97617cfc76 Fix incorrect memory pool deallocation while using vg_read for files.
We create a separate pool "lvm2 vg_read" for vg_read and we don't use
cmd->mem anymore.

360f97c31d Replicator: update activate code for vgchange
Activate only the first replicator-dev LV, that activates all other
related LVs from Replicator. In case of error during this activation,
it will not retry again for other heads (less confusing error log).

b68340f6d9 Fix scripts/relpath.awk to work with mawk
length(array) is specific to GNU awk and doesn't work in mawk.
Use a return value of "split" function to indicate array size, this is
supported in both gawk and mawk.

This patch fixes the following errors during "make install" when mawk is
installed as a default awk.

mawk: scripts/relpath.awk: line 25: illegal reference to array from
mawk: scripts/relpath.awk: line 25: illegal reference to array to

5257248ed9 Replicator: use cmd_vg for process_each_lv_in_vg()
As for _process_one_vg() we need similar retry loop for
process_each_lv_in_vg(). This patch retries to process
failed LVs with reopened VGs.

Patch does not add any extra repeated invocations if there is not
found any missing VG during LV processing.

780010a268 Replicator: use cmd_vg list for _process_one_vg()
Patch modifes behavior of _process_one_vg().

In the first pass vg_read() collectis for replicator sorted list of
additional VGs during lock_vol().
If any other VG is needed by the replicator and it is not yet opened
then next iteration loop is taken with all collected VGs.

Flag vg->cmd_missing_vgs detects missing VGs.

Introduce struct cmd_vg to store information about needed
volume group name, vgid, flags and the pointer to opened VG.

Keep VGs list in alphabetical order for locking order.

Introduce functions:
cmd_vg_add() add new cmd_vg entry.
cmd_vg_lookup() search cmd_vgs for vg_name.
cmd_vg_read() open VGs in cmd_vgs list.
cmd_vg_release() close VGs in reversed order.

451be927a8 Replicator: support deactivate of replicator-dev nodes
Introducing dm_tree_node_set_presuspend_node() for presuspending child
node (i.e. replicator control target) before deactivation of parent node
(i.e. replicator-dev target).

This patch presents no functional change to current dtree - only
replicator target currently sets presuspend node for dev nodes.

0d272a6964 Disallow toggling the cluster attribute of a volume group if there
are active mirrors or snapshots.

We don't have the mechanisms in place to change the device-mapper
tables for those targets that have behavioral differences between
cluster and single machine instances.  Allowing users to change
the attribute but not changing the target's behavior can lead to
data corruption.

The following bugs are fixed/avoided by this patch:
235123 - vgchange -c [ny] do not change target types when necessary
289331 - RFE: switching from cluster domain to local domain needs to deactivate volume somehow
289541 - when changing from local to cluster, volumes can not appear to be deactivated

2b129732b0 Skip also special lvm devices in scan (if ignore suspended is used).
This should avoid various races between dmeventd on multiple nodes
in cluster where one node already repairing device and another
run full scan and locks the device.

5ee39f1a1d Currently if clvmd is running and user issues vgscan,
the device cache file is dumped both in vgscan and clvmd process.

Unfortunately, clvmd calls lvmcache_label_scan,
it properly destroys persistent filter, but during
persistent_filter_dump it merges old cache content back!

This causes that change in filters is not properly propagated
into device cache after vgscan on cluster.
(Only new devices are added.)

ae11cc6731 Switch to use Requires.private for devmapper.pc and lvm2app.pc
Use Requires.private: instead of Libs.private:
Use UDEV_PC and SELINUX_PC for Require.private:

It looks like usage of Requires.private is prefered from Libs.private.
However pkg-config documentation is really poor here. But here is
short outcome:

There is a difference in Libs.private: and Requires.private: where
we specify libselinux instead of  -lselinux -lsepol.

We leave resolving of query like 'pkg-config --libs --static devmapper'
on taking proper selinux and udev libs to their .pc files instead of
hardcoding them into our .pc file which is might give incorrect answer.
- i.e. dependency of libselinux package might change and we may return
wrong list of linked libraries.
