b461a6ab63 compiler: do not short-circuit in complex conditions 
Current implementation of short-circuting is just plain wrong
as it uses `last` or `before-last` labels which meaning depend
on context. It doesn't even handle simple assignements like
`a := x == 1 && y == 2`.

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

Closes #699, #700.

e213e69a33 network: rework shutdown sequence of Server 
Close transport and disconnect peers right in the Shutdown(), so that no new
connections would be accepted and so that all the peers would be disconnected
correctly (avoiding the same deadlock as in e2116e4c3f).

624a14f730 rpc: rename (*Client).SendToAddress to TransferAsset 
SendToAddress name is similar to the `sendtoaddress` RPC call,
this can cause confusion.

Closes #686.

3e2b490025 mempool: rework inputs verification, check Claim txes 
Use more efficient check for Input and also check Claims to avoid double
claiming.

00d199ed85 core: fix NetworkFee calculation 
Add doesn't change the variable state. Thanks to GolangCI for catching this.

29586f2aa7 core: add duplicate Claim verification check 
Refactor HaveInputsDuplicate() out of the core and Blockchain, it doesn't
depend on the Blockchain state. Make it more efficient.

9b1ad40273 core: drop GetScriptHashesForVerifyingClaim, fix Claim's ScriptHash getter 
Claim transactions should _add_ claims scripthashes to the standard list, not
replace them. And this code is actually very reusable.

9f7018503a core/transaction: use new transaction.InOut for References

Which allows to use it for ClaimTX. Make it also a bit more efficient as maps
are expensive.

c258adb532 core: move spent coin management out of the inner storeBlock loop 
prevHash == input.PrevHash, so make less DB accesses and more real work. Fix
some bugs along the way:
 * spentCoins structure may already be present in the DB when persisting TX,
   there is nothing wrong with that and we shouldn't overwrite it
 * it's only used for NEO and only to check for claim validity. Thus, when
   processing claim tx the corresponding spentCoins should always be present
   in the DB

36c6b6af14 core: put unspents get/put one loop above in storeBlock 
Everywhere in this code prevHash == input.PrevHash, thus we can easily move
some common code out of the loop saving on DB accesses and
serialization/deserialization.

5c9681508b transaction: strip off a layer of redirection from ClaimTX.Claims 
We don't need a pointer here and this change makes this field compatible with
Transaction.Inputs which is useful in many scenarios.

b49808b766 core: reschedule the next persist in a second from previous one 
It makes little sense queueing up several persistence goroutines (or actually
even running them concurrently).

e2116e4c3f network: don't deadlock on connection overflow 
(*Peer).Disconnect send an unregister signal to this goroutine, so invoking it
from here is not a good idea, run it asynchronously.

We have proper results now, so use those. The only left is Invoke, but that
depends on another issue at the moment.

3fa9de764b rpc/client: only return the Result from calls, handle Error internally

28a26d2cae rpc/client: look into data first, then HTTP error code 
In case of error our own server responds with an HTTP error and proper
JSON-RPC error in the body, so look there first as it has more specific data.

877b987ecf rpc: omitempty some fields in TransactionOutputRaw

as omitempty.

bba8ac15ff rpc: introduce proper type for sendrawtransaction, drop useless types 
sendrawtransaction just returns a bool, sendtoaddress returns a proper
transaction and that should be the same as the one we have in
TransactionOutputRaw.

f330f2f40b rpc: separate out request and response structures 
Mostly as is, no real effort done yet to optimize them, so there are still a
lot of duplicates there, but at least we sort them out into different smaller
packages.

bfa2d54e16 rpc: move validateAddress() function from wrappers into server 
It's a server implementation detail, it has nothing to do with the data format
itself. It also makes no sense exporing it.
