[Pettycoin-dev] [raw_decode_base_n PATCH 3/3] Add a test for raw_decode_base_n with n=16

[Nelson Castillo]

This is the first time that we test raw_decode_base_* with a BIGNUM that
is allocated with BN_new. This function was leaking before and it doesn not
leak now that raw_decode_base_n does not call BN_init (Fixed in previous patch).

In other workds, this call sequence works well now:

  bn_priv = BN_new();
  assert(raw_decode_base_n(bn_priv, priv_b16, strlen(priv_b16), 16));
