b75a174780 Rename QgsProcessingFeatureSinkDefinition to QgsProcessingOutputLayerDefinition 
Since it also applies to raster layer outputs, we need a more generic name

81da209bf5 Use a QgsProject pointer instead of bool loadIntoProject 
Allows potential future use case of loading results into
a different open project

72be86dc61 Only accept QgsPropertys in QgsProcessingFeatureSourceDefinition/ 
QgsProcessingFeatureSink, not all QVariant types

Only strings/QgsPropertys are valid anyway, so instead of strings
use static properties. This makes it clearer what possible
values are permitted for the underlying source/sink definition.

d7aa3f5f7c [processing] Change explicit encoding string parameters to more 
flexible QVariantMap creatOptions parameters which include an
optional fileEncoding value

More flexible, allows sinks to be created using any creation
option which is passed to the underlying provider

to control whether selected features only are to be used

to users when the selection will be respected

ed09a8a727 Create class for encapsulating settings relating to a feature source 
input to a processing algorithm.

This allows parameter inputs to encapsulate extra information
relating to a feature source input, such as whether only
selected features from the source layer should be used.

b6fb41d4ee [processing] Don't use vector layers directly as feature sources 
Instead, parameters evaluate to QgsFeatureSource, which are
used for retrieving features, feature count, crs, wkb type,
etc.

This abstracts away the actual feature source, so that
algorithms may potentially operate from non-layer
feature sources.

It also helps remove the need for specialised QgsProcessingUtils
methods like getFeatures, featureCount, and createSpatialIndex.
Instead the standard API methods using QgsFeatureSources can
be used instead.

005a08ead9 Create class for encapsulating settings relating to a feature sink 
input to a processing algorithm.

This allows parameter inputs to encapsulate extra information
relating to a feature sink input, such as destination file
encoding and whether the sink layer should be loaded into
the project on completion
