097ef2a731 core: copy storage item key in simple.GetStorageItems
Related to #1468, ported from #1475.

We should copy the key to avoid bytes substitution. Otherwise there's a
chance that at the end of dao.Store.Seek(...) execution some keys won't
be the same as the original keys found inside saveToMap function because
storage.Seek can guarantee that provided key and value are only valid
until the next `f` call.

a03af55732 core: provide monotonically increasing ID for contracts
ID is a contract identifier which doesn't change during migration.
It is also used as a part of storage context instead of contract hash.

a986e2a064 *: drop support for old on-chain assets
You no longer can transfer them, so creating/renewing/storing doesn't make
much sense.

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).
