EVP_PKEY_free() is refcounted on OpenSSL, but NOT under RSA SSL-C.
  Eliminate a number of test failures by conditionally reverting rev 1.79
  pubkey handling in ssl_engine_kernel.c, except under OpenSSL.

  Also revert a rev 1.79 bogisity for all toolkits; it's entirely bogus
  to release a refcount after setting aside the results in a persistant
  structure, in this case sslconn->client_cert from SSL_get_peer_certificate()
  mustn't be freed while sslconn is still in play.  The proper patch (not
  written yet) is to invoke the X509_free(sslconn->client_cert) when we
  cleanup the sslconn structure.
