Remove processing vector.uniqueValues/vector.getUniqueValues
and port usage to c++ method
Should be much faster than the python method, as the c++ method takes
advantage of handing off the unique values calculation to the
provider source whenever possible
- 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
Also
- simplify and add tests
- remove large memory leak (persistant store of all non-project layers)
- remove broken support for direct loading postgres/virtual layers
by string (Python version was very broken and would never match
a postgres/virtual layer)
- Add QgsGeometry method to densify by distance
- Fix bug in processing algorithm which resulted in duplicate
vertices and incorrectly spaced extra vertices

Because
- OTF reprojection is mature and stable
- Should be no cost when not required - transforms are shortcut
when not required
- Reduces code complexity
- Canvas OTF support was being incorrectly used as a flag for
whether measurements should be made in ellipsoidal mode. Instead
the project's ellipsoid setting should be checked for this.
- Should simplify behavior for new users
