core: add some interops This also changes Verify to VerifyTx and VerifyWitnesses, because there is a need to pass a block for some interop functions.

Interops are designed to run under VM's execute() panic protection, so it's OK
for them to do things like
smth := v.Estack().Pop().Bytes()
even though technically Pop() can return a nil pointer.
