bitbake: bitbake: hashserv: Add hash equivalence reference server

Implements a reference implementation of the hash equivalence server.
This server has minimal dependencies (and no dependencies outside of the
standard Python library), and implements the minimum required to be a
conforming hash equivalence server.
