* ext/openssl/ossl_pkey_rsa.c (rsa_generate): [SECURITY] Set RSA

exponent value correctly.  Awful bug.  This bug caused exponent of
  generated key to be always '1'.  By default, and regardless of e
  given as a parameter.
    
  !!! Keys generated by this code (trunk after 2011-09-01) must be 
  re-generated !!! (ruby_1_9_3 is safe)
        
* test/openssl/test_pkey_rsa.rb: Add tests for default exponent and
  specifying exponent by a parameter.
