- Moving Item_func_spatial_mbr_rel from Item_bool_func2 to Item_bool_func,

as Item_func_spatial_mbr_rel needs nothing from Item_bool_func2.
- Renaming Item_func_spacial_rel (the class that implements precise spacial
  relations) to Item_func_spatial_precise_rel
- Adding a new abstract class Item_func_spatial_rel as a common parent
  for Item_func_spatial_precise_rel and Item_func_spatial_mbr_rel.
