache.c:689   devices/preferred_names is empty: using built-in preferences

d10fb73f63 config: also log the value used if defined in config, not just defaults
Commit 7e728fe1a1 added a log call
directly in find_config_tree_array when defaults are used.

This patch also adds the log for the value which is found in
existing configuration and for which defaults are not used.

For example:

Defaults used:
config/config.c:1428   devices/scan not found in config: defaulting to scan = [ "/dev" ]

Value defined in configuration used:
config/config.c:1431   Setting devices/scan to scan = [ "/dev", "/mydev", "/abc" ]

This makes the logging consistent with the other find_config_tree_* functions.

9ab6bdce01 vgchange: fix lock-start filtering and waiting
Both lock_start filters were being skipped when any lock-opt
values were used.  The "auto" lock-opt should cause the
auto_lock_start_list to be used.  The lock_start_list should
always be used.

The behavior of lock_start_list/auto_lock_start_list are tested
and verified to behave like volume_list/auto_activation_volume_list.

Since the default was changed to wait for lock-start to finish,
the "wait" and "autowait" lock-opt values are not needed, but a
new "autonowait" is added to the existing "nowait" avoid the
default waiting.

681f779a3c lockd: fix error message after a failing to get lock
There are two different failure conditions detected in

messages.  This adds another failure flag so the two
cases can be distinguished to avoid printing a misleading
error message.

ac3143c093 config: {thin,cache}_{check,repair}_options are never undefined
Require global/{thin,cache}_{check,repair}_options to be always defined.
If not defined directly by user in the configuration and if there's no
concrete default option to use, make "" (empty string) the default one -
it's then clearly visible in the "lvmconfig --type default" (and
generated lvm.conf) and also it makes its handling in the code more
straightforward so we don't need to handle undefined values.

This means, if there are no default values for these settings defined,
we end up with this generated now:
  {thin,cache}_{check,repair}_options = [ "" ]

So the value is never undefined and if it is, it's an error.

(The cache_repair_options is actually not used in the code at the moment,
but once the code using this setting is in, it will follow the same logic
as used for thin_repair_options.)

3da88b8917 lockd: allow vgexport and vgimport
The "exported" state of the VG can be useful with lockd VGs
because the exported state keeps a VG from being used in general.
It's a way to keep a VG protected and out of the way.

Also fix the command flags: ALL_VGS_IS_DEFAULT is not true for
vgimport/vgexport, since they both return errors immediately if
no VG args are specified.  LOCKD_VG_SH is not true for vgexport
beause it must use an ex lock to write the VG.

9cfa27f9c5 lockd: allow nolocking and readonly options
When --nolocking is used (by vgs, lvs, pvs):

. don't use lvmlockd at all (set use_lvmlockd to 0)
. allow lockd VGs to be read

When --readonly is used (by vgs, lvs, pvs, vgdisplay, lvdisplay,
pvdisplay, lvmdiskscan, lvscan, pvscan, vgcfgbackup):

. skip actual lvmlockd locking calls
. allow lockd VGs to be read
. check that only shared gl/vg locks are being requested
  (even though the actually locking is being skipped)
. check that no LV locks are requested, because no LVs
  should be activated or used in readonly mode
. disable using lvmetad so VGs are read from disk

It is important to note the limited commands that accept
the --nolocking and --readonly options, i.e. no commands
that change/write a VG or change/activate LVs accept these
options, only commands that read VGs.
