Start separating GOST 28147-89 from GOST R 34.11-94 



Hash function GOST R 34.11-94 (gosthash94) in its compression function
uses Russian block cipher (GOST 28147-89, Magma). Start separating block
cipher code from hash function code. For now there is no public
interface for this cipher, it will be added later.
