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.

14663348d0 Add {pv|vg|lv}_attr_dup() functions and refactor 'disp' functions.
Move the creating of the 'attr' strings into a common function so
they can be called from the 'disp' functions as well as the new
'get' property functions.
Add "_dup" suffix to indicate memory is allocated.
Refactor pvstatus_disp to take pv argument and call pv_attr_dup().

7bdc15c8bb Remove explicit double quotes from columns.h 'id' entries.
The 'id' entries in columns.h are the report field names.  Since these are
unique, we'd like to use them in generation of 'get' / 'set' functions.
As a step towards using them for this purpose, remove the explicit double
quotes and use the macro '#' character to add the double quotes back when
placing them into the '_fields' array 'id' member.

to change the field's value.

cdbe475fe3 Define new functions and vgs/pvs fields related to mda ignore.
Define a new pvs field, pv_mda_used_count, and a new vgs field,
vg_mda_used_count to match the existing pv_mda_count and vg_mda_count.
These new fields count the number of mdas that have the 'ignored' bit
clear (they are in use on the PV / VG).  Also define various supporting
functions to implement the counting as well as setting the ignored
flag and determining if an mda is ignored.  These high level functions
call into the lower level location independent mda ignore functions
defined by earlier patches.

Note that counting ignored mdas in a vg requires traversing both lists
and checking for the ignored bit on the mda.  The count of 'ignored'
mdas then is defined by having the bit set, not by which list the mda
is on.  The list does determine whether LVM actually does read/write to
the mda, though we must count the bits in order to return accurate numbers
for the various counts.  Also, pv_mda_set_ignored must search both vg
lists for ignored mda.  If the state changes and needs to be committed
to disk, the ignored mda will be on the non-ignored list.

Note also in pv_mda_set_ignored(), we must properly manage the mda lists.
If we change the ignored state of an mda, we must change any mdas on
vg->fid->metadata_areas that correspond to this pv.  Also, we may
need to allocate a copy of the mda, as is done when fid->metadata_areas
is populated from _vg_read(), if we are un-ignoring an ignored mda.

ea0cdd28c1 Separate PV label attributes which do not need parse metadata when reporting.
When reporting explicitly label attributes (pv_uuid for example), we do not
need to read metadata.

This patch separate the label fileds and removes scan_vgs_for_pvs
in process_each_pv() if not needed.

(There should be no user visible change in output.)

e9f57f2beb Add pv_mda_size to 'pvs' and vg_mda_size to 'vgs'.
Reports the size of the smallest metadata area in a PV or a VG.
Useful to confirm pvcreate --metadatasize or pvmetadatasize setting in
/etc/lvm/lvm.conf file.

NOTE: Actual value in these fields will most always differ from that
given in pvcreate options due to rounding and alignment effects.
