8c878438f5 metadata: move vg parsing to vg_write
Parsing vg structure during  supend/commit/resume may require a lot of
memory - so move this into vg_write.

FIXME: there are now multiple cache layers which our doing some thing
multiple times at different levels. Moreover there is now different
caching path with and without lvmetad - this should be unified
and both path should use same mechanism.

c5e6bc393e metadata: read VG/LV profile name from metadata if it exists and load it
This is per VG/LV profile loading on demand. The profile itself is saved
in struct volume_group/logical_volume as "profile" field so we can
reference it whenever needed.

5d5f2306bd Add and track an "ondisk" pointer to struct volume_group.
This allows us to get the current on-disk version of the metadata whenever we
have the current in-flight version, without a recourse to scanning or lvmcache.

52f2f3eae4 Add free_orphan_vg
Move commod code to destroy orphan VG into free_orphan_vg() function.
Use orphan vgmem for creation of PV lists.
Remove some free_pv_fid() calls (FIXME: check all of them)
FIXME: Check whether we could merge release_vg back again for all VGs.

53d7985fa1 Add support to keep info about creation time and host for each LV
Basic support to keep info when the LV was created.
Host and time is stored into LV mda section.

FIXME: Current version doesn't support configurable string via lvm.conf
and used fixed version strftime "%Y-%m-%d %T %z".

bb115a7a6c Cache and share generated VG structs
Extend vginfo cache with cached VG structure. So if the same metadata
are use, skip mda decoding in the case, the same data are in use.
This helps for operations like activation of all LVs in one VG,
where same data were decoded giving the same output result.

Patch adds 1-to-1 connection between volume_group and lvmcache_vginfo.

077a6755ff Replace free_vg with release_vg
Move the free_vg() to  vg.c  and replace free_vg  with release_vg
and make the _free_vg internal.

Patch is needed for sharing VG in vginfo cache so the release_vg function name
is a better fit here.

3019419e95 Refactor vg allocation code
Create new function alloc_vg() to allocate VG structure.

It takes pool_name (for easier debugging).
and also take vg_name to futher simplify code.

Move remainder of _build_vg_from_pds  to _pool_vg_read
and use vg memory pool for import functions.
(it's been using smem -> fid mempool -> cmd mempool)
(FIXME: remove mempool parameter for import functions and use vg).

Move remainder of the _build_vg to _format1_vg_read

9b30dfb967 Use const char * for name and old_name in vg
Switch to use const char pointers to avoid changes of these structure
members and having better control over, were these members could
be modified.
