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

ede452be85 [processing] Port feedback object to c++ 
Algorithms are now passed a QgsProcessingFeedback object
instead of the loosely defined progress parameter.

bd7d913379 Refine QgsFeature geometry getters/setters 
All pointer based methods have been removed.

Now we have only:

  void setGeometry( const QgsGeometry& geom )

and

  QgsGeometry geometry() const

Benefits include avoiding a whole lot of tricky pointer lifetime
issues, potential memory leaks, and finally closing #777, which
has survived for over 9 years!...

Impacts on PyQGIS code:
- no more need for the messy
  g = QgsGeometry( feature.geometry() )
  workaround, just use g = feature.geometry() instead
- IMPORTANT: you can no longer test whether a feature has geometry
 using `if f.geometry():`, since QgsFeature::geometry() will
 *always* return an object. Instead, use
 `if not f.geometry().isEmpty():`, or preferably the new method
 `if not f.hasGeometry():`

Fix #777
