(1/4) dm_report support in libdevmapper

Hi,

This patch makes LVM2 to use dm_report in libdevmapper
instead of its lib/report functions.

Tested following commands where LVs of linear, striped,
mirrored
and snapshot exist and confirmed the output is same with
the
original LVM2 2.02.17.

  lvs
  pvs
  vgs
  lvs -a
  pvs -a
  lvs -a -o +devices
  lvs -o name,name,lv_name,vg_name
  lvs -a -o name,name,lv_name,vg_name
  lvs -a -o name,lv_name,vg_name -O name
  lvs -a -o name,lv_name,vg_name -O -name
  lvs -a -o name,lv_name,vg_name -O size
  lvs -a -o name,lv_name,vg_name -O lv_size
  lvs -a -o name,lv_name,vg_name -O -size
  pvs -o +pe_alloc_count,used,dev_size
  pvs -a -o +pe_alloc_count,used,dev_size

Thanks,
