Re: [RFC PATCH 2/8] hex-ll: split out functionality from hex

Separate out hex functionality that doesn't require a hash algo into
hex-ll.[ch]. Since the hash algo is currently a global that sits in
repository, this separation removes that dependency for files that only
need basic hex manipulation functions.
