Main Clair logic is changed in worker, updater, notifier for better adapting ancestry schema. Extensions are updated with the new model and feature lister and namespace detector drivers are able to specify the specific listers and detectors used to process layer's content. InRange and GetFixedIn interfaces are added to Version format for adapting ranged affected features and next available fixed in in the future. Tests for worker, updater and extensions are fixed.
