REVISION SUMMARY
  ~85 tests don't like our non-revlog file store for various reasons.
  
  This commit introduces hghave functionality for declaring and querying
  repository features. By default, we assume repositories have
  revlog-based file storage. But if the HGREPOFEATURES environment
  variable is set, we can override the default set of repository
  features. If you run the test harness with our simplestorerepo
  extension and an environment variable set to the proper value, you
  can override the hghave defaults to agree with simplestorerepo's
  version of reality.
  
  Various tests have been modified so behavior dependent on revlog-based
  file storage is marked as such.
  
  This fixes a handful of test failures with our custom file storage
  extension. But dozens remain. The point of this commit is to demonstrate
  how tests will need to be modified to account for custom storage
  implementations.
  
  TBH, I'm not convinced hghave is the proper layer for repository
  feature detection. I /think/ we'll eventually want something in
  run-tests.py itself. But that would require inventing a new primitive
  in the test harness. This is all very alpha at the moment. So I think
  hghave is an acceptable place to hang this feature detection. I think
  the right time to be thinking about integrating this into run-tests.py
  is *after* we have a stable alternate storage implementation in core.
  For now, let's try to make progress towards the idea of an alternate
  storage backend.
