display: use Virtual for virtual LV

Emphesize virtual extents for virtual LVs and for
those use  'Virtual extents' instead of 'Logical extents',
so it's immeditatelly visible, which extents do have
straighforward physical backend.

 Version 2.02.107 - 
 ==================================
+  Display virtual extents for virtual LVs in 'lvdisplay --maps'.
   Make vgsplit fail cleanly when not all PVs are specified for RAID 4/5/6.
   Make vgsplit work on mirrors with logs that share PVs with images.
   Use devices/ignore_suspended_devices=0 by default if not defined in lvm.conf.
