Nyall Dawson 85f37eebb3 Add method to QgsAbstractGeometryV2 for boundary
Returns the closure of the combinatorial boundary of the
geometry (ie the topological boundary of the geometry).
For instance, a polygon geometry will have a boundary
consisting of the linestrings for each ring in the polygon.

Follows OGC / SQL/MM specs for boundary calculation
