* New feature <relevant> which is automatically deduced in most cases. * Features which are not relevant do not affect target paths and do not prevent merging of virtual targets. * generators.jam: generator.run always returns usage-requirements to allow usage-requirements in non-top-level generators. This is necessary because we're using usage-requirements to track relevance from flags. * New rule toolset.uses-features to specify features that the rule checks manually, instead of using toolset.flags. In the future, we should consider restricting the properties actually passed, to detect errors. * Adjust tests to handle the new paths (verified by inspection). * Add temporary option --ignore-relevance to consider all features relevant to aid migration. * New rule property.evaluate-conditional-relevance which helps tracking relevance in <conditional>. * Widely scattered changes to use the new interfaces.
