0b26b46234 state: store NEF instead of script for contract
NEFs for native contracts are set statically, thus
field values are taken from the reference implementation.

d93aa745bb contract: avoid going to the DB for entry scripts
This optimizes out DB access for non-deployed contracts under the assumption
that deployed ones are always loaded via `LoadScriptWithHash` (and if they're
not --- it's a bug anyway with the new hashing model) which actually is a very
popular case (every entry script does that).

204d7f1c6a core: refactor runtime.CheckWitness interop

fe1f0a7245 core: introduce CheckReturnState constants
At the moment we should have 3 possible options to check return state
during vm context unloading:
	* no check
	* ensure the stack is empty
	* ensure the stack is not empty

It is necessary to distinguish them because new _deploy method shouldn't
left anything on stack. Example: if we use _deploy method before some
ordinary contract method which returns one value. Without these changes
the contract invocation will fail due to 2 elements on stack left after
invocation (the first `null` element is from _deploy, the second element
is return-value from the ordinary contract method).

Part of #1055.

Also removed unreachable code: we can't have such situation when
script container is not a transaction in the scope of `CheckWitness`
method because:
1. Blocks have their own implementation of CheckWitness for
internal usage (it's (bc *Blockchain) verifyHeaderWitnesses method).
2. For the outside calls of System.Runtime.CheckWitness interop (e.g.
calls from smart-contract) script container is always a transaction.

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).
