Simplifies a lot of code and removes some duplication. Unfortunately I had to move test_util random functions in same commit to avoid cycle dependencies. One of these random functions was also used in core/transaction testing, to simplify things I've just dropped it there and used a static string (which is nice to have for a test anyway). There is still sha256 left in wallet (but it needs to pass Hash structure into the signing function).
