f22c63ec77 Rely on upstream GEOS makevalid algorithm for GEOS 3.9+ 
No point having our own internal fork of this code now that it's
included (and more importantly, maintained) upstream!

1c11a91811 Add QgsGeometry::normalize() 
A port of the equivalent method from GEOS, but with added support
for curved geometries and M values

Reorganizes the geometry into a normalized form (or "canonical" form).

Polygon rings will be rearranged so that their starting vertex is
the lower left and ring orientation follows the right hand rule, collections
are ordered by geometry type, and other normalization techniques are applied.
The resultant geometry will be geometrically equivalent to the original geometry.

9c53fb8635 Add QgsAbstractGeometry::compareTo( QgsAbstractGeometry*) 
Allows for comparison of geometry objects, e.g. to allow for stable
sorting of them.

Ported from the GEOS equivalent method, but with addition of support
for M values and curved geometry types

d007901f14 Allow QgsRectangle constructors to bypass the automatic normalization 
step, when they know in advance they are already normalized

This step isn't free, and can add up when many rectangles are
constructed

6f4b32f658 Create class QgsAbstractGeometryTransformer, which can be used 
to transform the vertices of a QgsAbstractGeometry

E.g.

        class Transformer(QgsAbstractGeometryTransformer):

            def transformPoint(self, x, y, z, m):
                return True, x * 2, y + 1, z, m

        transformer = Transformer()
        g = QgsGeometry.fromWkt('LineString(3 0, 10 0, 10 10)')
        g.get().transform(transformer)
        print(g.asWkt()) # 'LineString (6 1, 20 1, 20 11)'
