  Add higher level pathspec API Right now, setting up a pathspec to be parsed and processed requires several data structures and a couple of API calls. This adds a new high level data structure that contains all the items that you'll need and high-level APIs that do all of the setup and all of the teardown. This will make it easier to use pathspecs in various places with less repeated code.
