c767ac2973 core: fix NEO native contract id 
It should be set to -1 as in c# implementation.

05dad10e82 native: fix native contract onPersist script 
C# implementation uses NEWARRAY for creating arguments.
Don't change our implementation in `emit`, because PACK is cheaper and
this script must not depend on the internal details of `emit` package anyway.

dd6895b103 native: optimize GAS onPersist for empty blocks 
There is no need to get a list of validators when there are no transactions in
the block.

3d18f09def core: fix CalculateClaimable for NEP5 NEO 
It's not stored as Fixed8, so calculations need to be adjusted for that.

39dfebccc4 core: no longer treat sysfee as claimable

being redistributed to CNs.

7e586cc6ab native: deduce transferred assets from sender on transfer 
When money is being sent usually they go away from someone's pocket, so that
there is a little less money left there. Not in our case as it turns out, we
actually were adding money both to sender and receiver which is nice, but a
bit different from usual economic's expectations.

c7a040ff81 core: fix bug with native contracts methods initialisation 
`NewNEO()` and `NewGAS()` methods are trying to initialise
both `onPersist` and `incBalance` methods of NEO and GAS AFTER
nep5TokenNative is set to the VALUE of created nep5 token.
In this situation an attemmpt to call the corresponding native contracts
methods (e.g. transfer native GAS) leads to contract invocation failure,
as far as `nep5TokenNative.incBalance` method is nil.

Fixed this by initializing both `onPersist` and `incBalance` methods
before getting the value of nep5 contract.

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).
