f1fe7af014 lv: add common lv_pool_lv fn for use in report and dup, use brackets for invisible devices
The common lv_pool_lv fn avoids code duplication and also
the reporting part now uses _lvname_disp and _uuid_disp to display
name and uuid respectively, including brackets for the name if the
dev is invisible.

fb957ef322 raid: Add metadata dev information to reports.
Add metadata_devices and seg_metadata_le_ranges report fields.
Currently only defined for raid, but should probably be extended
to all other segment types that don't report all their device
usage in the 'devices' field.

125cd06698 conf: make time format configurable
Make it possible to define format for time that is displayed.
The way the format is defined is equal to the way that is used
for strftime function, although not all formatting options as
used in strftime are available for LVM2 - the set is restricted
(e.g. we do not allow newline to be printed). The lvm.conf
comments contain the whole list that LVM2 accepts for time format
together with brief description (copied from strftime man page).

For example:
(defaults used - the format is the same as used before this patch)
$ lvs -o+time vg/lvol0 vg/lvol1
  LV    VG   Attr       LSize Time
  lvol0 vg   -wi-a----- 4.00m 2015-06-25 16:18:34 +0200
  lvol1 vg   -wi-a----- 4.00m 2015-06-29 09:17:11 +0200

(using 'time_format = "@%s"' in lvm.conf - number of seconds
since the Epoch)
$ lvs -o+time vg/lvol0 vg/lvol1
  LV    VG   Attr       LSize Time
  lvol0 vg   -wi-a----- 4.00m @1435241914
  lvol1 vg   -wi-a----- 4.00m @1435562231

b3a348c03c report: use same info also for lv_attr
Recently the single 'status' code has been used for number of cache
features.

Extend the API a little bit to allow usage also for lv_attr_dup.

As the function itself is used in lvm2api - add a new function:
lv_attr_dup_with_info_and_seg_status() that is able to use
grabbed info & status information.

report_init() is now using directly passed lvdm struct pointer
which holds the infomation whether lv_info() was correctly obtained or
there was some error when trying to read it.

Move 'healt' attribute to status.
TODO convert raid function to use the already known status.

Let's use this function for more activations in the code.

'needs_exlusive' will enforce exlusive type for any given LV.

We may want to activate LV in exlusive mode, even when we know
the LV (as is) supports non-exlusive activation as well.

lvcreate -ay   -> exclusive & local
lvcreate -aay  -> exclusive & local
lvcreate -aly  -> exclusive & local
lvcreate -aey  -> exclusive  (might be on any node).

17ab39f743 cache: include cache mode in vg metadata and display
The cache mode of a new cache pool is always explicitly
included in the vg metadata.  If a cache mode is not
specified on the command line, the cache mode is taken
from lvm.conf allocation/cache_pool_cachemode, which
defaults to "writethrough".

The cache mode can be displayed with lvs -o+cachemode.

ac60c876c4 vgsplit: Improve message when LV still active.
Mention parent LV as well as the LV triggering the warning.

Still leaves some confusing cases but its not worth fixing them
at the moment.
(Thin pool inactive but a thin volume active => deactivate thin vol.
Inactive mirror/raid with pvmove in progress => complete pvmove and
active&deactivate mirror/raid.
If new VG already exists it requires some LVs to be inactive
unnecessarily.)

2d3700ba42 report: improve reporting of active state
For reporting stacked or joined devices properly in cluster,
we need to report their activation state according the lock,
which activated this device tree.

This is getting a bit complex - current code tries simple approach -

For snapshot - return status for origin.
For thin pool - return status of the first known active thin volume.
For the rest of them - try to use dependency list of LVs and skip
known execptions.  This should be able to recursively deduce top level
device for given LV.

(in release fix)

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.
