30c13eff37 thin: report external origin
Use the field 'origin' for reporting external origin lv name.

For thin volumes with external origin, report the size of
external origin size via:

  lvs -o+origin_size

9d445f371c report: leave empty report field for 0
Since we do not support LVs with 0 size, use this value
as 'error' value for devices without origin, and leave this
field blank as in other cases.

e191780947 RAID: Make RAID 4/5/6 display sync status under heading s/Copy%/Cpy%Sync
The heading 'Copy%' is specific to PVMOVE volumes, but can be generalized
to apply to LVM mirrors also.  It is a bit awkward to use 'Copy%' for
RAID 4/5/6, however - 'Sync%' would be more appropriate.  This is why
RAID 4/5/6 have not displayed their sync status by any means available to
'lvs' yet.

Example (old):
[root@hayes-02 lvm2]# lvs vg
  LV      VG   Attr      LSize  Pool Origin Data%  Move Log Cpy%Sy Convert
  lv    vg   -wi-a----  1.00g
  raid1 vg   rwi-a-r--  1.00g                             100.00
  raid4 vg   rwi-a-r--  1.01g
  raid5 vg   rwi-a-r--  1.01g
  raid6 vg   rwi-a-r--  1.01g

This patch changes the heading to 'Cpy%Sync' and allows RAID 4/5/6 to print
their sync percent in this field.

Example (new):
[root@hayes-02 lvm2]# lvs vg
  LV    VG   Attr      LSize Pool Origin Data%  Move Log Cpy%Sync Convert
  lv    vg   -wi-a---- 1.00g
  raid1 vg   rwi-a-r-- 1.00g                               100.00
  raid4 vg   rwi-a-r-- 1.01g                               100.00
  raid5 vg   rwi-a-r-- 1.01g                               100.00
  raid6 vg   rwi-a-r-- 1.01g                               100.00

e4fdfa9d31 report: provide discard field value in full
I think it's better not to abbreviate human-readable fields like
'discard' to a single character.  Users can truncate it to the
first character themselves if they wish.

It's confusing to use the variable name discard for different things in
different places - use discard_str when it's a string not the enum.

dbb48de507 Add a new 'thin_pool' output field to 'lvs.
A gentle reminder that anyone relying on the output of reporting commands
like lvs in scripts must use -o to guarantee they get the fields they expect.

The default sequence of fields can change from release to release.
Equally, the 'attr' fields can have new values introduced and/or characters
appended to them.

55f6627427 Fix reading of released memory
lvseg_segtype_dup used memory pool vg memory pool for strind duplication.
However this one gets released before reporting happens so the command like:

pvs -o segtype

prints data from already released memory pool. Thanks to the fact there
is not much allocation happing after the VG is released, the memory
stays unmodified and correct result is printed.

Fix adds support for mempool passed parameter (like other similar
query commands) and uses dm_report memory pool for string duplication.

aec2115410 Const fixing
Fixing some const warnings - with API change in:

int vg_extend(struct volume_group *vg, int pv_count, const char *const *pv_names,

Change is needed - as lvm2api expects const behaviour here.
So vg_extend() is doing local strdup for unescaping.

skip_dev_dir return const char* from const char* vg_name.

Rest of the patch is cleanup of related warnings.

Also using dm_report_filed_string() API change to simplify
casting in _string_disp and _lvname_disp.

60fc088d70 Rename fields in lvm_property_type.
Based on review comments, rename a few fields in lvm_property_type.
In particular, change 'is_writeable' to 'is_settable', which is
more intuitive to the intent of the bitfield (a 'set' function
exists for this field/property).  Also, remove the char array
for 'id' - unnecessary as we can just use the string passed in
to do the strcmp.  Finally rename the union members from n_val
to 'integer' and 's_val' to 'string'.
