30526046e7 native: don't push void result in Call
This was done in https://github.com/neo-project/neo/pull/1693
for native calls. `OnPersist` script still uses `DROP` though
as value is pushed via `CheckReturn` logic for regular calls.

d4c3a17883 interop/native: always use proper ScriptHashGetter, fix #924
All scripts are run in VM, so it's there to tell us about script hashes
involved and it must be used instead of nep5ScriptHash kludge.

and executed at the start of every block persisting.

8231953842 core: fix Neo.Contract.GetStorageContext security check
This syscall should only work for contracts created by current transaction and
that is what is supposed to be checked here. Do so by looking at the
differences between ic.dao and original lower DAO.

30836ca69b core/native: untangle native contracts initialization
The notion of NativeContractState shouldn't ever existed, native contract is a
contract and its state is saved as regular contract state which is critical
because we'll have MPT calculations over this state soon.

Initial minting should be done in Neo.Native.Deploy because it generates
notification that should have proper transaction context.

RegisterNative() shouldn't exist as a public method, native contracts are only
registered at block 0 and they can do it internally, no outside user should be
able to mess with it.

Move some structures from `native` package to `interop` also to avoid circular
references as interop.Context has to have a list of native contracts (exposing
them via Blockchainer is again too dangerous, it's too powerful tool).

a92872931c interop/crypto: allow ECDsaVerify to verify ScriptContainer
When verifying transaction or block, verification script can be
a simple PUSHNULL + SYSCALL, which means that script-encontaining
