manifest: add matches() method

Move the code in context._manifestmatches() into a new
manifest.matches(). It's a natural place for the code to live and it
allows other callers to easily use it. It should also make it easier
to optimize the new method in alternative implementations of the
manifest (same reasoning as with manifest.diff()).
