Steven Watanabe ee613a6a28 Implement feature relevance.
* 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.
