Subject: [release/1.4.8] test, cmd/evm, core, core/vm: illegal code hash
 implementation

This implements a generic approach to enabling soft forks by allowing
anyone to put in hashes of contracts that should not be interacted from.
This will help "The DAO" in their endevour to stop any whithdrawals from
any DAO contract by convincing the mining community to accept their code
hash.

(cherry picked from commit 7a5b571c671e70e0e4807cf971c15e2d1e09d33d)
