d50c6d4bf5 Add new --sysinit option for vgchange and lvchange.
A shortcut for --ignorelockingfailure, --ignoremonitoring, --poll n options
and LVM_SUPPRESS_LOCKING_FAILURE_MESSAGES environment variable used all at
once in initialisation scripts (e.g. rc.sysinit or initrd).

b73c18242e Do not allow {vg|lv}change --ignoremonitoring if on clustered VG.
clvmd does not propagate DMEVENTD_MONITOR_IGNORE.

Update get_activation_monitoring_mode() to check if the VG that the
LV is being activated in is clustered.  If so, skip it.

Any get_activation_monitoring_mode() error will cause the associated LV
(or VG) to be skipped during activation.  Both vgchange_single() and
lvchange_single(), which call get_activation_monitoring_mode(), are
called by their respective process_each_..() method.

a6bc975a24 Improve activation monitoring option processing
. Add "monitoring" option to "activation" section of lvm.conf
. Have clvmd consult the lvm.conf "activation/monitoring" too.
. Introduce toollib.c:get_activation_monitoring_mode().
. Error out when both --monitor and --ignoremonitoring are provided.
. Add --monitor and --ignoremonitoring support to lvcreate.  Update
  lvcreate man page accordingly.
. Clarify that '--monitor' controls the start and stop of monitoring in
  the {vg,lv}change man pages.

cd69ee7453 Refactor lvchange_tag() to call lv_change_tag() library function.
Similar refactoring to vgchange - pull out common parts and put into
library function for reuse.  Should be no functional change.

7a8fa6aaab Add a [--poll {y|n}] flag to vgchange and lvchange to control whether
the background polldaemon is allowed to start.  It can be used
standalone or in conjunction with --refresh or --available y.

Control over when the background polldaemon starts will be particularly
important for snapshot-merge of a root filesystem.

Dracut will be updated to activate all LVs with: --poll n

The lvm2-monitor initscript will start polling with: --poll y

NOTE: Because we currently have no way of knowing if a background
polldaemon is active for a given LV the following limitations exist and
have been deemed acceptable:
1) it is not possible to stop an active polldaemon; so the lvm2-monitor
   initscript doesn't stop running polldaemon(s)
2) redundant polldaemon instances will be started for all specified LVs
   if vgchange or lvchange are repeatedly used with '--poll y'

6ee7d2aa53 Remove lockingfailed().
We provide a lock type that behaves like no_locking, but is not
  clustered. Moreover, it also forbids any write locks. This magically (and
  consistently) prevents use of clustered VGs, or changing local VGs with
  --ignorelockingfailure. As a bonus, we can remove the special hacks in a few
  places. Of course, people looking for trouble can always set their locking_type
  to 0 to override.

31f55a07db Fix convert polling to ignore LV with different UUID.
When mirror convert polling is started (mainly as backgound process,
in lvchange -a y or in lvconvert itself) it tries to read VG
and LV identified by its name.

Unfortunatelly, the VG can have already different LV under the same name,
and various more or less funny things can happen (note that
_finish_lvconvert_mirror suspends the volume for example).

(the typical example is our testing script which continuously recreates
LVs under the same name in the same VG.)

This patch adds optional uuid parameter which helps to properly
select the monitoring object. For lvconvert polling it is set to LV UUID
and both _get_lvconvert_vg and _get_lvconvert_lv uses it to read proper VG/LV.

(In the pvmove case it is NULL, here we poll for physical volume name).

8f3fd69ffa Move metadata backup call after vg_commit.
The backup() call store metadata from memory.

But in cluster backup() call performs
remote nodes metadata backup and it reads data from disk.

For metadata backup consistency,
patch moves all backup() calls after vg_commit.

(Moreover, some tools already do that this way.)

0296197999 Create global is_static() to eliminate from the library init function.
Very simple / crude method of removing 'is_static' from initialization.
Why should we require an application tell us whether it is linked
statically or dynamically to libLVM?  If the application is linked
statically, but libraries exist and dlopen() calls succeed, why
do we care if it's statically linked?
