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.
