b1cadb1822 Use generic algorithm icon for qgis algorithms which do not 
have specific icons, instead of generic qgis icon

We consider these 'top level' algorithms, and using the
standard algorithm icon should help reflect this and
differentiate them from 3rd party algorithms.

99cfb8faf3 Fix processing algs crash when no source features exist 
Instead we output an empty layer - this may be critical for
multi-step models where there is validly no features present
in a source layer

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.

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)
