Subject: * ext/openssl/ossl_pkey_rsa.c (ossl_rsa_public_encrypt,  
 ossl_rsa_public_decrypt, ossl_rsa_private_encrypt,  
 ossl_rsa_private_decrypt): should take an optional argument   to specify
 padding mode. [ruby-talk:122539]

* ext/openssl/ossl_pkey_rsa.c (Init_ossl_rsa): add new constants
  PKCS1_PADDING, SSLV23_PADDING, NO_PADDING and PKCS1_OAEP_PADDING
  under OpenSSL::PKey::RSA.

* test/openssl/test_pkey_rsa.rb: new file.
