merge revision(s) 55047: [Backport #12441]

	* ext/openssl/ossl_bn.c (try_convert_to_bnptr): Extracted from
	  GetBNPtr(). This doesn't raise exception but returns NULL on error.
	  (GetBNPtr): Raise TypeError if conversion fails.
	  (ossl_bn_eq): Implement BN#==.
	  (ossl_bn_eql): #eql? should not raise TypeError even if the argument
	  is not compatible with BN.
	  (ossl_bn_hash): Implement BN#hash.

	* ext/openssl/ossl_bn.c (Init_ossl_bn): Define #== and #hash.

	* test/openssl/test_bn.rb: Test BN#eql?, #== and #hash
