Nyall Dawson bc98a326c0 [FEATURE] Add QgsVectorDataProvider::truncate for clearing layers
Adds a new method to QgsVectorDataProvider to truncate the layer.
The base implementation requires DeleteFeatures capability and
is not optimised. Providers can return the FastTruncate capability
and override the base implementation with a provider specific
optimised version. This is done in this commit for the Postgres
and Spatialite providers.
