This patch adds the capability to split off a mirror legs.
It is pretty much the same as reducing the number of
mirror legs, but we just don't delete them afterwards.
The following command line interface is enforced:
prompt> lvconvert --splitmirror <n> -n <name> <VG>/<LV>
where 'n' is the number of images to split off, and
where 'name' is the name of the newly split off logical volume.
If more than one leg is split off, a new mirror will be the
result. The newly split off mirror will have a 'core' log.
Example:
[root@bp-01 LVM2]# !lvs
lvs -a -o name,copy_percent,devices
LV Copy% Devices
lv 100.00 lv_mimage_0(0),lv_mimage_1(0),lv_mimage_2(0),lv_mimage_3(0)
[lv_mimage_0] /dev/sdb1(0)
[lv_mimage_1] /dev/sdc1(0)
[lv_mimage_2] /dev/sdd1(0)
[lv_mimage_3] /dev/sde1(0)
[lv_mlog] /dev/sdi1(0)
[root@bp-01 LVM2]# lvconvert --splitmirrors 2 --name split vg/lv /dev/sd[ce]1
Logical volume lv converted.
[root@bp-01 LVM2]# !lvs
lvs -a -o name,copy_percent,devices
LV Copy% Devices
lv 100.00 lv_mimage_0(0),lv_mimage_2(0)
[lv_mimage_0] /dev/sdb1(0)
[lv_mimage_2] /dev/sdd1(0)
[lv_mlog] /dev/sdi1(0)
split 100.00 split_mimage_0(0),split_mimage_1(0)
[split_mimage_0] /dev/sde1(0)
[split_mimage_1] /dev/sdc1(0)
It can be seen that '--splitmirror <n>' is exactly the same
as '--mirrors -<n>' (note the minus sign), except there is the
additional notion to keep the image being detached from the
mirror instead of just throwing it away.

config: add silent mode
Accept -q as the short form of --quiet.
Suppress non-essential standard output if -q is given twice.
Treat log/silent in lvm.conf as equivalent to -qq.
Review all log_print messages and change some to
log_print_unless_silent.
When silent, the following commands still produce output:
dumpconfig, lvdisplay, lvmdiskscan, lvs, pvck, pvdisplay,
pvs, version, vgcfgrestore -l, vgdisplay, vgs.
[Needs checking.]
Non-essential messages are shifted from log level 4 to log level 5
for syslog and lvm2_log_fn purposes.
