138e125646 *: remove duplicate functions producing verification script
Drop wif.GetVerificationScript(), drop

directly to the PublicKey and use it everywhere.

8d4dd2d2e1 vm: move opcodes into their own package
This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.

And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.

The problem is that we're modifying `unsortedTxn` under a reader lock.

467c9c146d core: restore intermediate block-level store
Commit c80ee952a1 removed temporary store used
to contain changes of the block being processed. It's wrong in that the block
changes should be applied to the database in a single transaction so that
there wouldn't be any intermediate state observed from the outside (which is
possible now). Also, this made changes commiting persist them to the
underlying store effectively making our persist loop a no-op (and not
producing `persist completed` log lines that we love so much).

the `targetHash` itself which it should do in this particular case, otherwise
we end with no genesis block hash in the list.
