e21015233b compiler: implement shadowing of global variables 
Before introducing slots it was hard to change global variables
preserving changes across multiple function calls.
This commit implements such possibility.
Closes #638.

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).

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

C# pushes value and key to the stack of non-serialized items, so key gets

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.

23464401bc core/state: merge spent and unspent coins state, use it to store more things 
This change reduces pressure on DB by doing the following things:
 * not storing additional KV pair for SpentCoin
 * storing Output right in the UnspentCoin, thus eliminating the need to get a
   full transaction from DB

At the same time it makes UnspentCoin more fat and hot, but it should probably
worth it.

Also drop `GetUnspentCoinStateOrNew` as it shouldn't ever existed, UTXOs
can't come out of nowhere.

1.5M block import time (VerifyBlocks disabled) on AMD Ryzen 5 1600/16GB/HDD,
before:
real    302m9.895s

3. (*DefaultDiscovery).RegisterBadAddr() tries to take mutex for write.

a9abd3d841 core: fix wrong endian used in interop functions 
C# uses ToArray() or UintXXX(bytes) here which interprets hashes as they
should be interpreted (BE, although they always convert to LE when converting
to String just for the fun of it). It leads to state difference for us at
block 2025204 where even though we have the same value for the key, the key
itself differs, ours:

dd2b538e2a0c1db1ae5061c15be14f916bd1e678e512ffcda6d9499d8e7fe97ee71fd6b8004583d9afe09cc4dadbd5deb63d01e061009b7cffdaa674beae0f930ebe6085af900093e5fe56b34a5c220ccdcf6efc336fc5000000000000000000000000000000000010

theirs:

dd2b538e2a0c1db1ae5061c15be14f916bd1e67861e0013db6ded5dbdac49ce0afd9834500b8d61fe77ee97f8e9d49d9a6cdff12e5009b7cffdaa674beae0f930ebe6085af900093e5fe56b34a5c220ccdcf6efc336fc5000000000000000000000000000000000010

In this key there is a tx hash encoded
(e512ffcda6d9499d8e7fe97ee71fd6b84583d9afe09cc4dadbd5deb63d01e061 in LE used
by all the tools like neoscan).

I love Neo.

Current implementation of short-circuting is just plain wrong
as it uses `last` or `before-last` labels which meaning depend

`a := x == 1 && y == 2`.

This commit makes all jumps in such conditions local
and adds tests.

eb11e5fb11 core: implement basic policying support, fix #370 
Implement mempool and consensus block creation policies, almost the same as
SimplePolicy plugin for C# node provides with two caveats:
 * HighPriorityTxType is not configured and hardcoded to ClaimType
 * BlockedAccounts are not supported

Other than that it allows us to run successfuly as testnet CN, previously our
proposals were rejected because we were proposing blocks with oversized
transactions (that are rejected by PoolTx() now).

Mainnet and testnet configuration files are updated accordingly, but privnet
is left as is with no limits.

Configuration is currently attached to the Blockchain and so is the code that
does policying, it may be moved somewhere in the future, but it works for
now.

The problem is that the select in putPacketIntoQueue() only works the way it
was intended to after the `close(p.done)`, but that happens only after
successful unregistration request send. Thus, do disconnects the other way
around, first unblock queueing and exit goroutines, then destroy the
connection (if it wasn't previously destroyed) and only after that signal to
the Server.

1133bbe584 mempool: remove unverified transactions pool 
Our mempool only contains valid verified transactions all the time, it never
has any unverified ones. Unverified pool made some sense for quick unverifying
after the new block acceptance (and gradual background reverification), but
reverification needs some non-trivial locking between blockchain and mempool
and internal mempool state locking (reverifying tx and moving it between
unverified and verified pools must be atomic). But our current reverification
is fast enough (and has all the appropriate locks), so bothering with
unverified pool makes little sense.

b675903f52 mempool/core: redesign mempool dances on block acceptance 
We not only need to remove transactions stored in the block, but also
invalidate some potential double spends caused by these transactions. Usually
new block contains a substantial number of transactions from the pool, so it's
easier to make one pass over it only keeping valid items rather than remove
them one by one and make an additional pass to recheck inputs/witnesses.

794027a90b mempool: use one slice for both priorities 
It doesn't harm as we have transactions naturally ordered by fee anyway and it

The chain may already be more current than our dBFT state (like when the node

e5d0125a3f network: do async broadcast when processing P2P TX 
It can lead to some goroutine explosion, but supposedly it's better than
stalling other processing and eventually all of these goroutines should finish
their sends. Note that this doesn't change the behavior for RPC-relayed
transactions that are still waiting for the broadcast to finish ensuring
proper transaction distribution before returning the result to the client.
