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.

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

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)

a0bd464232 Use formatted name for algorithm names
Avoids conversion of names later and gives clearer separation
between visible names and internal names
