Roman Khimov ec7e17ffa6 pkg: make use of the new crypto/hash package
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).
