aaa6205d5a toollib: improve ignore_vg case in _process_pvs_in_vgs
ignore_vg now returns 0 for the FAILED_CLUSTERED case,
so all the ignore_vg 1 cases will return vg's with an
empty vg->pvs, so we do not need to iterate through
vg->pvs to remove the entries from the devices list.

Clean up whitespace problems in that area from the
previous commit.

b622a7fe3f toollib: fixes and cleanup of recent changes
- Fix problems with recent changes related to skipping in:
  . _process_vgnameid_list
  . _process_pvs_in_vgs

- Undo unnecessary changes to the code structure and readability.

- Preserve valid but minor changes:
  . testing FAILED bit values in ignore_vg
  . using "skip" value from ignore_vg instead of "ret" value
  . applying the sigint check to the start of all loops
  . setting stack backtrace when ECMD_PROCESSED is not returned,
    i.e. apply the following pattern:

	ret = process_foo();
	if (ret != ECMD_PROCESSED)
		stack;
	if (ret > ret_max)
		ret_max = ret;

513105c6ac toollib: ignore_vg() with skip is not locked
Extend/fix d8923457b8 commit.

'skip'-ed VG is not holding any lock - so don't unlock such VG.

At the same time simplify the code around and relase VG at a single
place and unlock only not skiped and not ignored VGs.

d8923457b8 toolib: fix ignore_vg
Rework ignore_vg() API so it properly handles
multiple kind of vg_read_error() states.

Skip processing only otherwise valid VG.

Always return ECMD_FAILED when break is detected.

Check sigint_caught() in front of dm iterator loop.

Add stack for _process failing ret codes.

4de7699855 cleanup: unify LV info and LV segment status reporting in combination with LVS, SEGS and PVSEGS reporting
Move common code into shared internal fn so the logic for getting the
LV info as well LV segment status is not scattered around - call common
_do_info_and_status to gather required parts in reporting handlers.

83308fdff9 cleanup: cleanup internal interface to acquire segment status
- Add separate lv_status fn (if we're interested only in seg status,
   but not lv info at the same time as it is with existing
   lv_info_with_seg_status fn). So we 3 fns:

     - lv_info (existing one, runs only info ioctl, fills in struct lvinfo only)

     - lv_status (new one, runs status ioctl, fills in struct lv_seg_status only)

     - lv_info_with_seg_status (existing one, runs status ioctl, fills
       in struct lvinfo as well as lv_seg_status)

 - Add more comments in the code explaining the difference between lv_info,
   lv_status and lv_info_with_seg_status and their return values.

 - Move decision whether lv_info_with_seg_status needs to call only
   status ioctl (in case the segment for which we require status is from
   the LV for which we require info) or separate status and info ioctl
   (in case the segment for which we require status is from different
    LV that the one for which we require info) into
   lv_info_with_seg_status fn so caller doesn't need to bother about
   this at all.

 - Cleanup internal interface for this seg status so it's more readable.

7f90ad84c1 report: add new LVSSTATUS and SEGSSTATUS report type
Similar to LVSINFO type which gathers LV + its DM_DEVICE_INFO, the
new LVSSTATUS/SEGSSTATUS report type will gather LV/segment + its
DM_DEVICE_STATUS.

Since we can report status only for certain segment, in case
of LVSSTATUS we need to choose which segment related to the LV
should be processed that represents the "LV status". In case of
SEGSSTATUS type it's clear - the status is reported for the
segment just processed.

d7e5f03888 refactor: rename struct lv_with_info used in reporting code to lv_with_info_and_seg_status
The former struct lv_with_info is renamed to lv_with_info_and_seg_status as it can
hold more than just "info", there's lv's segment status now in addition:

	struct lv_with_info_and_seg_status {
		struct logical_volume *lv;
		struct lvinfo *info;
		struct lv_seg_status *seg_status;
	}

Where struct lv_seg_status is:

	struct lv_seg_status {
		struct dm_pool *mem;
		struct lv_segment lv_seg;
		lv_seg_status_type_t type;
		void *status; /* struct dm_status_* */
	}

Where lv_seg points to lv's segment that is being reported or
processed in general.

New struct lv_seg_status keeps the information about segment status -
the status retrieved via DM_DEVICE_STATUS ioctl. This information will
be used for reporting dm device target status for the LV segment
specified.

So this patch introduces third level of LV information that is
kept for reuse while reporting fields within one reporting line,
causing only one DM_DEVICE_STATUS ioctl call per LV segment line
reported (otherwise we'd need to call the DM_DEVICE_STATUS for each
segment status field in one LV segment/reporting line which is not
efficient).

This is following exactly the same principle as already introduced
by commit ecb2be5d16.

So currently we have three levels of information that can be used
to report an LV/LV segment:

    - LV metadata itself (struct logical_volume *lv)

    - LV's DM_DEVICE_INFO ioctl result (struct lvinfo *info)

    - LV's segment DM_DEVICE_STATUS ioctl result (this status must be
      bound to a segment, not the whole LV as the whole LV may be
      composed of several segments of course)
      (this is the new struct lv_seg_status *seg_status)

a3a2c792a8 lv: lv_active_change add needs_exclusive flag
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).

bf4681ba13 report: cleanup: simplify LVSINFO detection
LVSINFO is just a subtype of LVS report type with extra "info" ioctl
called for each LV reported (per output line) so include its processing
within "case LVS" switch, not as completely different kind of reporting
which may be misleading when reading the code.

There's already the "lv_info_needed" flag set in the _report fn, so
call the approriate reporting function based on this flag within the
"case LVS" switch line.

Actually the same is already done for LV is reported per segments
within the "case SEGS" switch line. So this patch makes the code more
consistent so it's processed the same way for all cases.

Also, this is a preparation for another and new subtype that will
be introduced later - the "LVSSTATUS" and "SEGSSTATUS" report type.

c9fbbf48ba cache: support more args
Unlike with thin-pool - with cache we support all args also
directly when create cache volume.

So the result of 'separate' cache-pool creation and setting its
options should give same result as specifying those args
during cache creation.

Cache-pool values are used as defaults if the params are
not specified with cache creation.

lvcreate without -Z or -W will fallback to warning if the device
cannot be zeroed, however if user requested them explicitely
it will give user error.
