Add a simple annotation layer that marks trailing whitespace in diffs (guarded by the `show_whitespace_errors` diff preference). The newly supported diff preference is added to both diff preference controls. The requirement that all annotation layers must implement `addListener` is relaxed as the trailing whitespace layer is the third layer that doesn't use it. Adds tests for the layer and the diff preference. Feature: Issue 4836 Change-Id: Ifba05216bf0bc3c0a8a094f5ef392b983091d59f
