f84d703234 Add method QgsProcessingUtils::mapLayerFromString 
Algorithms and other processing code should use this method
(instead of dataobjects.getLayerFromString) to
retrieve layers from a string, as it considers the processing
context and allows resolving strings to temporarily stored layers.

This permits processing models to function correctly when
intermediate results are stored as memory layers. Subsequent
model algorithms can then access these temporary layers as inputs.
All temporary layers will be removed when the context object
is destroyed after the model algorithm is run.

0b0ccc9e9d Rename QgsVectorLayer::selectedFeaturesIterator to getSelectedFeatures 
It's more in line with QgsVectorLayer::getFeatures, hence a more
discoverable API

fd2c18ee16 Refactor processing writer to use QgsFeatureSink, and to store 
temporary output layers in the provided processing context

Should fix loss of intermediate memory layers when running
a multi-step model

f247a7cda3 Add c++ optimised uniqueValues method which respects processing context 
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

ee777447a9 [processing] Remove special handling for invalid geometries 
Instead rely on QgsFeatureRequest method. There's a temporary
loss of the feedback on encountering an invalid geometry
when abort on invalid is set, but that will be resurrected
when all of vector.features is moved to c++

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

377b181c4e Port more processing dataobjects methods to c++ 
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)
