struct dh contains several pointer members corresponding to DH parameters: ->key, ->p and ->g. A subsequent commit will make the struct dh deserialization function, crypto_dh_decode_key(), to set these to constant static storage arrays for some of the well-known safe-prime groups. Turn the struct dh pointer members' types into "pointer to const" in preparation for this.
