commit 23750f677ef61b6bea4e81f23f335ad08fc49b51

    TEST: Enable and fix test_bn2padded() in test/bntest.c
    
    This looks like old code, written when the padded variety of BN_bn2bin()
    was developped, and disabled by default...  and forgotten.
    
    A few simple changes to update it to the current API is all that was
    needed to enable it.
