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 
We don't need a map here, use simpler structures.

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.

8da20055d6 rpc: drop duplicating structures used in tests 
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 
Adjust structures accordingly and throw away most of them, they're useless.

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 
These might be undefined for mempool transactions, thus they should be defined
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.

a903147b60 keys: rename Signature to GetScriptHash, make it return Uint160 
Signature itself wasn't used at all and its name is very misleading, Uint160
script hash is way more useful.

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.

22f5667530 mempool: return fee along with tx when requesting tx

nice to have it returned from TryGetValue() also sometimes.
