hashserv: Add unihash-exists API
Adds API to check if the server is aware of the existence of a given
unihash. This can be used as an optimization for sstate where a client
can query the hash equivalence server to check if a unihash exists
before querying the sstate cache. If the hash server isn't aware of the
existence of a unihash, then there is very likely not a matching sstate
object, so this should be able to significantly cut down on the number
of negative hits on the sstate cache.
