59d8429cb3 Introduce lv_set_visible & lv_set_invisible and use lv_is_visible always. 
The vg->lv_count parameter now includes always number of visible
logical volumes.

Note that virtual snapshot volume (snapshotX) is never visible,
but it is stored in metadata with visible flag.

0b706ac672 Introduce link_lv_to_vg and unlink_lv_from_vg functions. 
link_lv_to_vg and unlink_lv_from_vg are the only functions
for adding/removing logical volume from volume group.

Only these function should manipulate with vg->lvs list.

d60f341d96 Remove vg->lv_count and use counter function. 
This should not cause problems but simplifies code a lot.

(the volumes_count is merged and renamed with lvs_visible
function by following patch.)

8f3fd69ffa Move metadata backup call after vg_commit. 
The backup() call store metadata from memory.

But in cluster backup() call performs
remote nodes metadata backup and it reads data from disk.

For metadata backup consistency,
patch moves all backup() calls after vg_commit.

(Moreover, some tools already do that this way.)

e24f357c23 Fix memory pool leak. 
Call the alloc_destory call always after finishing operation
with handle otherwise it will leak a memory pool.

Also fix return code in lv_extend.

aa8111b3cd fix some issues when compiling with -D DEBUG_POOL 
- fix compilation issues
- fix wrong pool object maipulation (lvm dumpconfig triggers assert)
- second iteration in loop _log_parallel_areas operates on non-existing object

42dee539e2 Do not issue write behind lv size. 
pvcreate $DEV
vgcreate -s 1k vg_test $DEV
lvcreate -l 1 -n lv1 vg_test
..
/dev/vg_test/lv1: write failed after 1024 of 4096 at 0: No space left on device

Just check for maximum write size in set_lv.

6d1b3b5385 Calculate mirror log size instead of hardcoding 1 extent size. 
It fails for 1k PE now.

Patch adds log_region_size into allocation habdle struct
and use it in _alloc_parallel_area() for proper log size calculation
instead of hardcoded 1 extent - which can fail.

Reproducer for incorrect log size calculation:
        DEV=/dev/sd[bcd]

        pvcreate $DEV
        vgcreate -s 1k vg_test $DEV
        lvcreate -m1 -L 12M -n mirr vg_test

https://bugzilla.redhat.com/show_bug.cgi?id=477040

The log size calculation is mostly copied from kernel code.

b47952641a Added displayable_lvs_in_vg and lv_is_displayable functions to deal with 
the counts of visible LVs from user's perspective consistently throughout
the code.

5da4feac0e Use temp table to set device size when converting mirrors. 
(Avoids having same mirror table loaded twice concurrently by first
using a 'zero' table to set the size of the device so when mirror
table is preloaded it doesn't have to be activated immediately.)
