_lv_mark_if_partial_collect cannot fail, however it's good to keep
checking here as we do in all other cases.

f380cd7d98 Use unsigned type for bitmask
Using report_type_t for bitmask is not correct, since we have not defined types
for all  bit combinations - so switching to unsigned type, since values of
report_type_t enum are unsigned.

d2a3352755 Just code move of hash initialization in front of function
Make sure both hash tables are initialized before _read_sections() call.
Presents no functional change (since PV scan phase was not adding LV hashes),
but makes the code easier to handle mem failing case, and static analyzer is
hapier as well.

b9141fcefa Add stack traces for lock_vol failures
Adding at least stack traces with some FIXMEs for cases,
where we might want to do something cleaver - maybe fail command
or give user hints something is not going well ?

For remote_backup is stack probably 'good' enough for now.

c5b8faf3b1 Explicitely ignore fail error on hash_insert
We cannot do anything better here anyway - we are already in logging function,
so just ignore this issue here - it will most likely stop application later.

9bdfb30720 Fix allocation code to allow replacement of single RAID 4/5/6 device.
The code fail to account for the case where we just need a single device
in a RAID 4/5/6 array.  There is no good way to tell the allocation functions
that we don't need parity devices when we are allocating just a single device.
So, I've used a bit of a hack.  If we are allocating an area_count that is <=
the parity count, then we can assume we are simply allocating a replacement
device (i.e. no need to include parity devices in the calculations).  This
should make sense in most cases.  If we need to allocate replacement devices
due to failure (or moving), we will never allocate more than the parity count;
or we would cause the array to become unusable.  If we are creating a new device,
we should always create more stripes than parity devices.

d81498a824 Initialize dmeventd monitoring for every command
Read lvm.conf setting for monitoring for each command. So we should not
activate monitoring if the default compilation is set to monitor during
lvconvert commnads.

Patch also removes check for  clustered VG and allows to disable monitoring
for clustered VG with the assumption, the problem with monitoring and dmeventd
flag passing for INGNORE is already fixed.

ad48a46fc9 Make conversion from a synced 'mirror' to 'raid1' not cause a full resync.
It was not possible to pass down the DM_[FORCE|NO]SYNC flags to
'dm_tree_node_add_raid_target'.  This meant that converting to 'raid1' from
'mirror' would cause a full resync.  (It also meant that '--nosync' was
ineffective when creating a 'raid1' LV.)

I've taken the 'reserved' parameter in 'dm_tree_node_add_raid_target' and
used it for the "flags" parameter.  Now it is possible to pass the sync
flags and any other flags that may come up.

a30832cedd Fix bug that caused RAID devices to be unable to activate if sub-LV was missing.
Commit 02f6f4902f introduced a bug that caused
RAID devices to fail to activate if the device for a single sub-LV failed.
The special case of LVM mirror was handled, but not LVM RAID.
EXAMPLE:
[root@bp-01 ~]# devices vg
  LV            Copy%  Devices
  lv            100.00 lv_rimage_0(0),lv_rimage_1(0)
  [lv_rimage_0]        /dev/sde1(1)
  [lv_rimage_1]        /dev/sdh1(1)
  [lv_rmeta_0]         /dev/sde1(0)
  [lv_rmeta_1]         /dev/sdh1(0)
[root@bp-01 ~]# vgchange -an vg
  0 logical volume(s) in volume group "vg" now active
[root@bp-01 ~]# off.sh sdh
Turning off sdh
[root@bp-01 ~]# vgchange -ay vg --partial
  Partial mode. Incomplete logical volumes will be processed.
  Couldn't find device with uuid fbI0YO-GX7x-firU-Vy5o-vzwx-vAKZ-feRxfF.
  Cannot activate vg/lv_rimage_1: all segments missing.
  0 logical volume(s) in volume group "vg" now active

AFTER this patch:
[root@bp-01 ~]# vgchange -ay vg --partial
  Partial mode. Incomplete logical volumes will be processed.
  Couldn't find device with uuid fbI0YO-GX7x-firU-Vy5o-vzwx-vAKZ-feRxfF.
  1 logical volume(s) in volume group "vg" now active
[root@bp-01 ~]# devices vg
  Couldn't find device with uuid fbI0YO-GX7x-firU-Vy5o-vzwx-vAKZ-feRxfF.
  LV            Copy%  Devices
  lv            100.00 lv_rimage_0(0),lv_rimage_1(0)
  [lv_rimage_0]        /dev/sde1(1)
  [lv_rimage_1]        unknown device(1)
  [lv_rmeta_0]         /dev/sde1(0)
  [lv_rmeta_1]         unknown device(0)
[root@bp-01 ~]# dmsetup table vg-lv; dmsetup status vg-lv

0 1024000 raid raid1 2 AD 1024000/1024000

No WHATSNEW update necessary because this is an intrarelease fix.
