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.
