#3292: Query on spatially overlapped features in one vector map

-------------------------+-------------------------
 Currently, v.what and the GUI query tool (based on v.what) can only find
 one feature that is the nearest from the user-specified location. Most of
 the time, this is OK, but when there are features overlapping each other,
 the user cannot query them all. It would be great to be able to find all
 features at a location, just like v.edit tool=select coor= using
 Vect_select_lines_by_polygon() instead of Vect_find_line().

 I attached a modified version of what.c for v.what and vector.py for GUI.
 These files query multiple overlapping line features in one vector map,
 but I wouldn't say that this is a good implementation because I'm not very
 familiar with the GUI code, which works together with v.what.
