0cb6dc47e4 vm: implement slot-related opcodes 
1. Slot is a new mechanism for storing variables during execution
which is more convenient than alt.stack. This commit implements
support for slot opcodes in both vm and compiler.
2. Remove old alt.stack opcodes.
3. Do not process globals at the start of every function, but instead
load them single time at main.

7287c01bd0 rpc/server: rework submitblock empty test 
The original intention here was to check for server reaction in presence of
validation errors (response.ErrValidationFailed) and it was very easy to make
validation fail for block without transactions in Neo 2. But in Neo 3
transactionless blocks are perfectly valid (see
29d321b5e1) which broke this test even though we
didn't see it until websocket addition (which required
8cec6694ae to make this test work initially).

So make a valid block and then spoil its verification script.

2ec1d76320 compiler: add ability to generate .abi.json file 
A part of integration with NEO Blockchain Toolkit (see #902). To be
able to deploy smart-contract compiled with neo-go compiler via NEO
Express, we have to generate additional .abi.json file. This file
contains the following information:
 - hash of the compiled contract
 - smart-contract metadata (title, description, version, author,
email, has-storage, has-dynamic-invoke, is-payable)
 - smart-contract entry point
 - functions
 - events

However, this .abi.json file is slightly different from the one,
described in manifest.go, so we have to add auxilaury stractures for
json marshalling. The .abi.json format used by NEO-Express is described
[here](https://github.com/neo-project/neo-devpack-dotnet/blob/master/src/Neo.Compiler.MSIL/FuncExport.cs#L66).

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).
