REVISION SUMMARY
  This refactors broken linkrev collection such that manifest collection is in a
  separate function. This allows extensions to replace the manifest collection
  with a non-revlog oriented version.
  
  I considered moving the collect changes function onto the manifestlog itself, so
  it would be behind the abstraction, but since the store we're building doesn't
  even have the concept of strip, embeding that concept in the manifestlog api
  seemed odd.
