7e34beec8c New API for traversal of geometry's vertices using iterator pattern 
Introducing:
1. STL-style iterator: QgsAbstractGeometry::vertex_iterator
2. Java-style iterator: QgsVertexIterator (built on top of STL-style)

The iterators are modeled after Qt's STL-style and Java-style iterators,
the idea is to replace nextVertex() method and later introduce iterators
for other bits (e.g. part_iterator, ring_iterator).

Since they can't be inlined anyway

54c988f918 Make QgsAbstractGeometry::toCurveType pure virtual, and implement 
for all geometry types

Previously this method would return nullptrs for many geometry
types

Add qgsgeometry_cast 
Because it
- is faster than dynamic_cast
- doesn't rely on RTTI
- encapsulates type checking in one place

a9d7630a69 Rename QgsPointV2 to QgsPoint and QgsPoint to QgsPointXY 
Because 3D coordinates should be the default.

af0d68b882 Implement QgsGeometry::isEmpty() 
Faster than QgsGeometry::isGeosEmpty() because it avoids the
conversion to GEOS geometries and just uses the QgsAbstractGeometry
subclasses directly.

Also implements faster isEmpty() overrides for specific
QgsAbstractGeometry subclasses.

Also improves the API to export/import WKB as QByteArray

49432a8468 Optimise QgsAbstractGeometry 
Make nCoordinates virtual, and provide shortcuts for some
geometry types. The base method which calls coordinateSequence()
is quite slow in certain circumstances.

Speeds up rendering point layers by ~25%, also likely to
speed up lots of geometry heavy operations throughout QGIS
