156a2eddc5 compiler: support using return in some branches
When `return` is used in one codepath, but not the other,
we do not clean altstack properly. This commit fixes it.

977c431bf1 vm: implement ASSERT/ABORT opcodes
Rename THROWIFNOT to ASSERT, add ABORT opcode.
ABORT cannot be caught, but the implementation should be postponed until
exception handling is implemented.

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).

3dbe549a61 smartcontract: store MapType Parameter as a slice of KV pairs
Fixes #809.

Basically, there are three alternative approaches to fixing it:
 * allowing both []byte and string for ByteArrayType value
   minimal invasion into existing code, but ugly as hell and will probably
   backfire at some point
 * storing string values in ByteArrayType
   incurs quite a number of type conversions (and associated data copying),
   though note that these values are not changed usually, so dynamic
   properties of []byte are almost irrelevant here
 * storing only []byte values in ByteArrayType
   makes it impossible to use them as map keys which can be solved in several
   ways:
   - via an interface (Marshalable)
     which is good, but makes testing and comparing values in general harder,
     because of keys mismatch
   - using serialized Parameter as a key (in a string)
     which will need some additional marshaling/unmarshaling
   - converting MapType from map to a slice of key-value pairs
     not a bad idea as we don't use this map as a map really, the type
     itself is all about input/output for real VM types and this approach is
     also a bit closer to JSON representation of the Map

665bf78d11 vm: make map serialization more compatible with C#
C# pushes value and key to the stack of non-serialized items, so key gets
serialized first followed by value. Fixes #806.

Notice though that neither IDictionary in C#, nor map in Go have elements
ordered, so we can easily get a difference in KV pairs order and it would be
impossible to fix.

4758de71ec storage: optimize (*MemCachedStore).Persist for memory-backed ps
Most of the time it's persisted into the MemoryStore or MemCachedStore, when
that's the case there is no real need to go through the Batch mechanism as it
incurs multiple copies of the data.

Importing 1.5M mainnet blocks with verification turned off, before:
real    12m39,484s
user    20m48,300s
sys     2m25,022s

After:
real    11m15,053s
user    18m2,755s
sys     2m4,162s

So it's around 10% improvement which looks good enough.
