b5864cd432 [FEATURE] Improve handling of defaults (inc provider default clauses, 
literal defaults, and qgis expression defaults) and automatically
handle unique value constraints on layers

Add a new method QgsVectorLayerUtils::createFeature which returns
a new feature which includes all relevant defaults. Any fields
with unique value constraints will be guaranteed to have a value
which is unique for the field.

Currently only in use by the split feature tool.

747097d43d New method QgsVectorLayerUtils::createUniqueValue 
Returns a new unique attribute value for a layer. For numeric
fields this is the max attribute value + 1, for strings we
attempt to create a unique value by append _1, _2, etc to either
a specified 'seed' value, or failing that to the end of the
value of that field from the first feature in the layer.

3242321aa9 [FEATURE] Add method to get list of unique strings matching 
a substring from a vector data provider

Base implementation iterates through all features, but
providers can override with optimised versions. Native
implementations for postgres, spatialite and OGR included.

5b4a88f8e0 [feature] Add layer scoped actions 
Within the attribute table, there is a new button to trigger actions
which are not based on individual features but instead on the whole layer.
Normally they will perform actions based on all features or the selection.

In addition to this, a lot of cleanup has been done.

d6f09c012e [FEATURE] Add method to calculate pole of inaccessibility for polygons 
Implements a method in QgsGeometry and a processing algorithm to
calculate the pole of inaccessibility for a surface, which is the
most distant internal point from the boundary of the surface. This function
uses the 'polylabel' algorithm (Vladimir Agafonkin, 2016), which is an iterative
approach guaranteed to find the true pole of inaccessibility within a specified
tolerance. More precise tolerances require more iterations and will take longer
to calculate.

and also makes it obvious to users that they can use a fixed
CRS parameter in their model (as opposed to one taken from
a layer or input)
