D292: repair: move manifest strip to a separate function

REVISION SUMMARY
  This moves manifest stripping to a separate function so implementations of the
  manifest that don't support stripping can replace this function with a no-op.
  
  I considered adding a strip api to the manifestlog, so other implementations
  could make it a no-op there, but it seems like strip might be unique to the
  revlog implementation, and therefore shouldn't be present on the generic api.
