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

4e18d54555 Tests and fixes for QgsPolygonV2
- Setting exterior ring will force all interior rings to match
dimensionality of exterior ring
- add equality operator
- use correct WKB types for rings when creating polygon from WKB
- segmentize curves when setting exterior ring with curved segments
- fix export to GML2/3 (should use LinearRing, not LineString as
ring element tag)

233f67b419 QgsPolygonV2 tests and fixes
- fixes for handling Polygon25D
- add QgsAbstractGeometryV2::convertTo( QgsWKBTypes::Type type ) for
easy conversion between geometry types
- fix crash when calculating perimeter with no exterior ring
- ensure that added rings respect dimensionality of polygon (avoids
issues such as polygons with z having a ring without z, or a
Polygon25D with LineStringZ rings)
- if a curved ring is added to a polygon then a segmentized version
of the ring is used (can't have a Polygon with a CircularString
ring)
- when calling setInteriorRings, make sure empty rings are skipped
and that all rings are converted to correct type for polygon
- don't crash when requesting or removing interior ring with
index < 0
