ext/openssl: EVP_PKEY, DH, DSA, RSA, EC_KEY are made opaque

Use EVP_PKEY_get0_* instead of pkey->pkey.*
Use EVP_PKEY_base_id(pkey) instead of EVP_PKEY_type(pkey->type)

Because of this, we can no longer set the parameters/keys directly, and
the newly added functions as alternative require setting all relevant
values at the same time. So this patch contains incompatibility: the
following code no longer works (if using 1.1.0):

  dh = OpenSSL::PKey::DH.new(...)
  dh.priv_key = OpenSSL::BN.new(...)

...and we have to write like:

  dh = OpenSSL::PKey::DH.new(...)
  priv = OpenSSL::BN.new(...)
  pub = <calculate (dh.g ** priv) % dh.p>
  dh.set_key(pub, priv)
