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.

96f82296ae Change confusing message that is printed when a RAID device fails. 
s/Issue/Use/, otherwise it is easy to misread "Issue" as "Issuing" - causing
the user confusion as to whether the action was performed automatically or
whether they need to issue the command.

1456c3b298 Fix possible NULL pointer dereferences when updating mirror log. 
'_lv_update_log_type' takes a lvconvert_params argument so that it can pass
down the user's preference of 'region_size' and allocation_policy.  When
'mirror_remove_missing' was introduced (commit ID
95986e42a1) it didn't make sense to pass down
user preferences - so NULL was given instead.  While it may never happen in
practice, static analysis reveals that this argument could be dereferenced.
So, if the user preferences were not passed in, glean the necessary fields
from what is already set in the LV.

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 3 0 region_size 1024 2 253:2 253:3 - -
0 1024000 raid raid1 2 AD 1024000/1024000

No WHATSNEW update necessary because this is an intrarelease fix.
