* Release GVL while OpenSSL's public key generation.

t = Thread.new { print "."; sleep 0.1 }
    key = OpenSSL::PKey::RSA.new(2048)
    #=> Thread t works in parallel with public key generation if
        OS/machine allows it.

  This works with OpenSSL >= 0.9.8. From this version, it has new 
  public key generation function which allows us to interrupt the
  execution while pkey generation iterations.

* ext/openssl/extconf.rb: Check existence of OpenSSL's new public key
  generation function. (DH_generate_parameters_ex,
  DSA_generate_parameters_ex and RSA_generate_key_ex.

* ext/openssl/ossl_pkey.{h,c} (ossl_generate_cb_2,
  ossl_generate_cb_stop): Added new callback function for OpenSSL pkey
  generation which handles Thread interruption by Ruby.
  ossl_generate_cb_stop is the unblock function(ubf) for Ruby which
  sets a stop flag. New pkey generation callback ossl_generate_cb_2
  checks the stop flag at each iterations of OpenSSL and interrupts
  pkey generation when the flag is set.

* ext/openssl/ossl_pkey_dsa.c (dsa_generate): Call
  rb_thread_blocking_region with the above unblock function to release
  GVL while pkey generation.

* ext/openssl/ossl_pkey_rsa.c (rsa_generate): ditto.

* ext/openssl/ossl_pkey_dh.c (dh_generate): ditto.

* test/openssl/test_pkey_{dh,dsa,rsa}.rb: Test it.
