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.

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

80de208a68 transaction: unbind GroupInputsByPrevHash from Transaction 
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).

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.

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

bfa2d54e16 rpc: move validateAddress() function from wrappers into server 
It's a server implementation detail, it has nothing to do with the data format
