72ff89d279 Always use vg memory pool for allocated lv segment
Remove mem pool parameter from alloc_lv_segment()
Since we should always allocate LV segment from the vg mempool.

9ac61d2ba2 lvcreate parsing for thin provisioning.
The rest is incomplete so this isn't usable yet.

0adfbfd5ea Call add_pvl_to_vgs() and del_pvl_from_vgs() from more places.
Now that we have library functions to add/delete a pv from the vg->pvs
list, call them from everywhere.

a6a4941504 Move increment of vg->pv_count from import_pool_vg() to import_pool_pvs().
Move the increment of vg->pv_count next to the place where we add to
vg->pvs.  It looks safe to do this since the only caller of import_pool_vg()
calls import_pool_pvs() immediately afterward, and there is no way
import_pool_vg() can fail (always returns 1).  However, if there's a
memory allocation failure inside import_pool_pvs(), we will end up with
a different count in vg->pv_count that with the original code.  In any
case, vg->pv_count should be as close to dm_list_size(&vg->pvs) as
possible, as is the case everywhere else in the code.

f6644ff8fe Remove unnecessary parameter from import_pool_pvs().
The dm_list * parameter is unnecessary since we are passing in 'vg'
and the only caller of import_pool_pvs() passes '&vg->pvs' in the
dm_list * parameter.  Just use vg->pvs directly in the function.

aab7a3978b Fix pvmove allocation to take existing parallel stripes into account.
When moving parts of striped LVs, pvmove wouldn't care about leaving you with
two stripes on the same disk.  Now --alloc anywhere is needed for that.
(Tried and gave up on two alternative approaches before the one committed here.)

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.)
