* ext/openssl/ossl_asn1.c (obj_to_asn1bool): fixed ASN1::Boolean encoding issue for OpenSSL 1.0.0 compatibility. ASN1::Boolean.new(false).to_der wrongly generated "\1\1\377" which means 'true'. ASN1_TYPE_set of OpenSSL <= 0.9.8 treats value 0x100 as 'false' but OpenSSL >= 1.0.0 treats it as 'true'. ruby-ossl was using 0x100 for 'false' for backward compatibility. Just use 0x0 for the case OpenSSL >= OpenSSL 0.9.7. * test/openssl/test_asn1.rb: test added.
