report: add new 'none' lv_layout and 'history' lv_role and mark historical LVs that way

Browse Source 
Report proper values for historical LVs in lv_layout and lv_role fields.
Any historical LV doesn't have any layout anymore and the role is "history".

For example:

$ lvs -H -o name,lv_attr,lv_layout,lv_role vg/-lvol1
  LV     Attr       Layout     Role
  -lvol1 ----h----- none       public,history
