Subject: * ext/openssl/ossl_pkey.h, ossl_pkey_rsa.c, ossl_pkey_dsa.c:   an
 instance variable "private" is added to OpenSSL::PKey class.   this ivar is a
 flag that shows whether there is a private key   in the instance.

* ext/openssl/ossl_engine.c: (ossl_engine_load_privkey): set private
  key flag.
