Nyall Dawson cc5b9bfe17 More QgsDistanceArea API cleanups and simplification
- setEllipsoidalMode() was removed. Ellipsoidal calculations are
now enabled whenever a valid ellipsoid() has been set. Set the
ellipsoid to 'NONE' to disable ellipsoidal calculations.

- ellipsoidalEnabled() was removed. Ellipsoidal calculations
are now enabled whenever a valid ellipsoid() is set. Check
willUseEllipsoid() to determine whether ellipsoidal
calculations will be performed.

- sourceCrs() and setSourceCrs() now always take and return
QgsCoordinateReferenceSystem objects. All string/ID based CRS
methods were removed.

- geographic() was removed. This was only used internally
in one place, so was replaced with sourceCrs().isGeographic() instead.

- some largely overlapping measurement functions were consolidated
