hashutil: new package for hashing-related features Right now this just tries to use our sha1dc and if it's missing (eg a --pure build) we fall back to hashlib. I imagine in the future we'll want some other things in here for detecting what hasher is in use as we transition off sha1. Differential Revision: https://phab.mercurial-scm.org/D7848
