Dirty tracking for Mobility attributes. See class-specific implementations for
details.

@see Mobility::Plugins::ActiveModel::Dirty
@see Mobility::Plugins::ActiveRecord::Dirty
@see Mobility::Plugins::Sequel::Dirty

@note Dirty tracking can have unexpected results when combined with fallbacks.
  A change in the fallback locale value will not mark an attribute falling
  through to that locale as changed, even though it may look like it has
  changed. See the specs for details on expected behavior.
